This study elucidates the interrelationships among corporate governance disclosure index (CORPGOVDISCIN), bank sustainability characteristics (BSCs), bank-based climate change initiatives (BCCIs) and financial performance (FP) through the lens of multi-theoretical framework. Based on a panel dataset of 2785 observations (220 banks) from 16 Sub-Saharan Africa countries between 2007 and 2022, we observe that bank sustainability reporting framework (BSRF) and board sustainability committee (BSCOM) are positively related to increased levels of BCCIs. Second, the study shows that the BSRF-BCCIs and BSCOM-BCCIs associations are positively moderated by CORPGOVDISCIN, indicating that these relationships are contingent on the quality of the bank's corporate governance mechanisms. Third, the study then provides evidence that BSCOM is positively related to FP, but BSRF has no effect on FP. Fourth, we also observe that BCCIs disclosure has positive impact on FP, but actual BCCIs investments do not seem to improve FP. Fifth, the study detects that the association between BCCIs and FP is significantly moderated by CG mechanisms. We identify CG disclosure as the possible channel through which BCCIs and FP are interlinked. Finally, we show that the predicted relationships vary across banks' operating periods. Our findings are robust to endogeneity and selection bias concerns.

银行可持续性、气候变化举措和财务绩效：公司治理的作用


本研究通过多理论框架的视角，阐明了公司治理披露指数（CORRPGOVDISCIN）、银行可持续特征（BSC）、银行气候变化举措（BCCI）和财务绩效（FP）之间的相互关系。根据 2007 年至 2022 年间来自 16 个撒哈拉以南非洲国家的 2785 个观察结果（220 家银行）的面板数据集，我们观察到银行可持续发展报告框架 (BSRF) 和董事会可持续发展委员会 (BSCOM) 与 BCCI 水平的增加呈正相关。其次，研究表明 BSRF-BCCI 和 BSCOM-BCCI 关联受到 CORPGOVDISCIN 的积极调节，表明这些关系取决于银行公司治理机制的质量。第三，研究随后提供了BSCOM与FP正相关的证据，但BSRF对FP没有影响。第四，我们还观察到BCCI的披露对FP有积极影响，但BCCI的实际投资似乎并没有改善FP。第五，研究发现 BCCI 和 FP 之间的关联受到 CG 机制的显着调节。我们认为企业治理披露是 BCCI 和 FP 相互关联的可能渠道。最后，我们表明预测的关系在不同银行的运营期间有所不同。我们的研究结果对于内生性和选择偏差的担忧是稳健的。
