Abstract

Based on the data of China's listed banks from 2010 to 2018, this paper uses panel data model and threshold model to examine the impact of profitability on credit risk of commercial banks. The results show that: (1) After controlling the influence of bank size, the growth rate of net profit is negatively correlated with credit risk; (2) With the same growth rate of net profit, the larger the bank scale, the smaller the credit risk. At the same time, with the decrease of the growth rate of net profit, the influence of bank size on credit risk increases; (3) When the bank scale is large enough, the growth rate of net profit is positively correlated with the credit risk of the bank. This paper discusses the interaction between bank size and profitability and credit risk, which is of guiding significance to banks’ risk management.
