Evaluation of the impact of debt default and the adjustment of corporate financing policies in coastal areas is significant to understand the stamina of Chinese enterprises' transformation and development. Based on the sample of A-share listed companies in coastal provinces in 2007 and 2018, using propensity score matching and difference in difference methods, it is found that the commercial credit of enterprises will decrease significantly after bank intervention. In particular, the higher the concentration of suppliers, the greater the inhibitory effect of bank intervention on enterprise commercial credit, which means that strong suppliers are more likely to add insult to injury; and the more perfect the financial contract system, the greater the inhibitory effect of bank intervention on enterprise commercial credit, that is, the contract system strengthens the protection of the rights of bank claims. This paper provides a theoretical basis and policy reference to improve the commercial credit quality of enterprises in coastal areas.
