Study On The Impact Of Risk Allocation,Market Environment And Economic Environment On PPP Project Investment Amount And Chance Of Success

Infrastructure projects are the basis for the normal operation of the social economy,and they are also a necessary condition for the orderly implementation of the economy and the effective guarantee of the people's living standards.Both developed and developing countries are generally concerned about the development of infrastructure.How to provide high-quality infrastructure public services and make them not only maintain the social welfare attributes,but also properly introduce market mechanisms to improve profitability and project efficiency is a topic of common concern in countries around the world.Under this background,social capital has gradually entered the field of infrastructure investment,and the PPP model(Public-Private-Partnership)is an effective attempt by the government departments of various countries in the field of infrastructure service project construction.The main research object of this paper is the success or failure of PPP project investment amount and PPP project.First of all,through introducing the relevant concepts and development history of PPP,the relevant theoretical basis will be elaborated.Then based on the existing research results and deficiencies,the difference between investment scale and investment outcome,PPP project and non-PPP The four perspectives of project differences,economic development level,market size,and project risk sharing mechanism put forward the research hypothesis.By constructing a model for empirical analysis and comparing the differences between the investment scale of PPP projects and the success or failure of subsequent projects,the differences in the influencing factors at the initial stage of the project and the subsequent implementation stage are discussed.Finally,according to the research results,the countermeasures and suggestions are proposed from four perspectives:market environment,government functions,risk allocation mechanism,and regional differences,in order to promote the long-term scientific development of the PPP model.The research results show that:(1)The level of economic development has played an active role in both the investment amount of PPP projects and the success or failure of PPP projects.A good economic environment will help attract more investment in PPP projects and provide stability for the successful completion of PPP projects.Economic environment.(2)Foreign social capital parties are bold in entering the infrastructure construction field,but the risk allocation mechanism still has an important impact on the ultimate success of the project.The excessive risk of social capital is not conducive to the final outcome of the project.In contrast,China's social capital that participates in PPP project investment is more cautious.(3)World data shows that market factors have different impacts on project investment and project success or failure.Among them,project investment focuses more on the impact of population size in the region,and the success or failure of the project focuses more on the impact of household consumption ability factors.Data in our country shows that the more people in the project area are,the higher the project investment is,and the regions with higher consumption levels tend to attract more investment in PPP projects.
