| Under the background of new-type urbanization,the central government has explicitly proposed popularizing the application of PPP model and that promoting the Cooperation between government and social capital in the project of Infrastructure construction,in order to solve the problem that shortage of local government financial cannot meet the increasingly need of public products and services.PPP is public-private partnership,it is an effective way to provide public products and services through the establishment of a partnership between government and social capital.The purpose is to use the power of the social capital financing for public project.And PPP can also promote the transformation of government functions and system innovation,expand the investment channels of social capital,and enhance the endogenous driving force of economic growth.PPP is mainly applicable to the infrastructure projects which are responsible for government and are suitable for market operation.The infrastructure projects include construction and operation of the municipal facilities such as supply of gas and electricity and water and heating,disposal of sewage and garbage.And construction and operation of the transport infrastructure such as highway and railway and airport and rail transit.And public service such as medical care and tourism and education and nursing.Even the project about resource exploitation and environmental protection.The successful implementation of PPP project is focused on finding an effective way of risk sharing and benefit distribution between government and social capital.Based on the study of literature and cases,the main reasons that most PPP projects failed are high risk and low income of social capital.Therefore,government and social capital sharing risk and benefit reasonably become the most important problem in theoretical and practical research of PPP model.The paper is based on the study of the relevant literature at home and abroad.First,elaborate the theoretical basis of the PPP such as PPP’s concept and classification and the theoretical foundation of PPP project in the park.Secondly,clarify the organizational structure,operation process,rights and obligations of the government and social capital of the PPP project in industrial park.Thirdly,discuss the model of risk sharing and benefit distribution of PPP project in industrial park,main risks and risk sharing frame and sources of benefits and benefit distribution pattern.Fourthly,analyze the process of risk sharing and the results of income distribution by using game theory.A bargaining model under asymmetric condition of government and social capital’s status is established to find the optimal solution for the proportion of risk sharing,The dynamic game model is established to find the optimal solution of the project’s total income level and its effort level when the public and social capital pursue the maximization of individual utility and overall utility,and the proportion of income distribution between public and social capital when the public and social capital pursue the maximization of individual utility.Finally,summarize the conclusion of this paper and propose the corresponding suggestions according to the research of this paper,which can provide reference for the optimization of income distribution of PPP projects in industrial park. |
