Using data from Chinese A share listed companies from 2008 to 2019, this paper investigates the relationship between corporate executives with financial background and choice of international “Big Four” accounting firms. Results indicate that firms with higher ratio of executives with financial background are more likely to choose international “Big Four” accounting firms as their auditors. In addition, the choice of international “Big Four” implies higher auditing fees, but contributes to better accounting information quality. Moreover, corporate executives with financial background can mitigate the “premium effects” and meanwhile strengthen positive effects on accounting information quality. Further analysis suggests that the previous positive correlation between international “Big Four” and financial background is more pronounced among firms with severe type I agency problem; neither type II agency problem nor risk avoidance exerts significant moderating effects; In contrast to international “Big Four”, large domestic accounting firms, who are also capable of providing high quality auditing services, are less likely to be selected by corporate executives with financial background.
