Too much of a good thing? Exploring the curvilinear relationship between environmental, social, and governance and corporate financial performance

The effect of environmental, social, and governance (ESG) activities on corporate financial performance (CFP) could be linear or nonlinear. However, inconsistent results remain a research gap and thus need to be re-examined. By drawing on stakeholder theory and the neoclassical economics perspective while using the panel data of 155 Chinese listed firms from 2010 to 2020, system generalized method of moments (GMM) estimation results revealed an inverted U-shaped relationship between ESG and CFP. Moreover, by drawing on the institutional-based view, it was determined that government subsidies moderate the inverted U-shaped relationship between ESG and CFP. Specifically, we found that the inverted U-shaped effect of ESG on CFP is weakened when government subsidies are high. This study contributes to the literature by confirming the presence of a curvilinear relationship between ESG and CFP. This study also generates meaningful implications suggesting that the governmental role in ESG is salient in mitigating associated financial costs for firms, thereby ultimately affecting CFP.
