Research On Risk Allocation Of PPP Urban Infrastructure Project Based On Game Theory

In the development of city,urban infrastructure is a indispensable important constituent,it's the material guarantee of urbanization.The model of PPP can be a good solution to the problem of insufficient urban infrastructure construction fund,it can improve the operational efficiency of the project by combing the planning,organizing,coordinating ability of government department and advanced technology,high quality effectively of private sector.However,PPP urban infrastructure have the characteristic of big investment scale,lots of project participants,long time of construction and operation cycle,complicated technology,plenty of uncertainty factors and so on,which makes PPP urban infrastructure facing more complex risk factors than some general projects.It's the key to the success of PPP urban infrastructure whether the risk can be fair and reasonable shared,so the research on risk allocation of PPP urban infrastructure project has certain practical significant.In the actual PPP urban infrastructure project,the process of risk allocation is generally shared between government department and private sector for the first,and then after the project company set up,the risk allocated to private sector is shared again among the participant in the project company.Taking this situating into consideration,this article chooses government department,private investors,general contractor and operators as the main body of risk allocation,in the process of risk allocation,studying the risk allocation between government department and private investors at first,and then studying the risk allocated to private investors at the first round shared among private investors,general contractor and operators in the project company.On the content arrangement of whole article,this article puts forward the research ideas and research methods through summarizing and analyzing the domestic and foreign research situation about the PPP project risk allocation firstly,and then expounds the related theory knowledge in writing including the PPP mode theory,Game Theory,the theory of risk sharing and some other theory secondly,combing out the risk actors in the PPP urban infrastructure in using the method of document frequency by analyzing a number of authoritative literature reading thirdly,determining the risk is shared by both government department and private investors or one of them in using the Delphi method,and using the bargaining Game Method based on risk preference to determine the proportion of government department and private investors about the risk shared by both government department and private investors fourthly,then using the method of tripartite Game Theory to make sure the risk allocation proportion respectively among private investors,general contractor and operators in the project company of the risk which is allocated to private investors at the first round,at last applying the model in a certain example.
