世界各國為推動或強化公司治理，均已設立或推動獨立董事與設置審計委員會為發展重點。由於近年的審計委員會之文獻都以探討審計委員會設置與盈餘品質間的管理居多，本研究以公司Tobin^'' s Q為衡量公司價值之指標，探討設置獨立董事與審計委員會對公司經營績效之影響。進而探討董監投保責任險以及審計委員會兼任薪酬委員會對公司經營績效的影響。 本研究採用最小平方法分析獨立董事與設置審計委員會對公司經營績效影響，實證結果顯示，設置獨立董事制度者，公司經營績效比較好。但由於設立審計委員會制度，目前尚未普遍，因此審計委員會制度與公司績效影響不顯著。公司對董監投保責任險者，與公司經營績效呈現高度正相關。審計委員會兼任薪酬委員會，亦因設置審計委員會與尚未普及因此與公司營績效無顯著相關。 Establishing independent director and audit committee is an important developmental orientation of corporate governance in the world.
