When Does ESG Performance Pay Off? Corporate Reputation and Firm Performance in Chinese State-Owned Enterprises

Environmental, social, and governance (ESG) performance has become an important component of corporate sustainability and responsible governance, yet its economic implications remain contested, especially in state-owned enterprises (SOEs) that are expected to balance commercial goals with broader social responsibilities. This study examines the relationship between ESG performance and firm performance in Chinese listed SOEs, with particular attention to the mediating role of corporate reputation. The results show that ESG performance is positively associated with firm performance. Corporate reputation, risk-taking, and financial constraints are identified as important transmission channels through which ESG performance affects firm outcomes. Further analysis reveals a threshold effect in the ESG–performance relationship: when corporate reputation is relatively low, ESG investment may weaken firm performance; however, once reputation exceeds a critical threshold, ESG performance significantly improves firm performance. These findings enrich the literature on corporate sustainability and ESG value creation by showing that the performance effect of ESG is conditional on reputational capital. The study also provides practical implications for managers and policymakers seeking to promote sustainable corporate transformation in state-owned enterprises.
