摘要

　　由於國際間近年來重大的公司財務報導不實與財務舞弊案件頻傳，造成投資人對於公司財務報表的可靠性產生嚴重質疑，亦使得公司治理機制與盈餘管理之相關議題受到各界熱烈討論。

　　本研究目的旨在探討獨立董監事特性與盈餘管理之關聯性，以2002年至2003年底有設置獨立董監事制度的671家上市上櫃公司為樣本，檢視獨立董監事之特性是否有助於獨立董監事監督功能的發揮，以抑制公司盈餘管理的程度。獨立董監事特性方面，本研究將其分為獨立性、會計財務專業能力及董監事治理經驗等三項特性，並進一步探討公司自發性的改善公司治理而自願性設置獨立董監制度的影響；盈餘管理方面，以cross-sectional modified Jones model計算出的裁決性應計項目絕對值作為衡量盈餘管理程度的代理變數。然而，部分文獻發現Modified Jones Model會有模型設定問題並產生較大裁決性應計項目的衡量誤差而造成錯誤推論，故本研究應用Kothari et al.(2005)之方法，在模型中納入調整績效因素。
本研究實證結果發現如下：
1.獨立監察人席次比率與公司盈餘管理程度呈現顯著負　相關。
2.獨立董事與獨立監察人具會計財務專業背景與公司盈　餘管理程度呈現顯著負相關。
3.獨立董事平均兼任其他公司董監事家數與公司盈餘管　理程度呈現顯著負相關。
4.自願性設置獨立董監事制度公司之盈餘管理程度較強　制性設置獨立董監事制度公司為低。
5.獨立董監事較為關切公司是否進行盈餘操縱向上，而　對於公司盈餘操縱減少之行為，是給予較少之關注。
