This study examines the determinants of operating performance for the public accounting industry in Taiwan. Empirical data are from 1989 to 2007 Survey Report of Audit Firms in Taiwan. In terms of market segment, total samples are divided into four categories, including international, national, regional, and local audit firms. Based on the multiple regression analyses, we first have the determinants of operating performance for the four categories of audit firms. Next, we conduct Wald test to determine the ranking of the determinants obtained. Main results are as follows. In the international audit firms, the most important determinant of operating performance is size followed by the work experience of auditors. For the national audit firms, the most important determinant of operating performance is size followed sequentially by the human capital leverage, age of firms, auditors’ educational level, degree of diversification, economic factors, and work experience of auditors. The most important determinant of operating performance is still size in the regional audit firms. Age of firms ranks second and the remaining factors are degree of diversification, auditors' educational level, economic factors, and continuing professional education. As regard the local audit firms, their most important determinant of operating performance is size as well. Other determinants consist of human capital leverage, degree of diversification, continuing professional education, age of firms, auditors' educational level, and work experience of auditors.
