本研究主要在檢測海外投資程度高的公司,是否會增加聘任規模較大會計師事務所擔任查核者的需求,其查核會計師是否會傾向出具非標準式無保留意見,也研究海外投資程度是否增加資訊透明度與會計師專精程度。採用台灣上市櫃公司為樣本,實證發現當公司海外投資程度愈高,需要有更有規模會計師事務所的會計師來查核,因此公司會傾向聘任聲譽較佳會計師事務所(四大會計師事務所),以強化公司的監督,為查核品質增添可靠性。此外,當公司海外投資程度愈高,亦會加重會計師查核工作的困難度,使會計師設定較低的審計意見修正門檻,也就是較不傾向出具標準式無保留意見。再者,當企業海外投資程度越高,越使投資者需要較多的資訊揭露,也因為自利的行為,公司會選擇較不專精會計師,來進行投機行為。
The primary objective of this study is to investigate the impact of corporate foreign direct investment (FDI) on audit quality, audit opinion, information transparency and the degree of auditor’s industrial specialization. Using a sample drawn from Taiwan listed company, we find that the firms with greater FDI are more likely to employ Big four CPA firms and their auditors are less likely to issue a standard un-qualification audit opinion. Also, we find that the firms with greater FDI have higher information transparency. However, the degree of auditor’s industrial specialization will be decrease. Corporate FDI is measured by three different ways, the ratio of foreign assets to total assets, foreign operational country scope, and the numbers of foreign investees, can get the same results.
