绿色信贷政策会提高商业银行风险承担吗?——基于中国31家上市商业银行的准自然实验

Green Credit Policy Will Increase the Risk Taking of Commercial Banks:A Quasi-natural Experiment Based on 31 Listed Commercial Banks in China

探究绿色信贷政策的实施如何影响商业银行风险承担的问题,对防范、化解银行风险具有重要意义。本研究以2008—2022年中国商业银行年度数据为样本,通过构建双重差分(DID)模型,探究绿色信贷政策对商业银行风险承担的影响作用及内在机制。研究发现,绿色信贷政策的实施会提高商业银行风险承担;绿色信贷政策通过提高流动性创造和贷款集中度从而提高商业银行风险承担,银行竞争在二者之间发挥负向调节作用。基于此,商业银行可以通过适度降低贷款集中度和流动性创造、引进精通绿色信贷的复合型人才;金融监管部门可以构建差异化的绿色信贷供给格局,来降低商业银行风险承担。

How the implementation of green credit policy affects the risk taking of commercial banks is of great significance for preventing and resolving bank risks.Taking the annual data of Chinese commercial banks from 2008 to 2022 as samples,this paper explores the influence and internal mechanism of green credit policies on risk taking of commercial banks by constructing a Difference-in-Differences(DID)model.The study reveals that adopting green credit policies leads to an escalation in the risk exposure of commercial banks.Green credit policy increases the risk taking of commercial banks by improving liquidity creation and loan concentration,and bank competition plays a negative regulating role between them.Based on this,commercial banks can moderately reduce the concentration of loans and liquidity creation,introduce compound talents proficient in green credit,and financial regulatory departments can build a differentiated green credit supply pattern to reduce the risk of commercial banks.
