本研究探討審計委員會、企業社會責任及企業價值間之關聯性。將研究分為兩部分：針對審計委員會及企業社會責任之關聯性，實證結果顯示，設置審計委員會之企業對於企業社會責任之影響為顯著正相關，表示審計委員會能夠監督企業之運作，使得企業投入較多的心力在企業社會責任中。另外，針對審計委員會、企業社會責任及企業價值之關聯性，實證結果顯示，企業社會責任與企業價值間為顯著正相關，然而審計委員會與企業價值間無顯著關係，表示企業投入較多心力在社會活動中，其企業價值也會相對地提高。 / The purpose of the study is to examine the connection between audit committee , corporate social responsibility (CSR) and firm’s value.The conclusions of this study are divided into two parts.
