| In the current era of increasingly severe environmental pollution,promoting sustainable economic development has become an inevitable move.Since the reform and opening up,China’s economy has achieved explosive growth,but this development method that sacrifices resources and environment is not sustainable.However,the implementation results of environmental protection policies indicate that relying solely on the constraints of environmental protection systems is not enough to reverse the current pollution behavior of high polluting and high-energy consuming enterprises.In this context,China has successively formulated a number of green finance policies to support enterprises to carry out green reform.As the core of green finance policies,green credit is an important means of support.Therefore,green credit plays a crucial role in the critical period of China’s current economic transformation and future economic development.However,as the main body implementing green credit,commercial banks not only undertake the task of fulfilling national policies,but also achieve the development goal of enterprise economic profits.Therefore,how to achieve the healthy development of green credit business in commercial banks is of great significance.To study this issue,this article selects financial data from 19 listed commercial banks in China from 2010 to 2021 as the research sample,selects green credit balance as the core explanatory variable,and introduces the quadratic term of green credit balance to explore whether carrying out green credit business will affect the performance level of banks through two channels:credit risk and interest income,and from the perspective of asset size Heterogeneity analysis is conducted on the relationship between ownership nature and social responsibility rating at three levels.The empirical results indicate that a certain scale of green credit will increase the non-performing loan ratio of commercial banks,increase their credit risks,squeeze out existing high interest rate traditional credit,and cause interest income losses,which is not conducive to the development of commercial banks.But with the continuous expansion of green credit scale,restricting the loan balance of high pollution and high energy consumption enterprises and diverting funds into low-risk green environmental protection projects can help improve the asset structure of banks,suppress the rise of non-performing loan rates,increase interest income of banks,and ultimately contribute to the improvement of business performance of commercial banks.Based on the above empirical conclusions,this article proposes corresponding policy recommendations from the perspectives of government,enterprises,and commercial banks to promote the high-quality development of green credit business in commercial banks. |
