為健全公司治理及強化董事會功能,我國於2006年修訂證券交易法,正式引進獨立董事及審計委員會制度,企業可維持原雙軌制設置監察人,或選擇單軌制,即董事會下設置審計委員會以取代監察人,而審計委員會係屬於自願設置性質。因此,本研究目的係探討我國上市及上櫃公司設置審計委員會之決定因素為何,以上市櫃公司之樣本資料進行分析。Logistic迴歸模型估計結果顯示:公司規模、獨立董事人數比例及外資持股,與設置審計委員會呈現顯著正相關;而未來成長性及管理者持股比例則無顯著相關。此外,當股權偏離程度大於20%時,僅發現獨立董事人數比例與設置審計委員會成顯著正相關,公司規模、未來成長性及外資持股則無顯著相關,而管理者持股比例則呈現顯著負相關,顯示公司股權偏離程度較高時,設置審計委員會之決定因素確會受其影響。
The authorities amended the Securities Exchange Act in 2006 and introduced the independent directors and the audit committee system to achieve sound corporate governance and strengthen the functions of the Board. Enterprises can retain their original two-track system: establishing supervisors, or selecting a monorail system: establishing the Board Audit Committee under the Board to replace supervisors. The audit Committee is a voluntary establishment nature. This study attempts to examine the determinants of establishing the audit committee in publicly listed and OTC companies. The expected factors affecting a company to appoint an Audit Committee include the size of a company, future growth, foreign holders’ ownership, and managers’ percentage of shares. This study employs Logit regression model to examine the sample data from listed and OTC companies in Taiwan in 2011. The study results shows that the size of the company, the proportion of independent directors and foreign ownership have significant positive correlation with establishment of the Audit Committee whereas future growth and managerial ownership proportion don’t. The results also found that when the equity interest in the degree of deviation is greater than 20%, only the proportion of independent directors has positive correlation with establishment of the Audit committee. In this case, the size of the company, the future growth and foreign ownership had no significant correlation, while holding ratio of directors presents a significant negative correlation. Accordingly, cash-vote divergence of the company will be the influential factor to set up the audit committee.
