摘要

我國公開發行公司自2007年1月起適用新修訂之證券交易法，應擇一設置審計委員會或監察人，正式將審計委員會制度引進。過去文獻指出，較頻繁的審計委員會會議可提升財務報導與審計品質，降低重大內部控制缺失發生機率，及減緩管理當局與利害關係人間的代理問題。審計委員會勤勞度(diligent)是審計委員會品質一項重要信號指標，本文參考過去文獻使用審計委員會開會次數做為衡量審計委員會勤勞度之代理變數。
本研究旨在探討我國上市櫃公司審計委員會開會次數之決定因素，將影響審計委員會開會次數之決定因素，區分為公司特性、代理成本、董事會特性及審計委員會特性四大方面進行探討。蒐集2007年至2011年已設置審計委員會之上市櫃公司為研究樣本，透過波爾松迴歸模型(Poisson regression model)分析影響審計委員會開會次數的因素。實證結果顯示，當公司規模愈大、公司發生虧損情形、董事長兼任總經理、董事會開會頻率愈高，及審計委員會財務或會計專家比率愈高的公司，審計委員會開會次數也愈多。而當公司內部股東持股比率愈高情況下，審計委員會開會次數有顯著降低。

The mechanism of audit committee has been introduced into Taiwan since January 2007. Domestic public company applies to the newly revised Securities and Exchange Act that should set up an audit committee or a supervisor. Prior research indicates that more frequent audit committee meetings are associated with reduced incidence of significant internal control weakness, the agency problems between management authorities and stakeholders, and improve the quality of financial reporting and auditing. The audit committee diligence is an important signal of the quality of the audit committee indicators. This study uses the number of audit committee meetings as the proxy for the diligence of audit committees.
In this study, we examine the determinants of the frequency of audit committee meetings in Taiwan. The determinants of domestic public companies are divided into four main categories, including the factor of the corporate characteristics, agency costs, the board of directors and audit committee characteristics. The sample comprised of domestic public companies that formed audit committee from 2007 to 2011. We used the Poisson regression model to examine the determinants of the frequency of audit committee meetings. The empirical results implicate that larger firms, the company incurred a loss situation, CEO duality, board meeting frequency is higher, and the proportion of audit committee financial experts are positively associated with audit committee meeting frequency. Audit committee meeting frequency is negatively associated with the proportion of insider ownership.
