摘要

公司治理(corporate governance)概念一般泛指公司之管理與監控的方法。早在1930年代公司治理的概念即已出現，直到1997年亞洲金融危機發生後，這個議題才又被廣泛討論。且近來不論是國內或國外皆陸續發生管理階層舞弊而出具嚴重不實表達財務報表，主管機關及投資人皆關注盈餘是否受到管理階層的操控，影響盈餘的品質，而造成投資者的誤判。因此，為提升公司決策品質的可靠度，避免管理階層的操弄，遂將獨立董事概念引進公司。
本研究主要目的在探討我國上市上櫃公司在聘任獨立董事後，獨立董事是否能實際發揮監督公司之功能，並更進一步探討若是聘僱具專業會計背景的獨立董事，是否更能發揮獨立董事之功能，參考DeFond(2004)的研究，以Basu(1997)之盈餘報酬迴歸模式及Givoly and Hayn(2000)的應計基礎衡量模式估計盈餘保守性，觀察聘任獨立董事對盈餘保守性之影響及不同模式下結果是否有顯著差異，並進一步檢視若獨立董事具專業會計背景對盈餘保守性之影響之程度。
本研究係以2002年至2004年我國上市上櫃公司為對象，排除金融業公司、資料不齊之公司以及極端值，蒐集到2,588家上市上櫃公司，就盈餘保守性與獨立董事之關係作相關性探討。

The concept, corporate governance, refers to the way of management and governance in the corporation. It has been emerging since the early 1930’s in response to the perceived lack of effective board oversight that contributed to the poor performance problems. In 1997 there were numbers of scandals within Asian financial markets that led to severe Asian financial crises, and this concept is debated generally. Recently, no matter what countries in domestic or foreign occur that management fault and cause financial statement incorrect seriously. The authorities and the inventors concern about whether the earnings is controlled by the management and affects the quality of earnings to cause the inventors’ judgement correct. Therefore, the concept of outside directors is introduced in order to promote the reliance of the decision of the corporations.
The purpose of this study is to explore whether outside directors can develop the function to supervise corporations after corporations employ them. In advance, to explore that corporations employ outside directors with accounting expertise could develop the function to supervise corporations powerful. This study refers to the research of DeFond(2004), and measures earnings conservatism in the models of Basu(1997)and Givoly and Hayn(2000).
We find that to employ outside directors does not help corporations increase earnings conservatism, but it would be helpful to employ outside directors with accounting expertise with accounting expertise. This is because they have accounting expertise and provide corporations related suggestions. This result could help law-makers and managements to make laws and employ outside directors in the future.
