Abstract
This study examines how technological innovation influences firm performance through the mediating role of Environmental, Social, and Governance (ESG) engagement, and how this relationship is conditioned by institutional quality and firm nature in China. Using panel data from 3,300 listed firms (2010–2023), we apply a moderated mediation framework with subnational institutional indicators and a binary ownership classification. Quantitative results show that innovation enhances ESG engagement, which in turn improves firm performance when measured by ROA, but not by Tobin’s Q. Specifically, innovation increases Huazheng ESG scores by 2.80–2.90 units and Wind scores by 3.60–3.70 units. A one-unit rise in Huazheng scores raises ROA by 2.1%, and Wind scores by 1.5%. Mediation analysis confirms a significant indirect effect of innovation on ROA via ESG (0.052–0.114), though the effect is negative for Tobin’s Q (−0.122 to −0.319). The ESG-mediated pathway is further moderated by institutional conditions. The positive moderating effect of non-state sector development on the innovation–ESG link is stronger for SOEs, especially in regions with more developed private sectors. In contrast, factor market development and improvements in the legal-institutional environment strengthen the innovation–ESG relationship more for non-SOEs. Where property rights are better protected and resources more efficiently allocated, non-SOEs gain legitimacy and utilize resources more effectively. These findings highlight ESG as a strategic channel for converting innovation into value, shaped by institutional and organizational contexts, and contribute to sustainability strategy literature by unpacking how institutional heterogeneity and ownership identity influence ESG-aligned innovation in emerging economies.
