Risk Research Of Social Capital Caused By Government In PPP Project Based On Gray Theory

With the development of society,especially the modernization of China and the requirements of urbanization,to a large extent,China's current infrastructure construction capacity cannot meet the requirement of the state and residents,especially in water conservancy,roads,public building,Large investment is a serious shortage of productivity.The emergence of the PPP model is a good solution to this dilemma,led by the government to introduce social capital,and then the two sides jointly set up a project company and complete the project construction together,according to their respective characteristics of reasonable arrangements for the role and division of labor.However,in recent years,the development of PPP projects in China has also exposed a lot of problems,focusing on the way of social capital and government cooperation and trust.In China's previous PPP projects,there have been many times the government lost the letter caused by serious loss of social capital situation.Therefore,in order to study the government's risks to social capital in the PPP project,this article will study the impact of government action on social capital from a micro-perspective and will further analyze the risk using the quantitative method.The healthy development of the project in the future is of great significance.The article mainly completes the following work:(1)Introduced the concept of PPP mode and the necessity and importance of its development in our country through extensive reading of literature and materials,and then conducted its status and role on the two important roles of government and social capital in PPP project Detailed elaboration,pave the way for the back of the risk analysis.(2)On the basis of analyzing the development of domestic and foreign PPP models,this paper analyzes the concept of social capital,and on the basis of the risk analysis of PPP project itself,puts forward that the government should focus on the risks to social capital,Build risk assessment index system,and use the subjective and objective combination of weighting method to determine the weight of each indicator.(3)Introduced several commonly used risk assessment models,and pointed out the establishment steps of various models.Based on the applicability analysis,the optimal risk assessment model based on gray theory was selected to analyze the latter scenario.(4)Introduce the project example of this typical PPP project of Caofeidian seawater desalination project,analyze the main sources of risk and level of risk caused by the government to social capital in this PPP project,and put forward some suggestions that the government should Take risk management measures.The main conclusions of this paper are as follows: 1.Based on a large number of domestic and foreign literature and practical investigation,The risk assessment index system of social capital cased by government in PPP project is analyzed in detail;2.The use of the combination of weighting method on the PPP project in the government of social capital generated by the risk assessment indicators were empowered to diagnose the PPP project in the government of social capital generated And then through the introduction of gray clustering theory,the risk assessment model based on gray clustering method is established,and the comprehensive evaluation of the project evaluation data is provided,which provides a quick and effective risk assessment Method for social capital,but also the smooth implementation of the PPP project plays an important role.
