Research On Government Risks Of Public Infrastructure PPP Project

The construction and development of public infrastructure projects play an important role in promoting regional economic development.The mode of cooperation between government and social capital,namely the PPP model,is a brand-new management method for the construction and operation of infrastructure in recent years.It has been widely used in the construction and operation of public infrastructure in China.The country has attached great importance to the top-level design and project library of PPP model.In facts,PPP model not only alleviates the financing difficulties of the government's infrastructure construction,but also increases the efficiency of infrastructure construction and operation by introducing social capital.In some way,Social capital can also use the PPP model to achieve profitability,and ultimately achieve a win-win situation between the government and social capital.However,it is still necessary to realize that the current development of China's PPP project is not completely mature,and there are some problems in the development,which is highlighted by the lack of awareness of PPP government risk management.Effective government risk management is of great significance for the long-term development of PPP projects,but China has not yet formed a complete PPP project government risk management system,and the level of risk management remains to be improved.Therefore,in order to improve the level of risk management of Chinese government in the process of participating in PPP projects,it is of long-term significance to study the risks faced by the government in the process of participating in public infrastructure PPP projects.This essay has a certain degree of innovation in research perspectives and research methods.It takes the risks faced by the government in the process of participating in the public infrastructure PPP project as the research object,and uses the combination of principal component analysis method,improved entropy method and grey correlation analysis method to determine the qualitative with the quantitative combination research method from five aspects including politics,economy,project construction,force majeure and public risk to evaluate the government risk of public infrastructure PPP project.First of all,combing and summing up the development results of PPP mode,selecting the research method of this paper,and determining the research framework.Secondly,it explains the related concepts of public infrastructure PPP project and government risk,combines public goods theory,information asymmetry theory and project risk management theory,and puts forward the connotation and research object of government infrastructure risk of public infrastructure PPP project.Repeatedly,on the basis of clarifying the concept of government risks of public infrastructure PPP projects,risk identification was conducted,and a government risk assessment system for public infrastructure PPP projects was constructed.Thirdly,use the principal component analysis method,improved entropy method and grey relational analysis method to construct a risk assessment model,select 15 typical PPP project cases for empirical analysis,and get the project comprehensive risk assessment relevance level and project risk factor importance.Then it sorts and analyzes the evaluation results.Finally,according to the empirical analysis results,it proposes some suggestions for avoiding public infrastructure PPP projects from the aspects of politics,economy,project construction and external environment.
