China state - owned economic monopoly industry reform is initiated and private capital begins to enter the industry. But it is difficult to break the monopoly. The traditional situation of the monopoly should be broken by reforming. In competitive industry, the reorganization of state - owned assets is being processed but is difficult and should continue in order to seek reasonable distribution of state - owned capital. State-owned enterprise system reform has three points such as big state-owned enterprise shareholder reform, completeness of company management structure and approaches for enterprises to run society. As for state- owned assets supervision management system reform, central and provincial state - owned assets supervision management departments have been established. "State -owned Capital Management Companies" mode between China State - owned Assets Committee and enterprises is processed. "Investing role" of state-owned capital needs to be rationalized. We should not only establish and complete state-owned assets supervision management system of industrial and commercial enterprises but also establish and complete supervision management system of state - owned financial assets, non - business assets and natural resources assets.
