This paper is examines the relation between agency costs and the turnover of internal audit manager (henceforth IAM), and further explore whether firm attributes, such as managerial ownership, and dual chairman/CEO structure, external audit firm switching, influence that relationship. In reference to Singh and Davidson Ⅲ(2003) and Ang, Cole and Lin(2000), this paper use the operating expense ratio and asset turnover ratio as the proxies for agency costs. By using Logit regression analysis, this study finds that the turnover of IAM is not only significantly correlation with agency costs but also managerial ownership. Furthermore the results show that the corporate governance factors, like external audit firm switch and turnover of the mangers, are positively associated with IAM turnover.
