To better understand Africa's banks and the environment, this study investigates the impact of financial performance on environmental performance in Africa. We examined financial performance, environmental performance, and some control indicators dated from 2000 to 2016 by applying panel quantile regression and panel vector autoregressive techniques. Our results indicate that (i) in North African countries, carbon emission had a significant negative impact on financial performance on the 25th quantile and (ii) in the South, carbon emission had a statistically positive impact on financial performance on the 25th and 50th quantiles with the marginal effect increases from the lower quantile to the highest quantile. Also, bank deposits statistically negatively impacted financial performance on the 25th and 50th quantiles for both North and South economies. The dynamic panel quantile results show dissimilar effects at different quantiles. Also, the panel vector autoregressive results show that in North Africa carbon emission had a positive impact. Our results validate the stability test of the panel vector autoregressive model. The granger causality results in the North show a bilateral causal link between carbon emission and bank credit, carbon emission, and bank deposit. Since sustainability has become one of our era's most thorny issues, this paper provides extensive policy directives to assist African nations in boosting a greener future.
为了更好地了解非洲的银行和环境，本研究调查了金融绩效对非洲环境绩效的影响。我们通过应用面板分位数回归和面板向量自回归技术，考察了 2000 年至 2016 年期间的金融绩效、环境绩效和一些控制指标。研究结果表明：（i）在北非国家，碳排放对金融绩效在第 25 分位数上具有显著的负向影响；（ii）在南部地区，碳排放对金融绩效在第 25 分位数和第 50 分位数上具有统计学上的正向影响，且边际效应从低分位数到最高分位数逐渐增加。此外，银行存款对北部和南部经济体的金融绩效在第 25 分位数和第 50 分位数上均具有统计学上的负向影响。动态面板分位数结果表明，不同分位数的影响存在差异。此外，面板向量自回归结果表明，在北非地区，碳排放具有正向影响。我们的研究结果验证了面板向量自回归模型的稳定性检验。在北非的格兰杰因果关系结果表明，碳排放与银行信贷、碳排放和银行存款之间存在双向因果关系。由于可持续性已成为我们这个时代最棘手的问题之一，本文提供了广泛的政策指导，以帮助非洲国家迈向更绿色的未来。
