One of the biggest problems that an enterprise needs to reform is that its property rights belong to the state, which results in the contradiction of the personalization of state-owned enterprise operations. As a result, corporate managers are not responsible for the enterprise. It is difficult for enterprises to achieve economic benefits. In the reform, state-owned enterprises Began to face the market, and the government also gave other full autonomy, but this has also led some state-owned enterprise executives to strengthen insider control, making state-owned enterprises a corrupt channel for some people to fake public funds. The public capital absorbed through the shareholding reform is due to the strength is weak and it is impossible to check and balance this effect. Obviously, after the establishment of the mixed ownership model. If the insider control mechanism of the state-owned enterprise has not been changed, its effect can only be limited. The text is intended to emphasize:. ['Depersonalization of operations makes it difficult for state-owned enterprises to achieve economic benefits.', 'Mixed ownership model can effectively promote the reform of state-owned enterprises.', 'Public capital forces cannot balance the insider control mechanism of state-owned enterprises.', 'Mixed ownership is the key to successful SOE management system reform.']
