The inverted U-shaped relationship between corporate social responsibility and default risk: The role of financing constraints.

With increased corporate liquidity and debt repayment pressure, CSR's "insurance" role has received more attention. We conducted a comprehensive empirical analysis of 4988 listed companies in the Chinese context during 2011-2020. Our research has three findings: First, the initial increase in CSR will lead to a rise in default risk. However, once the CSR level exceeds a specific threshold, the default risk decreases as the CSR rises. We tested the robustness of the results by replacing the explanatory and the explained variables and taking into account the lag time effect, which proved the reliability of our research conclusions. Second, the mediation analysis shows financing constraints play an important mediating role in this inverted U-shaped relationship. On the left side of the U-shape, CSR performance intensifies financing constraints, while on the right side, increasing CSR reduces financing constraints. Finally, we confirm heterogeneity in the impact of CSR on the default risk of different enterprises' ownership and size. Our study complements the current literature on the effects of CSR on default risk. We are making policymakers and stakeholders aware of the importance of mandatory CSR disclosure.
