Abstract: This paper investigates the impacts of the corporate social responsibility (CSR) on trade credit financing using domestic listed firms from 2004 to 2013 from the view of the monetary policy changes through Tobit regression approach. Our results indicate that compared with firms with low quality of the CSR, firms with high quality of the CSR are more likely to obtain more trade credit. Especially during monetary contracting periods when firm obtains less trade credit financing, high quality CSR help firms to obtain more trade credit financing, and these results hold after we control the endogeneity. This paper extends the literature about the research of interaction relationship between macroeconomic and micro enterprise behavior, and also enriches the trade credit as a substitute for intuitional finance.
