本文主要探討權益薪酬對審計委員會監督關係人交易效果之影響。本研究從美國證券交易所公開資訊EDGAR資料庫以手動蒐集關係人交易資訊，以2010年至2013年間之中小企業為樣本進行實證分析。實證結果發現關係人交易與權益薪酬交乘項與企業價值呈現顯著負相關，意即發放權益薪酬使得審計委員會極大化個人利益而過度注重短期財務績效，選擇默許管理階層不當之關係人交易安排，進而造成企業價值不利之影響。額外分析亦指出審計委員會之權益薪酬對其監督關係人交易效果有負面影響，但未發現證據指出審計委員會之現金薪酬與其監督關係人交易效果有關聯性。 / This study investigates whether equity-based compensation for audit committee members is associated with the effectiveness of their supervision on related party transactions. We hand collect the data of related party transactions for small and medium-size firms from EDGAR database for the period 2010-2013. We find that the interaction effect between related party transactions and stock compensation for audit committee members is negatively associated with firm value. It suggests that in order to maximize short-term benefits, audit committee members with stock compensation are inclined to be more tolerable to earnings management through related party transactions that are unfavorable to shareholders. Additionally, we do not find any evidence indicating that cash compensation is associated with the effectiveness of audit committee’s oversight on related party transactions.

本文主要研究支付給審計委員會較多的權益薪酬會不會影響到審計委員會的獨立性，從而支付較低的審計公費，選擇非產業專家的會計師。以2007至2015年間美國的上市公司為樣本，本研究發現審計委員會獲得的權益薪酬與審計公費，產業專家的會計師選擇呈負相關。此結果與預期一致，權益薪酬會誘導審計委員會妥協獨立性，從而買較少，品質較低的審計服務。
