The research covers audit fees’ composition and determinant, the fee charging strategy(mainly the low-balling problem)and the relationship between audit fees and quality.The author believes to summarize and analyze the outcome of the research on American CPAs’ audit fees will help China’s CPA profession take part in the international competition and promote China’s CPAs to provide transnational auditing services.Meanwhile,it will facilitate related departments to supervise and regulate audit fees charged by accounting firms.展开更多
