Samples were divided into international, large, medium-sized and small accounting firms, based on which the empirical analysis was conducted by regression model. The findings are as follows. 1. The overall performance of international accounting firms has no significant difference before and after the Act; Service is not significantly correlated to Performance; the cross-product term shows that there is no significant difference on the correlation between Service and Performance before and after the Act. 2. The overall performance of large accounting firms after the Act is worse than that before the Act; Service is positively correlated to Performance; the cross-product term shows the correlation degree between Service and Performance after the Act is higher than that before the Act. 3. The overall performance of medium-sized accounting firms after the Act is significantly better than that before the Act; Service is positively correlated to Performance; the cross-product term shows the correlation degree between Service and Performance after the Act is lower than that before the Act. 4. The overall performance of small accounting firms after the Act is significantly worse than that before the Act; Service is positively correlated to Performance; the cross-product term shows the correlation degree between Service and Performance after the Act is lower than that before the Act. 5. There is no significant difference on the Performance of international accounting firms allying with consulting firms before and after the Act; the alliance Service is not significantly correlated to the alliance Performance; the cross-product term shows the correlation degree between the alliance Service and Performance of the accounting firms after the Act is higher than that before the Act. 6. The Performance of large accounting firms allying with consulting firms after the Act is significantly worse than that before the Act; the alliance Service is positively correlated to alliance Performance; the cross-product term shows the correlation degree between alliance Service and alliance Performance of the accounting firms after the Act is higher. 7.
