新式查核報告中最重要的變革之一,為審計查核準則公報58號「查核報告中關鍵查核事項之溝通」。本文以查核報告中有提及稅務相關之關鍵查核事項者,作為企業是否進行租稅管理之判斷依據來衡量本研究之應變數,考量公司治理同時影響管理者對稅務管理與績效管理決策,故採用彷彿無相關迴歸作為計量方法。本文以2016年至2020年上市(櫃)公司為研究樣本,實證發現在以董事會規模作為公司治理代理變數時,公司治理對避稅程度之影響為顯著正向。另一方面,採用不同之公司治理代理變數時,公司治理對績效之影響方向並不一致。表示公司治理與績效存在一定之關係,而其影響方向則視以何種面向去進行分析。
One of the most important changes is Statement on Auditing Standards No. 58, " Key Audit Matters ". The purpose of this study was to assess that how the new auditor’s report affects tax administration. The key audit matters relate to taxation mentioned in the audit report are used as the basis for judging whether the enterprise conducts to measure the dependent variable in this study. Since corporate governance affects managers' decisions on both tax management and performance management, this study adopted Seemingly Irrelevant Regression (SUR) as our empirical model. A sample of listed (or over-the-counter (OTC)) companies in Taiwan in 2016 and 2020 was selected to investigate this issue. The result of the empirical data is that the effect of corporate governance on tax avoidance is significantly positive when board size is used as a proxy variable for corporate governance. In addition, the direction of the effect of corporate governance on performance is not consistent when different proxy variables of corporate governance are used. In summary, there is a particular relationship between corporate governance and corporate performance. The direction of influence depends on different aspects.
