摘要: 在环境问题与经济发展的矛盾逐渐增大的情形下，绿色金融的发展对于商业银行的重要性日益突出。因此，我国商业银行积极开展绿色信贷业务，希望通过扩大绿色信贷规模提升银行竞争力。在此背景下，本文以10家具有代表性的商业银行的数据为样本，检验了绿色信贷规模与商业银行竞争力的关系。本文还以信贷融资成本作为中介变量，探究了绿色信贷规模通过影响信贷融资成本进而对商业银行竞争力的影响机制。研究表明，绿色信贷规模增加会使得商业银行竞争力提高，其传导机理是绿色信贷规模会减少信贷融资成本，从而提高银行的竞争力。

Abstract: Under the situation that the contradiction between environmental problems and economic de-velopment is gradually increasing, the development of green finance is increasingly important for commercial banks. Therefore, commercial banks in China actively carry out green credit business, hoping to enhance their competitiveness by expanding the scale of green credit. In this context, this paper examines the relationship between the scale of green credit and the competitiveness of commercial banks using the data of 10 representative commercial banks as a sample. This paper also explores the mechanism by which green credit scale affects the competitiveness of commercial banks through influencing the cost of credit financing as a mediating variable. The study shows that an increase in green credit size leads to an increase in the competitiveness of commercial banks, and the transmission mechanism is that green credit size reduces the cost of credit financing and thus increases the competitiveness of banks.
