ESG Performance and Corporate Value in an Emerging Market: The Moderating Role of Board Structures in Sustainability

This study examines the relationship between publicly traded Thai companies’ ESG performance and value as well as how board structures moderate this. In the Thai context, there is a limited number of empirical studies that employ the board of directors’ structure as a moderating variable, despite the importance of the board’s role in corporate management. This study aims to address this research gap. A panel GMM regression model is employed to address endogeneity issues, and our sample consists of 94 Thai listed companies with available ESG data from 2019 to 2023, resulting in 470 firm-year observations. The results demonstrate positive direct impact of ESG score on corporate value. In addition, board independence is positively significant and relates to company value. However, this research found negative moderating effect of board independence on the relationship between ESG score and corporate value. Furthermore, the empirical results indicate that board size does not have a significant direct and moderate impact on corporate value. Moreover, firm size and leverage are not related to corporate value. The results confirm the agency theory and stakeholder theory. Based on the findings, company executives should integrate ESG practices into their strategic plans. Moreover, regulatory authorities should promote expertise diversity and independence within the board and promote ESG standards and disclosure, as well as offer tax incentives for companies with outstanding ESG. This would enable investors to consider ESG performance in their decision-making. This study represents a new contribution to literature, especially in the context of emerging markets.
