As global focus persists on gender variety and corporate social responsibility, the participation and influence of women in corporate governance, particularly their effect on the environmental, social, and governance (ESG) performance of corporations, have garnered extensive scrutiny. Studies have shown that women usually exhibit a more prudent approach to risk. In corporations with decision-making and tend to care more about long-term corporate interests and social responsibilities, the presence of women in executive roles confers a distinctive edge in enhancing a firm's ESG outcomes. This study explores the influence of women directors' personal characteristics on performance in ESG corporations and the findings suggest that the proportion of female directors has a significant positive impact on the ESG performance of Chinese technology companies. Furthermore, the corporate risk appetite has a positive moderating effect on the relationship between the proportion of female directors and ESG performance. The higher education that female directors get, financial professional background, and long-term experience can more effectively promote the company's ESG performance. This study enhances the theoretical framework of corporate governance and ESG studies, while also offering innovative guidance for firms to enhance their ESG scores and develop effective risk management strategies.
