环境、社会责任和公司治理（ESG）的发展理念很好地契合了中国式现代化发展的要求。目前国内学者主要研究上市企业ESG与财务绩效的关系，关于商业银行的ESG表现对财务绩效的研究内容较少。基于既有文献的梳理与总结，本文选取国内16家商业银行2011—2021年的ESG评分和财务数据进行相关性分析和基准回归分析，并进行了稳健性检验，此外还研究了风险承担作为中介变量在ESG表现与财务绩效的影响关系中的中介作用。最后，本文总结研究结论，并根据结论对商业银行和监管部门提出建议。

通过研究，本文得出以下结论：（1）国内商业银行比较重视自身ESG的发展和管理，尤其重视发展公司治理，但容易忽视环境表现，ESG发展不均衡。（2）商业银行的ESG综合评分对其财务绩效有显著正向影响。（3）公司治理对于商业银行的财务绩效有显著正向影响，环境和社会责任对于商业银行的财务绩效影响不显著。（4）商业银行的风险承担在ESG表现对财务绩效的影响中发挥了部分中介作用。

本文创新地选取商业银行的ESG表现和财务绩效作为研究对象，并引入风险承担作为中介变量研究商业银行ESG表现对财务绩效的作用机制，补充了ESG与财务绩效的相关研究，为ESG的作用机制研究提供新思路，也为后续相关领域的研究提供了参考依据。

The development concept of Environmental, Social Responsibility, and Corporate Governance (ESG) aligns well with the requirements of Chinese-style modernization.Currently, domestic scholars primarily focus on studying the relationship between corporate ESG  and financial performance,with relatively limited research on the ESG of commercial banks and its impact on financial performance. Based on a review and summary of existing literature, this paper conducts correlation analysis and benchmark regression analysis on the ESG scores and financial data of 16 domestic banks from 2011 to 2021, with robustness tests conducted. Additionally, the mediating role of risk-taking as an intermediary variable in the relationship between ESG performance and financial performance is explored. Finally, the paper summarizes the research findings and provides recommendations for commercial banks and regulatory authorities based on these conclusions.

This paper draws the following conclusions: (1) Domestic commercial banks attach more importance to the development and management of their own ESG, especially emphasizing corporate governance, but tend to overlook environmental performance, resulting in uneven ESG development. (2) The comprehensive ESG score of commercial banks has a significant positive impact on their financial performance. (3) Corporate governance has a significant positive impact on the financial performance of commercial banks, while the impact of environmental and social responsibility on the financial performance of commercial banks is not significant. (4) The risk-taking of commercial banks plays a partial mediating role in the impact of ESG performance on financial performance.

This paper innovatively selects the ESG performance and financial performance of commercial banks as the research objects, and introduces risk-taking as an intermediary variable to study the mechanism of the effect of banks' ESG performance on financial performance. This supplements the research on the correlation between ESG and financial performance, providing new insights into the mechanism of ESG effects and serving as a reference basis for subsequent research in related fields.
