Based on the experience from other countries, within the well-established legal system, the national model, private model, and the public-private partnership model could all become the operation approach to the public enterprises. Therefore, we shall dedicate ourselves to the construction of public enterprises with a comprehensive model, which is an integration of the state-owned model, public-private model and private-owned model with the state-owned and the public-private models mainly included. In the process of constructing the comprehensive model, the public interest shall be guaranteed, for the core of the public enterprise is in the feature of providing public goods and services instead of the ownership. Besides, competitive neutrality shall be kept as the foundation so as to attract private capital to the supplying of public goods and services. Finally, in the comprehensive model construction, laws and regulations should serve as the guarantee, because only when the law is put into force can the reform be carried out with good reason.
