The results show that the efficiency of newly founded joint-stock commercial banks exceeds that of state-owned commercial banks. But for the state-owned commercial banks, the efficiency increases greatly after they have undertaken property right reform, which illuminates that the property structure has significant effects on bank efficiency. 2 Through re-defining the input and output variables of commercial banks, the author establishes the input and output evaluation index system. Particularly, intermediary business revenue is introduced to the output index, which shows the strategy transition direction of China commercial banks. It provides more comprehensive information for the status of bank efficiency. 3 Applying the econometrics method, the author analyzes the influential factors of commercial banks efficiency. The regression results indicates the effects of the factors, such as the ratio between interest revenue and loan quantity, human capital quality, loan quality, market share, card business amount and the property right structure. Especially, we lay emphasis on the property right structure and finds that it has remarkable effects on bank efficiency. This provides new idea for further reform of commercial banks. 4 Through releasing the inner relation among the property right structure, market structure and banking efficiency, the author states the reform paths of China commercial banks from the theoretic perspective and analyzes the paths of China commercial banks in the practical choices. So the necessity of property right reform of the state-owned commercial banks is well explained. 5 Involving with the current status of property right reform of the state-owned commercial banks, the author analyzes the new challenges of China state-owned commercial banks after the joint-stock reform and states the direction of the further reform from the aspects of building multiple property right structure with reducing state-owned share, completing corporate governance structure and matrix-shape management frame, enforcing the strategy transition and so on.
