Managing the Exploitation/Exploration Paradox: The Role of a
Learning Capability and Innovation Ambidexterity
Hsing-Er Lin, Edward F. McDonough III, Shu-Jou Lin, and Carol Yeh-Yun Lin
Some researchers have proposed that practices facilitating learning and knowledge transfer are particularly important
to innovation. Some of the practices that researchers have studied include how organizations collaborate with other
organizations, how organizations promote learning, and how an organization’s culture facilitates knowledge transfer
and learning. And while some have proposed the importance of combining practices, there has been a distinct lack of
empirical studies that have explored how these practices work together to facilitate learning and knowledge transfer
that leads to the simultaneous achievement of incremental and radical innovation, what we refer to as innovation
ambidexterity (IA). Yet, a firm’s ability to combine these practices into a learning capability is an important means of
enabling them to foster innovation ambidexterity.
In this study, learning capability is defined as the combination of practices that promote intraorganizational
learning among employees, partnerships with other organizations that enable the spread of learning, and an open
culture within the organization that promotes and maintains sharing of knowledge. This paper examines the impact
of this learning capability on innovation ambidexterity and innovation ambidexterity’s effect on business performance. The resource-based view (RBV) of the firm is used to develop a conceptual foundation for combining these
practices. This study empirically examines whether these practices constitute a learning capability by analyzing
primary data gathered from 214 Taiwanese owned strategic business unit (SBUs) drawn from several industries
where innovation is important.
The results of this study make four important contributions. First, they demonstrate that the combination of these
practices has a greater impact on innovation ambidexterity than any one practice individually or when only two
practices are combined. Second, the results demonstrate a relationship between innovation ambidexterity and business
performance in the form of revenues, profits, and productivity growth relative to competitors. Third, the results suggest
that innovation ambidexterity plays a mediating role between learning capability and business performance. That is,
learning capability has an indirect impact on business performance by facilitating innovation ambidexterity that in turn
fosters business performance. This study also contributes to our understanding of ambidexterity literature in a
non-Western context, i.e., Taiwan.

ust as juggling paradoxes is the test of a first-rate

of innovation at the same time. Too much focus on incremental product development and the firm runs the risk of

becoming obsolete. But too much focus on radical innovation runs the risk of bankrupting the company before it
has the chance to profit from its investment. For many
firms, perhaps most, succeeding in the long term means
finding the right way to undertake incremental and radical
innovation at the same time. But, identifying the “right”
way is not a simple task, and indeed, has consumed
researchers for quite some time. Researchers who have
focused on this task have been drawn to the notion of
ambidexterity to help resolve this paradox.
Ambidexterity has traditionally referred to the ability
to do two things at the same time (Gibson and Birkinshaw, 2004; He and Wong, 2004; Lubatkin, Simsek, Ling,
and Veiga, 2006; McDonough and Leifer, 1983; Simsek,
2009). But increasingly, researchers have used the notion
of ambidexterity to refer to a firm’s ability to engage in
exploratory activities leading to radical innovation on the
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
one hand and exploitative activities leading to incremental innovation on the other (Gibson and Birkinshaw,
2004; He and Wong, 2004; Lubatkin et al., 2006; Smith
and Tushman, 2005; Tushman and O’Reilly, 1996). The
importance of exploration and exploitation lies in their
potential for improving business performance and sustaining competitive advantage by enabling incremental
and radical innovation (cf. Gibson and Birkinshaw, 2004;
He and Wong, 2004).
March (1991) has noted however, that these two
activities compete for the same pool of scarce resources
which has often resulted in firms favoring one at the
expense of the other. Thus, the challenge facing firms and
researchers is to discover how to leverage a firm’s capabilities in ways that will enable it to successfully engage
in both types of activities simultaneously. Some researchers suggest that it is possible to balance the pursuit of
exploitation and exploration by creating a behavioral
context that is characterized by the interaction of stretch,
discipline, support, and trust (Gibson and Birkinshaw,

2004). Beyond the importance of fostering a behavioral
context (Gibson and Birkinshaw, 2004), however, there is
a marked lack of understanding the specific capabilities
that are required to simultaneously achieve radical and
incremental innovation (Adler, Goldoftas, and Levine,
1999; Simsek, Heavey, Veiga, and Souder, 2009).
Some researchers have proposed that practices facilitating learning and knowledge transfer are particularly
important to innovation (Kogut and Zander, 1992; Teece
and Pisano, 1994). Some of the practices that researchers
have studied include how organizations collaborate with
other organizations (Lichtenhaler, 2009; Mishra and
Shah, 2009), how organizations promote learning (Tsai,
2002), and how an organization’s culture facilitates
knowledge transfer and learning (Leonard-Barton, 1992).
And while some have proposed the importance of combining practices (Kogut and Zander, 1992; LeonardBarton, 1992), there have been few empirical studies that
have explored how these practices work together to facilitate learning and knowledge transfer that leads to the
simultaneous achievement of incremental and radical
innovation—what we refer to as innovation ambidexterity (IA). A firm’s ability to combine these practices into a
learning capability is important to enable them to foster
innovation ambidexterity.
In this study, learning capability is defined as the combination of practices that promote intraorganizational
learning among employees, partnerships with other organizations that enable the spread of learning, and an open
culture within the organization that promotes and maintains sharing of knowledge. Below, the resource-based
view (RBV) of the firm is used to develop a conceptual
foundation for combining these practices. Following this,
this study empirically examines whether these practices
constitute learning capability. The impact of this learning
capability on innovation ambidexterity is examined, as
well as innovation ambidexterity’s effect on business performance.
The results of this paper make four important contributions. First, they demonstrate that the combination of
these practices has a greater impact on innovation ambidexterity than any one practice individually or when only
two practices are combined. Second, these results demonstrate a relationship between innovation ambidexterity
and business performance in the form of revenues,
profits, and productivity growth relative to competitors
(Barney, 1991; Barney and White, 1998; Porter, 1991).
Third, these results suggest that innovation ambidexterity
plays a mediating role between learning capability and
business performance. That is, learning capability has an
indirect impact on business performance by facilitating
264

innovation ambidexterity that in turn fosters business
performance. This study also contributes to our understanding of the ambidexterity literature in Taiwan, a
non-Western context.
Taiwan presents an interesting context for this study
because of its innovation orientation including the development of high-technology products and creative design.1
Moreover, the latest Business Week ranking of the 50
most innovative companies in 2010 includes a number of
Taiwanese companies (e.g., HTC). Thus, it provides an
ideal context for a study that focuses on new product
innovation.
The rest of the paper is organized as follows. In the
next section, the theoretical basis for this study is developed, and definitions for key variables are provided. This
is followed by the literature review and hypothesis development. The section following this discusses the methodological approach. In the remaining sections, the
results and discussion are presented and followed by concluding remarks and suggestions for future research.
Theory and Definitions
Resource-based Theory of the Firm
and Capabilities
The resource-based view of the firm (RBV) views the
firm as a combination of resources and capabilities that
have the potential to provide the firm with a sustainable
competitive advantage (Amit and Schoemaker, 1993).
Resources, in this view, are defined as stocks of available
factors that are owned or controlled by the firm. These
resources are converted into final products or services by
using a wide range of other firm assets and bonding
mechanisms such as technology, management information systems, incentive systems, and trust between management and labor (Amit and Schoemaker, 1993; Barney,
1991). Capabilities are distinguished from resources.
They reflect a firm’s capacity to deploy resources. Thus,
in contrast to resources, capabilities are based on developing, carrying, and exchanging information. There is
general agreement among organizational capability
scholars that it is not the capabilities themselves, but
rather the application and use of these capabilities that
enable the firm to perform the activities they need to

perform, which provide advantage (Porter, 1991; Stalk,
Evans, and Shulman, 1992).
Knowledge is viewed as a resource that is core to an
organization’s ability to generate innovation and central
in the development of new products. Partnering with
other organizations, intraorganizational learning, and an
organization’s culture are practices that, when combined
together, form a capability that assists the organization to
integrate, reconfigure, gain, and utilize their knowledge
resource (Leonard-Barton, 1992). To foster innovation
ambidexterity, the combination of practices that are relied
upon need to enable the acquisition, dissemination, integration, and development of knowledge over time (Kogut
and Zander, 1992; Teece and Pisano, 1994). Interorganizational collaboration in the form of partnering with other
organizations and intraorganizational learning in the form
of idea exchange among the organization’s employees are
two practices that assist organizations in their search for
knowledge. A third practice is an organization’s culture,
which encompasses its values and norms of behavior.
Specifically, an open organization culture that emphasizes risk-taking, trust, respect for others, learning, and
searching for opportunities can provide the impetus for
employees to collaborate.
Ambidexterity, Exploitation, Exploration,
Innovation, and Business Performance
Research on ambidexterity has focused on various levels
of analysis including, a single business unit, diversified
organizations with several strategic business units
(SBUs), and the “realized view,” which focuses on either
SBUs or more diversified organizations (Simsek, 2009).
This study focuses on strategic business units to understand how they achieve innovation ambidexterity.
Research on ambidexterity has also interpreted ambidexterity as either simultaneously pursuing exploration
and exploitation (Beckman, 2006; Jansen, Van Den
Bosch, and Volberda, 2006; Lavie and Rosenkopf, 2006;
Lubatkin et al., 2006) or sequentially pursuing exploration and exploitation (Burgelman, 2002; Duncan, 1976).
Sequentially pursuing exploitation and exploration may
not entail ambidexterity in the sense of doing two things
equally well within the same time frame. Thus, the
research in this paper adopts what Simsek (2009) calls the
realized view of ambidexterity, where ambidexterity is
viewed as an organizational-level construct that is applicable to a single business unit whose goal is to achieve
high levels of both exploitation and exploration simultaneously (Simsek, 2009). In contrast, studies that adopt a
corporate level of analysis often view ambidexterity quite
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
differently. These studies consider firms to be ambidextrous when they have one organizational unit focused on
exploration leading to radical innovation and another
focused on exploitation leading to incremental innovation. Further, this study adopts the perspective on ambidexterity as an outcome resulting from the inputs of
capabilities at the organizational and interorganizational
levels. Thus, this study investigates the processes that
drive ambidextrous outcomes.
Simultaneously pursuing exploitation and exploration
within a single organizational unit is inherently challenging as a consequence of the competition for scarce
resources that often leads to conflicts, contradictions, and
inconsistencies (Simsek et al., 2009). In order to handle
these competing claims, organizations need to find the
right combination of different types of practices in order
that both incremental and radical innovations can be generated (Leonard-Barton, 1992). Interorganizational partnering and intraorganizational learning are two
behaviorally based practices that may help to generate a
variety of innovations.
However, motivating individuals to engage in these
behaviors requires using some type of social mechanism
(Lawson, Petersen, Cousins, and Handfield, 2009). One
such mechanism is an organization’s culture. Organization culture reflects the values of the organization. It is
these values that provide the impetus to engage in collaborative behaviors. Indeed, without norms and values
that foster collaborating internally and externally, collaboration, by itself, will have a limited effect on promoting the exchange of information and knowledge either
within or outside the organization. In this sense, these
practices need to work interdependently with each other
in order to become a capability that has the potential to
provide competitive advantage for the organization.
It is for this reason that this combination of practices is
critical to achieve innovation ambidexterity (LeonardBarton, 1992). While a particular practice may provide
some utility, it is when a set of practices are combined
together that they become an organizational capability
(Leonard-Barton, 1992). And it is this combinative effect
among these practices that enables the simultaneous
pursuit of explorative and exploitative activities that lead
to simultaneously generating multiple types of innovation
(Gupta, Smith, and Shalley, 2006).
This study further suggests that simultaneously attaining high levels of exploration and exploitation and the
accompanying high levels of incremental and radical
innovation is likely to lead to greater business performance in terms of revenues, profits, and productivity
growth relative to competitors (Barney, 1991; Barney and

elaborated.
Hypotheses
Innovation Ambidexterity and
Business Performance
Prior research suggests that firms capable of achieving
ambidexterity are likely to generate outcomes that are not
attainable if they emphasize one of these activities at the
expense of the other (Cao, Gedajlovic, and Zhang, 2009;
Gibson and Birkinshaw, 2004; He and Wong, 2004;
Tushman and O’Reilly, 1996). Indeed, as Colbert (2004)
points out, interactions, such as the interaction between
incremental and radical innovation, give “rise” to emergent properties that are irreducible because they exist
only in relationship.
Studies of the outcomes from achieving ambidexterity
have been quite varied. Atuahene-Gima (2005), e.g., suggests that the interaction of exploiting existing competencies and renewing and replacing them with new
competencies is positively related to radical innovation
performance. Prieto, Revilla, and Rodriguez (2007)
found that competence is positively related to new
product development performance in general. Simsek
et al. (2009) found that simultaneously combining exploitation and exploration within a single unit can improve
the satisfaction of stakeholders including customers and
upper-level managers. Concerning financial performance,
Han, Kim, and Kim (2001) suggest that a firm’s pursuit of
ambidexterity (versus pursuing incremental innovation
only) is positively associated with market share and
return on investment. He and Wong (2004) also found
that the ambidexterity achieved by the interaction of
exploitation and exploration learning is positively related
to self-reported compounded average rate of sales growth
over a 3-year period. Further, Schulze, Heinemann, and
Abedin (2008) suggest that ambidexterity has a positive
effect on subjective ratings of performance, measured as
a latent composite of operational and strategic planning.
These studies suggest that relationships exist between
exploitation, exploration, ambidexterity, and various sorts
of performance outcomes. Prior research, however, has
266
J PROD INNOV MANAG
2013;30(2):262–278
not investigated the attainment of innovation ambidexterity, on business outcomes. Yet, there are suggestions that
innovation ambidexterity (IA) may indeed lead to
enhanced business performance.
By engaging in both incremental and radical innovation, firms benefit by evading the disadvantages associated with becoming overly focused on one or the other
(cf., Han et al., 2001). However, pursuing radical innovation typically requires much more development time,
capital investment, risk taking, and failure tolerance than
incremental innovation (Amabile, 1997; Farson and
Keyes, 2002). Engaging in radical innovation also takes
more time as companies identify and search for sources
of useful knowledge within and outside the organization.
It is also relatively more difficult to estimate real-time
returns from radical innovation, although there is an
expectation that very large profits may result from the
commercialization of radical innovations (Levinthal and
March, 1993).
Incremental innovations, on the other hand, are built
on existing products and exploiting proximate knowledge, information, and feedback from customers, competitors, and markets (Tushman and O’Reilly, 1996). And
they are relatively effective in achieving predicted returns
in the short term (Raisch and Birkinshaw, 2008). While
incremental innovations are typically effective at
responding to the needs of customers and markets, they
are, at the same time, more easily imitated and substitutable. Thus, it has been argued that organizations that
engage solely in incremental innovation risk failing to
stay abreast of new knowledge (e.g., new technology and
materials) thus generating small returns. Researchers also
point out that a narrow knowledge search may lead to
highly limited specialized knowledge and know-how that
may eventually create rigidity in the organization
(Atuahene-Gima, 2005; Leonard-Barton, 1992), as well
as technological and knowledge obsolescence (Levinthal
and March, 1993).
In contrast, the combination of radical and incremental
innovation can provide significant advantage for the organization. On the one hand, radical innovation is more
likely to create new markets, generate greater market
share, and result in substantially higher returns for the firm
in the long term (Cao et al., 2009). On the other hand,
incremental innovation is more apt to improve and extend
the quality and added value of existing products that will
satisfy current customers’ needs (Cao et al., 2009).
This suggests that advantages can be gained from
undertaking both types of innovation and that the disadvantages associated with one type can be offset by the
other. Thus, when organizations engage in high levels of
H.-E. LIN ET AL.
both incremental and radical innovation, it is more likely
to result in greater overall business performance than if
only one form of innovation is undertaken.
Thus, it is proposed:
H1: A higher level of innovation ambidexterity will lead
to higher business performance in a business unit.
Learning Capability and Innovation Ambidexterity
Prior research has focused on investigating the effects of
separate practices on generating innovations (Lawson
et al., 2009). In order to generate IA, organizations need
to combine practices in ways that will generate high
levels of radical innovation and incremental innovation
simultaneously. Indeed, it has been argued that
sustainable competitive advantage relies on an organization’s ability to “reconfigure” its knowledge (Rosenkopf
and Nerkar, 2001). Kogut and Zander (1992) refer to this
as combinative capability, i.e., the ability “to synthesize
and apply current and acquired knowledge.”
The sources of the knowledge that is needed to generate innovation can be internal, i.e., inside the organization
from other individuals, units, departments, etc., or external, i.e., outside the organization, e.g., universities, other
companies, etc. (Helfat, 1994; Hull and Covin, 2010;
Jansen et al., 2006; March and Simon, 1958; Nelson and
Winter, 1982; Rosenkopf and Nerkar, 2001).
March and Simon (1958), Nelson and Winter (1982),
and Helfat (1994) have found that the innovation activity
of companies is closely related to their previous innovation activity, i.e., that it relies primarily on internal
sources. But innovative products emerge from variation
and from pursuing the untried instead of simply improving the existing ways of doing things (Sethi and Sethi,
2009). Thus, when learning and idea exchange occur only
among others in the organization, it may limit the potential for tapping into ideas that are foreign to the firm (cf.
Jansen et al., 2006). If individuals within an organization
hold the same basic experiences, values, and capabilities,
it makes it difficult to explore fundamentally different
knowledge bases and to create opportunities for acquiring
new knowledge and capabilities. And, since units operate
as part of a single firm, they are more likely to exchange
knowledge that is related to what they already know or
that is similar to their existing knowledge base. Thus,
they are more likely to pursue exploitative innovations
(cf. Jansen et al., 2006), and there is less likelihood that
radically new ideas will be generated when only intraorganizational learning is relied upon. It is also possible,
however, that such exploitative innovation can lead to
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
useful and important “next generation” products that can
add significantly to a company’s revenues stream (Benner
and Tushman, 2003).
On the other hand, other research suggests that external knowledge sourcing through interorganizational
partnering is an important source of learning that can
enhance a firm’s innovativeness (Allen and Cohen,
1969; Laursen and Salter, 2006; Lorenzoni and Lipparini, 1999; Shan and Song, 1997). Lorenzoni and Lipparini (1999), e.g., found that a firm’s ability to combine
its knowledge with knowledge from external sources
positively influenced its innovativeness. Rosenkopf and
Nerkar (2001) found that searching beyond organizational boundaries had more impact, as measured by
patent citations, than exploration within organizations.
Laursen and Salter (2006) also investigated the relationship between external search and innovation performance and found that focusing on a limited number of
organizations to search for new knowledge was associated with radical innovation.
The search process, whether it is externally or internally focused, involves acquiring knowledge and begins
as an individual activity (Kim, 1993). But the development of innovations usually requires teams of individuals
(Edmondson and Nembhard, 2009). Thus, organizations
need to find ways to combine practices in ways that will
facilitate the synthesis, exchange, and application of
acquired knowledge across individuals in the company
(Kogut and Zander, 1992; Teece and Pisano, 1994). One
avenue that is available to companies to accomplish this
is the use of social mechanisms such as the culture of the
organization (Lawson et al., 2009).
An organization’s culture (Schein, 1986) reflects the
personality of the organization that arises from the
assumptions, values, and norms that guide the behavior of
its members (Schein, 2004). In this sense, the culture of
the organization influences the way that people in the
organization accomplish their work, relate to one another,
and solve the problems that confront them on a daily
basis (Fayolle, Ulijn, and Degeorge, 2005). Because an
organization’s culture represents the values and norms of
behavior that are embraced by the members of the organization, it is likely to have a significant and enduring
impact on the behavior of people in the organization.
Thus, a culture that is competitive may cause individuals
to withhold knowledge from each other, whereas a
culture that promotes sharing and trust is likely to help
the distribution of knowledge and ideas (Hansen, Mors,
and Løvås, 2005; Lorenzoni and Lipparini, 1999).
Creating an open culture where individuals are willing
to take risks, trust and respect each other, learn, and
J PROD INNOV MANAG
2013;30(2):262–278
267
search for opportunities may be an effective means of
fostering the values, behaviors, and norms that will result
in the exchange, synthesis, and application of knowledge
(Hurley and Hult, 1998). Organizational culture in this
sense can be seen as a means of facilitating innovation.
Innovation requires flexibility, openness, collaboration,
and sharing. But these behaviors entail risk and indeed
demand that risks be taken. Sethi and Sethi (2009) found
that “teams that are strongly encouraged to take risk focus
more on exploration and are expected to question and
challenge the existing ways of doing things.” Also,
rewarding risk-taking behavior has been found to encourage people to look for new ideas, technologies, and
approaches that can result in more radical new products
(Amabile, 1988; Kanter, 1988; Mason and Mitroff, 1981;
Van de Ven, 1986).
But managing these risk-taking behaviors cannot be
accomplished through formal monitoring and control
(McDonough and Leifer, 1986). Instead, facilitating these
behaviors requires trust (Rousseau, Burt, and Camerer,
1998). A culture where individuals trust each other emboldens people to take risks in the form of exploring new
technologies, trying out new ideas, and sharing untested
ideas.
It would be incorrect to assume that individuals erect
artificial boundaries in their discussions with each other
by restricting their sharing to only exploitative or exploratory ideas. Practically speaking, it is difficult, if not
impossible, to know in advance the outcome of an idea or
if it will lead to a major breakthrough or a more modest
advance. Thus, this study suggests that it is the presence
of a culture of sharing that is important to fostering
exploitative and exploratory ideas that have the potential
to lead to incremental and radical innovations.
By creating an open organization culture, organizations can facilitate the synthesis, exchange, and application of knowledge that has been acquired from internal
and external sources. And it is this combination of practices that enables the organization to generate radical and
incremental innovations simultaneously (Lawson et al.,
2009). This combination of practices becomes a learning
capability that provides competitive advantage for the
organization by enabling it to engage in both exploitative
and explorative learning, thus leading to higher levels of
both incremental and radical innovation simultaneously
(Collis, 1994; Danneels, 2002; Gibson and Birkinshaw,
2004). Thus, it is proposed:
H2: When used in combination with each other, three
practices—intraorganizational learning, interorganizational partnering, and an open organization culture, i.e.,
268
J PROD INNOV MANAG
2013;30(2):262–278
a learning capability—will have a positive impact on
innovation ambidexterity.
The Mediating Effect of Innovation Ambidexterity
Finally, innovation ambidexterity may mediate the relationship between business performance and learning
capability. That is, the combination of intraorganizational
learning, interorganizational partnering, and an open
organization culture impact performance by achieving
innovation ambidexterity. A learning capability, by itself,
is likely to have limited influence on performance. In the
view of the RBV theory of the firm, it is the application
and use of a firm’s capabilities that enable the firm to
perform the activities it needs to perform that provide
advantage. Thus, the reason for hypothesizing a mediating effect is that it is the outcome of the application and
use of this learning capability that enables the firm to
perform the exploitative and exploratory activities that
are needed to produce both incremental and radical innovations, which, in turn, generate greater business performance (Porter, 1991; Ray, Barney, Waleed, and Muhanna,
2004; Stalk et al., 1992). Therefore, this study suggests
that unless these practices are combined together so as to
generate innovation ambidexterity, a learning capability,
in and of itself, will have a less positive impact on business performance than will the combined effects of a
learning capability and innovation ambidexterity.
Organizational capability theorists have indicated that
the importance of capabilities to organizations today is
much greater than it was before as a result of the relatively open and diverse sources of innovation now available to organizations (Teece, 2000). However, most
scholars also acknowledge that in order for a capability to
provide competitive advantage for a company, it must be
relatively scarce, difficult to imitate or duplicate through
other means, and contribute positively to performance
(Barney, 1991; Eisenhardt and Martin, 2000; Ray et al.,
2004).
This logic suggests that while every firm may possess
practices such as culture, intraorganizational learning,
and interorganizational partnering, not every firm can
effectively and efficiently combine them so as to create a
valuable and difficult to imitate learning capability
(Colbert, 2004). When the practices are effectively combined together, however, the combination creates properties that exist only as a consequence of the individual
practices being part of the whole. And these properties, in
turn, create an outcome, in the form of a capability that is
unavailable in their absence (Colbert, 2004). Based on the
above logic, it is proposed that the effect of a learning

capability will be felt through the process of innovation
ambidexterity that will subsequently generate greater
business performance (Porter, 1991; Ray et al., 2004;
Stalk et al., 1992). Thus, it is proposed:
H3: Innovation ambidexterity mediates the relationship
between a learning capability and business performance.
Methodology
Empirical Context
The empirical setting was the companies listed on the
General Chamber of Commerce of Taiwan and operating
in the chemicals, pharmaceuticals, financial management, mechanical engineering, and electronic engineering sectors. These sectors have been shown to be more
innovation oriented than others in the textiles, mining,
and steel industries in terms of the number of commercialized products and services. Additionally, Taiwan has
demonstrated an innovation orientation in many aspects,
e.g., Taiwan ranks number one in patents per million
people granted between January 1 and December 31,
2007, and Taiwanese companies rank number 16 in the
world in terms of R&D spending (see the World Economic Forum, Global Competitiveness Report 2008–
2009). Prior research has suggested that this context
could provide insights on innovation processes and their
effectiveness (cf. Elenkov, Judge, and Wright, 2005; Jibu
et al., 2007). The sampled companies had to meet two
criteria including (1) the importance of innovation to their
industry, and (2) the importance of innovation to the
company. Companies were contacted directly to ascertain
their interest in participating. Companies in these sectors
that fit the above criteria were invited to participate in the
survey within this sampling frame.
Following the suggestion of research on ambidexterity
that a business unit is a meaningful level at which to
examine organizational ambidexterity (Simsek, 2009),
this study was focused on the SBU level. An SBU is
defined as a profit center responsible for performance in
one or more markets with the authority to influence the
choice of the business’ competitive strategy in its target
markets. By focusing on the SBU, the likelihood that
each respondent is well acquainted with the strategies,
general processes, management, and performance of the
SBU is increased (Narver, Slater, and MacLachlan,
2004).
Data
To test the proposed hypotheses, primary data were
gathered from the sample. Following the suggestions of
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
Podsakoff, MacKenzie, Lee, and Podsakoff (2003), separate questionnaires were constructed to gather data for the
independent and dependent variables in order to avoid
self-report and self-evaluation that can result in common
method bias. To mitigate the potential problem of selfreport bias because the senior managers filled out the
questions about both business and innovation performance, a combination of prevention and detection
methods were used, as suggested by Podsakoff et al.
(2003). Prevention methods included collecting data at
two different points in time, approximately 1 year apart
(Jansen et al., 2006). Company contacts were also asked
to give the questionnaire in person to the best qualified
person to answer. The detection method consisted of conducting a validity check as described in the measurement
validation section. As Podsakoff et al. (2003) suggest,
using these methods minimizes self-report bias as a
concern in this study.
The set of survey questionnaires was distributed via
mail, fax, e-mail, or in person. Surveys were administered
to senior and middle level managers of 580 SBUs from 558
parent companies. One questionnaire was administered to
a senior level manager in each SBU who was asked about
the innovation and business performance of the SBU. A
different questionnaire was administered to middle-level
managers who were asked about organization culture,
intraorganizational learning, and interorganizational partnering. After the initial survey mailing, follow-ups were
conducted via reminder letters and telephone calls to the
company contacts. Two hundred fourteen sets of completed surveys were received from multiple informants
including 729 middle managers (1–12 respondents per
SBU) and 214 senior managers in 214 SBUs. Responses
were received from between 2 and 13 respondents per
SBU and 943 respondents from 214 SBUs. The response
rate for this study was 37% (214 SBUs completed out of
the 580 SBUs that were initially approached). Ten SBUs
were dropped from further analyses because of missing
data such as incomplete data on size, revenue, radical, or
incremental innovation performance.
Following Kanuk and Berenson (1975), potential nonresponse bias was further assessed by looking for differences between early and late respondents. The order of
responses to the survey was recorded and found to be
nonsignificantly correlated with SBU industry (r = .05,
p = .32) or SBU size (r = .01, p = .47). Performance differences on the early versus late-responding SBUs were
further compared and found to be nonsignificantly correlated with responding SBUs’ revenue (r = .02, p = .42),
suggesting that the concern regarding nonresponse bias is
minimal (Combs and Ketchen, 1999).

In this sample, the size of the SBUs in terms of the
number of employee ranged from 45 employees to over
3000. The mean size equaled 1037. Average age of the
SBUs in the sample was 17 years. One hundred and
ninety SBUs (89%) were privately owned. Twenty-eight
percent of the SBUs in the sample are in the business of
producing consumer products, 36% produce industrial
products, 22% produce consumer services, and 8%
produce industrial services. Thirty-five SBUs had revenues of $15–29 million, 66 had revenues of $30 million
to $1.5 billion, and 34 SBUs had revenues of $1.6–3
billion. Revenues were converted based on an exchange
rate of 1 US$ = 33 NTD.
Measures
The instruments were originally constructed in English
and were then translated into Chinese and back-translated
into English to ensure the accuracy of the meaning of the
questions. This study also used a mixture of positive and
negative questions in order to minimize response bias.
The questionnaires were then pretested using a sample of
managers in Taiwan. All constructs in this study were
measured on a 9-point Likert-type scale.
Dependent Variable
Business performance. Raisch and Birkinshaw
(2008) suggest that studies that use one-dimensional indicators of firm performance “run the risk of producing
biased estimations of organizational ambidexterity’s contributions to the firm’s overall success.” With this in
mind, a set of measures that provide a broader perspective
on firm performance were used. Specifically, the dependent variable was measured by using three items that
required senior management respondents to reflect on
performance relative to their competitors along three
dimensions: revenues, profits, and productivity growth
(Cao et al., 2009; He and Wong, 2004; Wakelin, 2001).
The Appendix contains these items. Respondents were
asked to indicate on a 7-point Likert scale where they felt
their SBU belonged on each of these dimensions.
Responses could range from much lower (= 1) to much
higher (= 7). Common factor analyses were conducted on
these items. Principal components extraction with an
Equamax rotation method (Eigenvalue > 1) resulted in
one factor. The Cronbach’s alpha was .82.
Mediating Variable and Independent Variables
Innovation ambidexterity. Innovation ambidexterity
is defined as attaining high levels of both incremental and
270
J PROD INNOV MANAG

radical innovation simultaneously. Because there was no
existing measure of ambidexterity exactly reflecting our
research purpose, a 6-item measure that reflected the
combination of incremental and radical product innovation performance was developed. The measures for each
type of innovation performance were adapted from the
work of Atuahene-Gima (2005) and Cooper and Kleinschmidt (2000). (The Appendix contains these items.)
Because senior managers are in the best position to
provide responses to our questions concerning innovation
performance, these managers were asked to look back
over the past 3 years and provide their perceptions of
innovation performance. It was felt to be important to use
a 3-year time period because of the lag effects that are
likely to exist between a firm’s innovativeness and its
actual impact on innovation performance.
In order to operationalize the combined concept of
innovation ambidexterity, the approach of He and Wong
(2004) and Cao et al. (2009) was followed to generate a
product term including incremental product and radical
product innovation. The reliability of the items used to
measure incremental product and radical product innovation was assessed. The Cronbach’s alpha for the items
measuring incremental product innovation was .78. These
items were combined into a single factor. The Cronbach’s
alpha for the items measuring radical product innovation
was .77. These items were combined into a single factor.
The overall Cronbach’s alpha for this factor was .82.
Traditionally, variables are centered before generating
product terms to avoid multicollinearity. Thus, the incremental product and radical product innovation scales
were mean-centered before obtaining their product to
mitigate the potential for multicollinearity (Cao et al.,
2009; He and Wong, 2004). These scores were then multiplied from these two factors for the overall measure of
innovation ambidexterity.
Learning capability. Middle managers were asked to
assess the practices of the firm. The measure of practices
was drawn from the work of O’Reilly, Chatman, and
Caldwell (1991), Tsai (2002), and Faems, Van Looy and
Debackere (2005) and consisted of 11 questions in total.
Because O’Reilly et al.’s (1991) measure of organization
culture was broader in scope than required for the purposes of this study, a subset of their items consisting of 5
items representing open organizational culture was used.
The measure of intraorganizational learning was derived
from work conducted in the area of knowledge sharing
and learning (cf. Tsai, 2002) and consisted of three questions. The measure of interorganizational partnering was
adapted from the work of Faems et al. (2005) and con-
H.-E. LIN ET AL.
sisted of three questions. All of the items comprising
learning capability are included in the Appendix.
To determine the number of items that contribute to
common variance actually needed to describe practices, a
common factor analyses was conducted on these items.
Principal components extraction with an Equamax rotation method (Eigenvalue > 1) resulted in three factors,
which paralleled the original three dimensions of practices. One factor consisted of 5 items representing open
organizational culture. Cronbach’s alpha was .91. One
factor consisted of three items representing intraorganizational learning. Cronbach’s alpha was .90. The other
factor consisted of 3 items representing interorganizational partnering. Cronbach’s alpha was .90. These items
were combined into a single factor (the overall Cronbach’s alpha was .92).
In order to operationalize the concept of learning
capability, He and Wong (2004) and Cao et al.’s. (2009)
approach was followed to generate a product term. In
order to avoid multicollinearity, the open organizational
culture, intraorganizational learning, and interorganizational partnering scores were mean-centered before
obtaining their product to mitigate the potential for multicollinearity (Cao et al., 2009; He and Wong, 2004).
Then, the scores from these three factors were multiplied
to derive our overall measure of learning capability.
Control Variables
Recognizing that innovation can be influenced by firm
and industry attributes, it is necessary to control for these
effects. Accordingly, two firm specific factors—SBU age
and size—as well as an industry-specific factor were
included as control variables, because prior studies have
documented their potential effects on organizational
innovation (cf. Elenkov et al., 2005; Jung, Wu, and Chow,
2008). The SBU size effects were controlled for by
including dummy variables. The sample was distributed
across four categories: 1 (50 employees and below), 2
(51–500 employees), 3 (501–1000 employees), and 4
(1001 and above). Therefore, three SBU size dummy
variables were constructed: 1 (50 employees and below),
2 (51–500 employees), and 3 (501–1000 employees).
Industries may differ in terms of technological orientations and innovation types, specifically, incremental
and radical innovation. The industry idiosyncratic effects
were controlled for by including dummy variables. The
sample was distributed across six sectors: (1) Chemicals,
(2) Pharmaceuticals, (3) Financial Management, (4)
Mechanical Engineering, (5) Electronic Engineering, and
(6) others. Thus, five industry dummy variables were
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
constructed: (1) Chemicals, (2) Pharmaceuticals, (3)
Financial Management, (4) Mechanical Engineering, and
(5) Electronic Engineering.
Aggregation
Because the theory and hypotheses of the study require an
SBU level of analysis, respondents’ individual scores on
each variable were aggregated, and the SBU mean
response was computed for each question (Keller, 1986).
After aggregation, the aggregation of SBU-level variables
was justified by calculating an interrater agreement score
for each variable (gwg), and then using intraclass correlation (ICC) to examine the degree of agreement among
respondents on each measure (cf. Goodman, Ravlin, and
Schminke, 1990; James, Demaree, and Wolf, 1984). The
average interrater agreement score (gwg) was .70 for open
organizational culture, .72 for intraorganizational learning, and .73 for interorganizational partnering. All were
above the cut-off value of .70. The ICC (1) and ICC (2)
values were .62 and .91 for open organizational culture,
.63 and .90 for intraorganizational learning, and .75 and
.90 for interorganizational partnering. All ICC values are
greater than or equal to .60 indicating acceptable reliability (Schneider, White, and Paul, 1998). Accordingly,
aggregation was justified for these variables and provided
substantial support for the scales.
Measurement Validation
Following Anderson and Gerbing’s (1988) suggestion, a
multistage process was performed to further assess convergent and discriminant validity of learning capability
and innovation ambidexterity through exploratory and
confirmatory factor analysis. Exploratory factor analysis
clearly replicated the five-factor model and did not reveal
any evidence of a single underlying construct. Next, a
confirmatory factor analysis was used on all items pertaining to learning capability and innovation ambidexterity. This analysis yielded a measurement model that fitted
the data adequately (c2 = 18.30, p < .05, c2/DF = 2.29,
CFI = .98, NFI = .96, RMSEA = .06). Item loadings were
as proposed (ⱖ.6) and significant (p < .01), providing
evidence for convergent and discriminant validity. As
noted in the measures subsection, Cronbach’s alphas for
all scales were greater than .70.
Analytical Procedures
Multiple regression analyses were performed to test the
hypotheses. Preacher and Hayes’s (2008) Macro syntax

was used to conduct the tests for Sobel and bootstrapping
directly within SPSS (SPSS, Chicago, IL, USA). The
approach combines the Sobel (1982) test and bootstrapping method to calculate standard errors and confidence
intervals. While using Baron and Kenny’s (1986) fourstep criteria informally judges whether or not mediation
is occurring, the Sobel test and bootstrapping methods
proposed by MacKinnon and Dwyer (1993) are a formal,
statistically based assessment for mediation. The Sobel
test was estimated with a normal distribution. Thus, it
needs to look at the standard error, standard score, and
confidence interval to indicate the reliability of an estimate. Bootstrapping is a resampling method that generates 95% bias-corrected and accelerated bootstrap
confidence intervals for the indirect effect using bootstrap
samples. The results of the Sobel and bootstrapping test
are reported to provide powerful estimation for the mediating effect.
First, the control variables (i.e., SBU industry dummy,
SBU age, and SBU size dummy) and innovation ambidexterity were included to examine the direct effect on
business performance. Second, the control variables and
learning capability were included to examine the direct
effect on innovation ambidexterity. Then, the mediating
effect of innovation ambidexterity on the relationship
between learning capability and business performance
was examined. In addition to testing the hypotheses, the
direct effects of individual practices, as well as the set of
two-way interactions of combinations of pairs of practices on business performance was also examined.
Results
The means, standard deviations, and pairwise correlations for the variables in this study are listed in Table 1.
Since significant correlations were found among a
number of the variables, potential multicollinearity using
variance inflation factors (VIFs) was further investigated.
The maximum VIF obtained in any of the models for
substantive variables was substantially below the rule-ofthumb cutoff of 2 for regression models (O’Brien, 2007).
Therefore, multicollinearity was not considered an
important issue for these results.
Table 2 summarizes the results for the direct effects of
innovation ambidexterity on business performance and
learning capability on innovation ambidexterity. Model 1
is the unconstrained controls-only model. The results
showed that only SBU age and the SBU industry dummy
2 (i.e., pharmaceuticals) were positively associated with
business performance. This finding is not surprising since
more established companies are more conducive to

higher business performance than less established ones
(Henderson and Clark, 1990), and companies in the pharmaceutical industry are relatively more highly innovative,
and higher innovativeness is typically associated with
greater business performance (Jibu et al., 2007).
Model 2 included the control variables and innovation
ambidexterity to test whether innovation ambidexterity is
positively related to business performance. The result
showed a positive association between innovation ambidexterity and business performance (b = .45, p < .05).
Thus, H1 was supported. To test H2, which predicted that
the interaction of learning capability is positively related
to innovation ambidexterity, Model 3, 4, and 5 were
tested proceeding in steps. Model 3 included the control
variables and the three practices: intraorganizational
learning, interorganizational partnering, and organization
culture. Model 4 included the control variables, the three
practices and three two-way interactions of pairs of practices and their product. Lastly, Model 5 included the
control variables, the three practices, and three two-way
interactions of pairs of practices and the three-way interaction term that is referred to as learning capability in this
study. The results showed that open organizational
culture was positively related to innovation ambidexterity
when there were no interaction terms included (b = .16,
p < .1; R2 = .17). When considering the three two-way
interactions, the cross-product term of intraorganizational
learning and interorganizational partnering was positively related to innovation ambidexterity (b = 1.25,
p < .1; R2 = .19). When the three-way interaction
term—learning capability—was included, only learning
capability had a positive relationship to innovation ambidexterity (b = .21, p < .1; R2 = .21). The results supported
H2 where it was argued that learning capability has a
stronger effect on innovation ambidexterity than any of
the individual practices or any pair of practices.
Model 6 and Model 7 were also tested to predict
whether the joint effect of learning capability and innovation ambidexterity has a stronger impact on business
performance than learning capability itself. The result
showed that learning capability itself has less impact on
business performance than the joint effect of learning
capability and innovation ambidexterity (R2 = .19 versus
.30, respectively).
The Sobel test and bootstrapping approach was used
to test the mediating effect of innovation ambidexterity
on the relationship between learning capability and business performance (H3). According to Sobel (1982), for

either partial or complete mediation to be established, the
reduction in variance explained by the independent variable must be significant. The results found a significant
reduction in variance (Z = 3.938, p < .05). Accordingly, it
can be concluded that innovation ambidexterity mediated
the relationship between learning capability and business
performance, providing support for H3 (Table 3). Table 3

Discussion and Conclusions
As Simsek and his colleagues (2009) have pointed out,
prior research has not provided answers to the question of
what organizations need to do in order to simultaneously
attain exploitation and exploration. Put differently,
researchers have not been able to suggest to managers the
specific levers they can pull to generate incremental and

radical innovation simultaneously. This study suggests
that one lever that may be important is a learning
capability.
Scholars have explicitly cited the need for additional
research that examines the combined effects of practices
for achieving incremental and radical innovation simultaneously (He and Wong, 2004). These researchers note
that doing so “may shed additional light on the subtle and
complex processes through which organizations achieve
and benefit from various combinations of exploration and
exploitation.” These results provide some intriguing
insights into how firms may be able to foster higher firm
performance using innovation ambidexterity to do so.
Understanding how to manage the paradoxes that crop
up in organizations has vexed management researchers
for many years (March, 1991). Our results lend support to
the notion that a learning capability may be one way of
effectively managing at least one of the paradoxes of
organization life—how to foster exploitation and exploration activities simultaneously thus generating innovation ambidexterity. By combining two practices that
facilitate internal learning and external partnering with a
third practice—an open culture, organizations are apparently able to overcome the barriers that so often arise in
sharing knowledge and fostering learning. Doing so
seemingly has the follow-on effect of simultaneously
stimulating explorative and exploitative activities that
lead to more effectively generating incremental and
radical innovation simultaneously.
Further, when practices are combined, the combination creates properties that exist only as a consequence of
the individual practices being part of the whole. And
these properties, in turn, create outcomes that are unavailable in their absence (Colbert, 2004). While an open
organizational culture, in and of itself, does have a positive influence on the simultaneous generation of incremental and radical innovation (see Model 3), its effect is
less strong than the combined practices of intraorganizational learning and interorganizational partnering (Model
4). Similarly, the effect of the combination of these two
practices is not as strong as the combination of the three
practices (i.e., learning capability). These results suggest
that innovation ambidexterity is fostered most effectively
through the interaction of these three practices as
opposed to only one or two. Apparently, building an open
organizational culture provides the impetus for individuals to engage in collaborative behaviors that are needed to
foster incremental and radical innovation simultaneously.
Once cultural values have been infused into the members
of the organization, they motivate individuals to engage
in collaborative behaviors in terms of intraorganizational
learning and partnering with other organizations. In this
way, these practices need to work interdependently with
each other in order to become a capability that has the
potential to provide competitive advantage for the organization over time. In this sense, a learning capability
represents a means for organizations to create sustained
competitive advantage. Stated differently, while a particular practice may provide some utility for generating
IA, it is when all three practices are combined together
that they become a sustainable organizational capability
(Leonard-Barton, 1992) that fosters the generation of
incremental and radical innovation (Gupta et al., 2006).
The idea of a learning capability is in line with the
notion of higher level capabilities (cf. Collis, 1994; Danneels, 2002; Gibson and Birkinshaw, 2004). Prior
research has proposed that creating combinations of practices enables organizations to avoid the inability of their
current practices to enhance innovation (Danneels, 2002;
March, 1991), thus suggesting that a learning capability
is a higher level capability that goes beyond the separate
practices of external partnering, learning among employees, and organizational culture.
Potentially, this finding has important implications for
managers in general and for managers in our sampled
industries in particular. It suggests relatively specifically
which levers they need to pull in order to overcome the
conflicts and competition that arise in developing two
different types of innovations. Building an open culture
appears to have an impact on developing not only radical
new products but also on incremental ones. Knowledge
gained and integrated is not inherently or naturally
divided according to its utility in developing breakthrough innovations versus line extensions. Oftentimes,
where an idea will lead is not knowable in advance. But
MANAGING THE EXPLOITATION/EXPLORATION PARADOX
what is known is that sharing those ideas increases the
likelihood that the idea will grow and blossom into an
innovation of some sort.
Clearly, more work is needed to understand more thoroughly what is going on here. How does an open culture
influence the circulation of ideas and knowledge coming
from both external as well as internal sources? What is
the process by which this takes place? What does it look
like? These are questions that require further inquiry.
Our findings also provide additional insight into the
debate about the value of achieving high levels of incremental and radical innovation, versus a balance between
the two, as well as the debate about achieving both types
of innovation simultaneously versus sequentially. Within
the context of Taiwanese SBUs, it appears that achieving
simultaneously high levels of both types of innovation
has a significant impact on a firm’s performance. In
short, high on both is better than balanced, and simultaneous is better than sequential. The implications of this
finding are profound. It suggests that those firms that are
able to achieve high levels of both incremental and
radical innovation by effectively combining the appropriate set of practices will have a substantial competitive
advantage, while those firms that are less capable of
doing so will find themselves at distinct competitive
disadvantage.
It will be interesting and important for future research
to investigate the ease with which the combining process
takes place and over what time period so that a sense of
the sustainability of this advantage may be obtained. It
will also be important to identify other combinations of
practices that may also provide advantage. While this
study has identified one important combination, it is
unlikely to be the only important one.
This research has also been an attempt to peek inside
the black box of relationships among a firm’s capabilities,
innovation ambidexterity, and performance. This study
has done so by examining the possibility that innovation
ambidexterity plays a mediating role between a learning
capability and performance. The results suggest that it
does. It is innovation ambidexterity and not the firm’s
learning capability itself that has the most direct and
significant impact on business performance. From a
managerial perspective, affecting business performance
requires identifying and developing a very specific capability that will result in innovation ambidexterity. Our
findings also suggest that separate practices or pairs of
practices are less effective in stimulating innovation
ambidexterity than is the combination of all three practices. Apparently, the learning capability that results from
this combination enables the organization to acquire
J PROD INNOV MANAG
2013;30(2):262–278
275
information from sources that are external to the firm and
foster learning within it while providing the motivation
for individuals to share their acquired knowledge. Our
results also suggest that shared learning may be induced
through a variety of means including fostering mutual
trust and respect among employees, as well as risktaking.
It is also important to point out that these results may
be contextually derived. The sample is of SBUs in
innovation-focused Taiwanese industries. This raises the
question of their generalizability to larger organizations,
as well as ones in other industries and countries. Taiwan
is an emerging economy with deep ties culturally and
historically to mainland China. As such, it is influenced
by the Confucian tradition and Chinese way of thinking.
It is thus interesting to speculate on whether what this
study found in Taiwanese firms could be expected to hold
for firms in more developed economies, in Western countries, or in companies in China. Research relating to
country culture indicates that Taiwan is group versus
individual oriented. That is, it values collective action
over individual action. Does this group orientation have
an impact on an organization’s ability to combine the
three practices that have been examined or on the ability
to create an open culture that promotes risk-taking and
sharing across the organization? These are questions that
require additional research.
Limitations and Future Research
While this study is limited as a consequence of our
having investigated only a few practices and indicators
of business performance, it makes a strong argument for
the importance of taking a “fine-grained” approach in
order to understand more deeply and accurately how
practices create capabilities that influence ambidexterity
and business performance. It points to the need for
future research to investigate multiple practices, types of
innovation, and different indicators of business performance, within the same study. For example, an important extension of this study would be to examine more
systematically a broader array of practices and contextual factors in an effort to understand how they help
create innovation ambidexterity.
This study is also limited by the sampling method
within highly innovative industries. While the hypotheses
were supported in the contextual setting of these innovative industries, our sample constrains the generalizability
of these findings to other industries. Future research
investigating an even greater array of industries, varying
even more than those in our sample in terms of business
276
J PROD INNOV MANAG
2013;30(2):262–278
environment, would be another important extension of
this study.
Additionally, in order to determine whether our findings hold in other contexts, it is important to replicate this
study in other industries and in the other countries,
including developed and emerging economies.
