Abstract: As an important component of internal governance, the organization form of accounting firms has great influence on its survival and development. Taking four domestic accounting firms that took the lead in completion of restructuring with the qualification of H share auditing as the samples, this paper conducts an empirical study of the effect of the restructuring of accounting firms on auditing fee. The study finds that the auditing fee has been significantly increased since the restructuring of accounting firms. Further study reveals that in the key account auditing market, the restructuring of accounting firms has little influence on auditing fee; while in the minor client market, after the restructuring the auditing fee has been increased significantly. The results show that the restructuring of accounting firms contributes to standardizing the auditing fee in the independent auditing market and reducing the malignant price competition, which is of positive significance for the sustainable healthy development of the accounting firms and the profession of CPA.
