How Corporate Governance Reform Mediates the Impact of Audit Committee Chair Characteristics on ESG Disclosure: A Case Study of Emerging Markets

ESG Transparency Under Governance Restructuring: The Strategic Intermediation Effect of the Audit Committee Chair

In the current global capital market, Environmental, Social, and Governance (ESG) disclosure has evolved from a "soft initiative" of corporate social responsibility into a core indicator of a company's long-term sustainable competitiveness. As investor, regulatory body, and public attention on corporate social impact has soared, ensuring the quality, accuracy, and transparency of ESG information disclosure has become a governance challenge that enterprises urgently need to solve at the strategic level. Against this backdrop, the Audit Committee, as a key body for overseeing management and ensuring compliance of financial and non-financial reporting, has its members' characteristics directly determining the reliability of ESG disclosure.

This study focuses on the driving role of three core attributes of the Audit Committee Chair (ACC)—independence, expertise, and tenure—on the quality of ESG disclosure. Theoretically, an independent chair with deep professional background can effectively restrain management's manipulation of reports, reduce information asymmetry, and thus significantly enhance the authenticity and transparency of ESG disclosure. This strengthening of internal governance is the cornerstone for enterprises to fulfill social responsibilities and build stakeholder trust.

However, in rapidly evolving emerging market environments, corporate governance frameworks are often in a period of maturation and transformation. In this context, the introduction of corporate governance reforms, such as the 2017 regulatory update under Saudi Arabia's "Vision 2030" initiative, plays a crucial "mediating variable" role. These reforms not only aim to establish a more sound regulatory system but also exert stronger compliance pressure on enterprises at the institutional level, thereby raising market expectations for high-standard disclosures.

Our empirical analysis indicates that in specific emerging markets, the positive impact of corporate governance reforms on the characteristics of the Audit Committee Chair is significantly amplified. Specifically, when the market introduces strong governance reforms, a chair with independence and experience will have an even more pronounced positive effect on ESG disclosure. This suggests that optimizing the institutional environment can effectively activate the effectiveness of internal governance mechanisms, making the ACC's expertise no longer an isolated internal factor but a strategic resource deeply coupled with the macro regulatory environment.

From the perspective of resource-based view, the independence and experience of the ACC constitute the "knowledge capital" and "network capital" that enable effective supervision of complex ESG issues by the enterprise. In markets where the regulatory environment is not fully mature, the quality of this capital directly influences whether the enterprise can translate complex ESG goals into verifiable, market-credible disclosure reports. Therefore, for emerging market enterprises, promoting higher standards for the ACC and simultaneously advancing the institutional refinement of the regulatory environment is the key path to achieving sustainable development strategy.

Reconstructing Long-Term Competitiveness: ESG Disclosure as a Ticket to Capital Attraction

The quality of ESG disclosure is no longer just a compliance requirement; it has become a key strategic signal influencing a company's long-term cost of capital, attraction of international capital, and maintenance of corporate social legitimacy.## Reconstructing Long-Term Competitiveness: ESG Disclosure as a Ticket to Capital Attraction

The quality of ESG disclosure is no longer just a compliance requirement; it has become a key strategic signal influencing a company's long-term cost of capital, attracting international capital, and maintaining its social legitimacy. For companies that can ensure their ESG disclosures accurately reflect their environmental and social impact through robust internal governance structures, their premium in the capital market will be significantly enhanced. This is essentially a reconstruction of long-term competitiveness: shifting from solely pursuing short-term financial performance to building an organization and governance system resilient and driven by sustainable development.

Under the macro trend of globalization competition, multinational corporations' focus on ESG has spread from Western markets to global economies. This demands that corporate strategy must transcend regional limitations, establishing a "resilient governance model" capable of adapting to different global regulatory standards and stakeholder expectations. For emerging markets, successfully integrating global ESG standards is not just about meeting the threshold for international capital; it is a strategic move to win over international partners and top local talent by enhancing transparency and predictability. This requires companies to view governance reform as an endogenous driving force for their long-term survival and development in the global competitive landscape, rather than a mere external compliance burden.
