Abstract: Taking 381 commercial Banks from 2007 to 2017 as samples, this paper studies the cyclical and regulatory effectiveness of credit behavior. The research shows that there is pro-cyclical credit behavior of commercial banks in China, but large banks and joint-stock banks have stronger pro-cyclicality. With the increase of capital adequacy ratio, the pro-cyclical effect of bank credit is weakened, which shows the effectiveness of counter-cyclical regulation. For regulators, different types of banks should be treated differently, and different measures should be taken. At the same time, the regulation of capital adequacy rate should be strengthened in the economic cycle, reasonable capital adequacy rate standards should be set up, and the concept of supervision to prevent systemic financial risks should be established.

Key words: credit behavior, procyclicality, supervise
