Capital market oversight and internal capabilities: Synergistic drivers of corporate environmental performance in emerging economies

This paper examines how financial market oversight interacts with firms’ internal capabilities to shape environmental performance, using a large panel of Chinese listed companies from 2011 to 2021. We conceptualise investor attention, analyst coverage, and media scrutiny as financial governance mechanisms that complement internal production, management, and R&D capabilities. Drawing on resource-based and institutional perspectives, extended with dynamic capabilities and ESG finance theory, we develop a framework linking capability development to sustainability outcomes through capital market channels. Empirically, we construct a multidimensional environmental performance index verified against external signals and apply fixed-effects, dynamic panel estimators, and instrumental-variable strategies to address endogeneity and reverse causality. Results show that internal capabilities significantly improve environmental performance and that financial oversight amplifies these effects, reducing information asymmetry and strengthening market discipline. Interaction tests and event-study evidence around policy shocks confirm the synergistic mechanism. Our findings highlight the role of capital markets in promoting corporate sustainability in emerging economies, offering implications for investors, analysts, and policymakers seeking to integrate ESG considerations into valuation and governance practices.
