[Abstract]:After the financial fraud case of MacSen Robbins in 1938, a series of malpractices in the financial information disclosure and audit process were gradually revealed, due to the need to standardize the audit process and clean the audit environment. The audit committee system was proposed and formally established. After 2001, with the emergence of financial fraud cases such as Enron and WorldCom, People began to attach importance to the establishment of the audit committee as a functional institution. The introduction of Sarbanes-Oxley Act symbolized that the audit committee system had formal regulations and guarantees of the written system. It also indicates that the relationship between the audit committee and the accounting firm has been regulated by law. In the theoretical literature on the audit committee system, the research on the relationship between the audit committee system and the accounting firm is the most important research direction, and has made a lot of research results. Among the results of these studies, the main focus is on two aspects of research, on the one hand, the relationship between the audit committee and the quality of audit reports. On the other hand, the relationship between the audit committee and the change of accounting firm has been studied. Except for the changes caused by the merger of the firm, the separation of the firm and the loss of audit qualification caused by the punishment of the firm by the CSRC, the reasons for the change of other accounting firms are not clear. Such abnormal changes make the credibility of the quality of audit reports of listed companies also have hidden concerns. Therefore, the factors affecting the change of accounting firms have always been the main topics studied by many scholars, and the audit committee, as the functional department of listed companies with very close relationship with accounting firms, A study from this point of view may lead to new discoveries. This paper first reviews the relevant literature on the effectiveness of audit committee and the characteristics of audit committee, and then analyzes the theoretical background of audit committee from the perspective of principal-agent theory. Finally, focusing on the four main characteristics of audit committee independence, professionalism, scale and diligence, the relationship between them and the change of accounting firm is studied. The research hypothesis of this paper is put forward. In the part of empirical research, we select the relevant data of listed companies from 2008 to 2010, establish a regression model, and use Logistic regression analysis method to verify it. The final results show that the independence, professionalism, scale and diligence of the audit committee will have a negative impact on the change of accounting firms. The research in this paper can enrich the relevant research on the influencing factors of the change of accounting firms. In the future, in the function setting of listed companies, the independence and professionalism of the audit committee can be improved through the improvement of the independence of the audit committee. Diligence and proper determination of its size promote the effective performance of its functions, reduce the change of accounting firms, and achieve the purpose of effective audit for listed companies.
