绿色信贷、银行异质性和银行财务绩效

Green Credit, Bank Heterogeneity and Bank Financial Performance

随着绿色经济的快速发展,商业银行逐步增加了绿色信贷投放力度,以期在满足绿色融资需求的同时开拓新的利润增长点。本文系统地梳理了绿色信贷对银行财务绩效的作用机制,并基于2007—2017年我国29家商业银行的数据,实证检验了绿色信贷对银行财务绩效的异质性影响。实证结果表明:绿色信贷占总贷款比重上升有助于提高商业银行的净息差;对规模较小、流动性水平较高的银行而言,绿色信贷对银行财务绩效的改善效果更强,但资本充足水平对绿色信贷和财务绩效的关系并无明显影响。本文研究为商业银行积极开展绿色信贷业务提供了经验依据,并且从鼓励中小银行发展绿色信贷、推动绿色信贷资产证券化和绿色金融债发行、降低绿色信贷风险权重等方面,为进一步推进绿色信贷发展提出了具体建议。

With the rapid development of the green economy, commercial banks gradually increase green credit to meet the demand of green financing, and exploring new profit growth points. This paper systematically reviews the functioning mechanism of green credit on banks’ financial performance and empirically tests the heterogeneous influence of green credit on the financial performance of banks based on the data of 29 commercial banks from 2007 to 2017 in China. The results show that green credit helps to increase banks’ net interest margin. For small banks and banks with high liquidity level, green credit plays a more significant role in improving their financial performance, but banks’ capital adequacy level do not affect the relationship between green credit and banks’ financial performance. This paper provides a positive empirical evidence for commercial banks to develop green credit, and proposes policy suggestions for further promoting the development of green credit, such as encouraging of small and medium-sized banks to develop green credit, promoting the securitization of green credit assets and the issuance of green financial bonds, and reducing the risk weight of green credit.
