Abstract
The present study examined how the multi-country green technology co-patenting network structure evolved from 1997 to 2016. For that purpose, we used Social Network Analysis tools, which allowed us to assess the network structure from a visual and quantitative perspective. The results indicate that the network expanded as the number of participating countries and ties increased. In all periods, the network grew significantly centralized around a small group of countries, in which the U.S., Great Britain, Germany, France, and Canada had paramount weight. Emerging countries like India and China also stood out due to their growth over time, as they eventually managed to gain central positions in the network. Other developing countries remained marginal, such as Brazil.
