Corporate Governance Mechanisms and Their Impact on Firm Value

Abstract

This study investigates the impact of corporate governance mechanisms on firm value through a mixed-methods research design, integrating econometric modeling with qualitative inquiry. Quantitative analysis employed fixed effects and generalized method of moments estimations, while qualitative insights were drawn from interviews with directors, regulators, and institutional investors. The results demonstrate that board independence, gender diversity, and audit committee effectiveness exert significant positive effects on firm value, as measured by Tobin’s Q, return on assets, and market-to-book ratios. Conversely, ownership concentration exhibited a negative influence, indicating risks of managerial entrenchment. Mediation analysis further revealed that corporate social responsibility strengthens the link between governance and firm value, highlighting the importance of integrating sustainability practices into corporate strategies. Cross-sectional comparisons showed that governance effects vary by industry and region, with emerging markets benefiting more strongly from independent oversight, while developed economies emphasize CSR and ESG performance. Qualitative findings confirmed that cultural norms, regulatory environments, and stakeholder expectations critically shape governance effectiveness. Overall, the study concludes that robust governance mechanisms not only enhance firm performance and market valuation but also reinforce organizational legitimacy and long-term competitiveness. These findings provide important implications for corporate leaders, investors, and policymakers seeking to design governance structures that maximize sustainable value creation.
