近幾年，由於國內企業之家族、集團企業特性的影響與法規制度未能切實執行，致使董事會與監察人未能發揮應有的功能，因而引進不具利害關係的獨立董事、獨立監察人、審計委員會，期以改善公司內部治理機制不佳的情形。本研究之目的，一為研究設置審計委員會，對於公司之資訊揭露程度是否具有提升之功能；二為研究設置審計委員會，對於公司之盈餘品質是否具有提升之功能。本研究以2010年之電子產業之上市上櫃公司為研究對象，樣本共601筆，再進一步將樣本分為上市公司及上櫃公司來探討，其中上市公司共313筆，上櫃公司288筆，運用多元回歸及聯立方程模型進行分析，主要實證結果顯示設置審計委員會對資訊揭露程度之影響在全部樣本及上市公司中有顯著影響；然而在上櫃公司中並無顯著影響。設置審計委員會對盈餘品質之影響在上市公司中有顯著影響；然而在全部樣本及上櫃公司中並無顯著影響。設置審計委員會與資訊揭露程度及盈餘品質之影響在上市公司中有顯著交互影響，然而在全部樣本及上櫃公司中並無顯著交互影響。
