實證結果顯示，未控制內生性問題之前，女性董事比例的提升與基層員工薪酬之間存在顯著正相關性，但與員工離職率及員工流動率無顯著關聯；當修正內生性問題之後，則基層員工薪酬、員工離職率及員工流動率皆顯著性不足，此顯著性不足結果可能來源於，所使用工具變數在本文探討的議題中參考性有限所致，或是研究區間尚未受到金管會強制規定上市櫃公司需包含至少 1 名不同性別的董事，女性董事比例相對較低，難以確認女性董事是否對員工福祉產生影響力，亦建議後續研究者，可針對2023年之後的數據作規範前與規範後的探討。;This study examines the impact of board gender diversity on employee welfare using data from Taiwan-listed companies from 2012 to 2022. Employee welfare is measured by grassroots employee compensation, employee turnover rate, and employee mobility. This paper adopts the instrumental variables approach to mitigate endogeneity issues, following relevant literature. The ratio of female directors to total directors within the same industry is the instrumental variable for robustness testing.
The empirical results indicate that before controlling for endogeneity issues, there is a significant positive correlation between the proportion of female directors and grassroots employee compensation but no significant relationship with employee turnover rate and mobility. After correcting for endogeneity issues, the significance of the effects on frontline employee compensation, employee turnover rate, and employee mobility rate diminishes. This insignificance may stem from limitations in the instrumental variables used in this study or the fact that during the study period, Taiwan′s Financial Supervisory Commission did not mandate listed companies to include at least one director of a different gender, resulting in a relatively low proportion of female directors. Therefore, it is challenging to confirm whether female directors influence employee welfare. Future research should examine data from 2023 onwards before and after regulatory changes to explore this issue further.
