金融業董事會性別多樣性與永續金融

本研究以我國上市櫃金融業為主要研究樣本，研究期間為 2014 年至 2021 年，基於玻璃天花板與關鍵多數理論，探討金融業董事會性別多元化和企業永續性 之間的關係，觀察我國金融業董事會女性董事占比高低及達百分之二十之關鍵多 數與否，對金融業隔年之 ESG 績效及「環境」績效、「社會」績效、「公司治理」 績效所造成之影響。經由多元 Panel 迴歸模型分析之研究結果顯示，金融業女性董 事占比逾關鍵多數者，有顯著較佳的 ESG 總績效及 ESG 揭露品質，且主要源於環 境構面績效的表現;本研究進一步分析女性董事占比的調節效果，發現一旦金融業 女性董事占比逾關鍵多數，此時，隨著女性董事占比的增加，反而對企業之公司治 理構面績效造成些微負面的影響。據此，本研究建議我國金融業最適的女性董事占 比可維持於 20%以下，於性別多元化之下更可兼顧 ESG 績效之達成。

This research investigate the nexus between board gender diversity and ESG activities in financial industry based on the theories of glass ceiling and critical mass. Using panel data for Taiwan’s listed banks for the period 2014-2021 to observe the impact of the proportion of female boarders on the firm-level ESG score and individual pillar score sequentially. The research utilizes a panel multiple regression model, and the results indicate that there is significantly better overall ESG performance and ESG disclosure quality as the proportion of female directors exceeds the critical mass, mainly driven by environmental performance. Furthermore, the study examines the moderating effect of the proportion of female directors and finds that further increases in the proportion of female directors have a slight negative impact on the corporate governance performance while the proportion of female directors exceeds the critical mass. Based on these findings, the research suggests that the optimal proportion of female directors in the financial industry in Taiwan should be maintained below or at 20%. This not only promotes gender equality but also contributes to the achievement of ESG performance.
