This article examines the link between corporate social responsibility(CSR) and cost of bond(COB) in China. We find that there exists a negative relationship between CSR and COB. In particular, when the bond issuer is a state-owned enterprise, or when the credit rating of bond is high, the negative association between CSR and COB is strengthened. The findings indicate that CSR plays a significant role in reducing the risk premium of corporate bonds through an insurance-like effect. Moreover, the effect of CSR on COB also depends on contextual factors such as firm ownership and bond credit rating.
