摘要

由於2006 年國內證券交易法修正後，公司始得以全體獨立董事組成審計委員會取代監察人制度。本研究透過2007 年至2010 年上市櫃公司的樣本，探究審計委員會設置及其特性對公司績效與資訊揭露品質的影響。實證結果發現設置審計委員會公司之市場績效、資訊揭露品質優於未設置者。在審計委員會特性方面，審計委員會人數愈多，愈能提昇市場績效與資訊透明度。審計委員成員兼任其他公司獨立董事的比率愈高，愈能提出專業見解，提升公司資訊揭露品質，但對於市場績效則無顯著影響力。

After the enactment of Securities Exchange Act of 2006, the publicly listed companies could establish an audit committee to replace their supervisors. By selecting samples from publicly listed firms from 2007 to 2010, this study aimed to explore the impact of the establishment and characteristics of an audit committee on firm performance and information disclosure quality. The empirical results show that firms with audit committee have better market performance and information disclosure quality than firms without audit committee. In addition, firms with more audit committee members have better market performance and higher level of information transparency. The more audit committee members holding several directorships concurrently, the better expertise they can offer to enhance information disclosure quality. However, it is not significantly related to market performance.
