本研究是探討上市櫃公司是否應強制設立勞工董事，監督獨立董事確實執行監督公司治理與履行企業社會責任（Corporate SocialResponsibility，簡稱CSR）。本研究樣本採用2010至2014年天下雜誌之「企業公民Top50」公司，並且利用台灣經濟新報（TEJ）資料庫，搜集公司治理變數與勞工董事相關資訊。實證結果指出勞工董事可以提升公司治理成效，發現公司規模愈大監督效果愈好；而對於董事長兼總經理雙重職務與獨立董事的職責監督愈好。最後，結果也顯示勞工董事對於公司治理與CSR間會有正向干擾效果，表示透過勞工董事的有助於監督企業公司治理與提高履行CSR的成效。因此，可提供管理當局修法參考，建議對於上市櫃公司應強制設立勞工董事，以強化公司治理、增進CSR與勞工福利，有效解決台灣勞工低薪與社會安全的問題。
