摘要

自2001年恩隆案爆發之後，許多國家一直積極檢討和改善他們的管理制度，尤其是公司治理與資訊揭露。當有了健全的公司治理機制，企業才能在資本市場上順利的籌措資金，進而維持公司的長期競爭力與永續經營之能力。

　　本研究以證基會於2008年所發佈的『第五屆上市櫃公司資訊揭露評鑑系統』中之上市公司之資訊揭露評鑑結果進行研究，以『公司治理』構面中的獨立董事比例、機構投資人持股比率、董事長是否兼任總經理為變數；與『公司績效』構面中之資產報酬率為變數，對既有之評鑑資訊透明度之結果等級A+、A、B、C、C-進行分析。

　　實證結果顯示，公司治理與公司績效之相關變數對於資訊透明度所產生的影響中，獨立董事比例與資訊透明度呈顯著正相關、機構投資人持股比率呈顯著正相關、資產報酬率亦呈顯著正相關；惟董事長是否兼任總經理呈不顯著正相關。
