摘要


由於金融風暴之發生,掀起企業普遍存在資訊透明度不足的問題,導致投資大眾對企業財務報告的不信任。而台灣發展出資訊揭露評鑑系統,對各公司做評比,並依此公布國內上市櫃公司之資訊揭露透明度。本研究即以此分數為資訊透明度之代理變數,採用多元迴歸模型進行分析企業資訊透明度對當期報酬與未來盈餘間關聯之影響,並延伸討論此關聯是否會受到企業的經營型態(家族與專業經理人)及公司治理良劣有所差異。樣本期間考慮2008年金融風暴之影響,選取其前後兩年之全體台灣上市櫃公司為研究對象,實證結果發現只要公司願意提升其資訊透明度,不管是在家族或專業經理人之經營型態所產生的不同代理問題或是公司治理良劣差異下,都會使投資者減少投資過程所面臨的不確定性,進而將其所預期的未來盈餘訊息反映在公司當年的報酬上。表示投資者對於願意揭露資訊之企業有極大信心,即鼓勵企業應盡量揭露其營運相關訊息。
