本研究以董監事特性為主要研究變數,探討其對企業舞弊與資訊揭露品質之影響,期能瞭解強化公司治理(董事會運作與設置審計委員會)對舞弊發生之抑制與資訊品質之提升效果。研究期間為2003年至2012年,關於舞弊樣本採用一家舞弊公司配對兩家非舞弊公司之方式進行配對,資訊揭露品質資料來源為證基會的資訊揭露評鑑系統。實證結果發現外部董事比率愈高,公司發生舞弊的機率愈低,而資訊揭露品質愈高;獨立董事具有會計或財務專長者,公司發生舞弊的機率愈低,而資訊揭露品質愈高;然而,董事會開會次數和公司設置審計委員會對舞弊發生率均無影響力,而對資訊揭露品質則有顯著負向和正向影響。本研究結果支持董事會的獨立性、勤勉度與專業性對舞弊發生率與資訊揭露品質的監督效果。
