Abstract: This paper expands the study of trade credit financing to economic policy uncertainty level,and studies the trade credit financing behavior from the perspective of accounting conservatism. Research shows that the higher the accounting conservatism, the more trade credit financing the company obtains; when the economic policy uncertainty is high, the positive relationship between accounting conservatism and trade credit financing becomes stronger; further study finds that state-owned property right and legal environment play a regulatory role in the relationship between accounting conservatism and trade credit financing: state-owned property right negatively regulates the relationship between accounting conservatism and trade credit financing, while legal environment positively moderates the relationship between accounting conservatism and trade credit financing. Research conclusion suggests that conservative financial report supports companies to improve trade credit financing under the environment of economic policy uncertainty.

Key words: accounting conservatism, economic policy uncertainty, trade credit financing
