PPP Cooperation Mode Of Government And State-owned Enterprises In Transportation Infrastructure Projects Construction

Now China in the social transition period, the government debt crisis caused the inadequacies of the financing system and management method reform and innovation ability in the public infrastructure construction. It has affected the healthy development of China’s economic and social. PPP mode can effectively alleviate the shortage of funds for public infrastructure construction. The core of PPP mode is choosing a suitable concessionaire, but we have many problems need to be in-depth study. This paper concentrates on the collaboration patterns, social capital selection, pricing model, risk sharing, the financing model and other issues of the PPP mode.Through understanding the concept and connotation of PPP mode, according to the user’s payment infrastructure investment project is to cover the cost of investment and whether the investors get a reasonable return, PPP mode will be divided into three main mode of cooperation, including business items, quasi operational items and non operating items. And the applicable conditions of each mode are given, an improvd AHP model for partner selection is proposed, which lays the theoretical foundation for the construction of transportation infrastructure PPP project pricing model. On this basis, this paper study the operating project pricing game model and quasi business-non operating project pricing game model according to the game theory and the contract design-risk income equity pricing principle. And the pricing model of value for money is discussed, and calibration coefficient of the model as well as solving method is given. Following an example, the proposed method is verified.Choosing appropriate social capital and building an effective decision-making system is very important for the quality assurance of infrastructure projects. According to the the level of each participant’s satisfaction within decision-making group, the evaluation metrix is determined and the corresponding weight is assessed through the SVD approach. Then using the iterative method and the principle, the algorithm and the scheme of the public private partnership selection of multi objective group decision-making in the PPP project are designed, which can obtain the optimal solution under the multi objective group decision. The symbol of completing the cooperation between the government and the social capital is the completion of the work of risk sharing. Through the study of the main risks in all aspects of the PPP project, the main risks of the parties to deal with. Then, according to the risk allocation problem of PPP mode, the general principle of risk allocation is given, and the process structure of risk allocation is constructed.One of the important factors that influence the risk is the number of financing. Therefore, it is an important way to solve the high debt ratio of enterprises to innovate financial capital model and leverage effect of financial market. Among them, the main research of the financing lease and industrial investment fund two kinds of financing models. According to the characteristics of traffic infrastructure, the paper gives the conditions of the financing lease and industrial investment fund.
