The Research About Quantitative Evaluation And Risk Sharing Optimization Of The Value For Non-Operating Ppp Projects In The Decision-Making Stage

With the development of the socialist market economy and accelerating urbanization process,in order to enhance the supply capacity and efficiency of public infrastructure and public services,and to relieve the pressure of govermment financial expenditure under the new normal of our economy,we will prevent and defuse the local debt risk.The scope of social capital participation in public infrastructure and public services is expanded.The PPP(public-Private-Partnership)model project has become an important force to promote China's economic and social development.PPP as a project financing method,it has effectively improved the government's utilization of social capital and resources.In particular,the reasonable sharing of risks greatly reduces the total cost of project risk.It has effectively advanced the construction of our country's infrastructure.However,PPP projects has a large number of participants,the complexity of project construction operation and the diversity of risks make the PPP project face many obstacles and problems in the implementation process.Some local govermments deviate from the value standard of the social economy,and the concept is used to carry out PPP mode packaging or the standard evading of the feasibility study report to value the argument and risk assessment.Facts have proven that the project that lacks the value argumentation of depth is easy to have problems in the construction and operation process.The realization of the project goal will be met with some resistance.In particular,the implicit debt crisis caused by non-operational projects will increase.The value of money is not only the value of guiding the govermment to establish correct PPP orientation,but also a methodology to judge the applicability of PPP model.Whether the operation of non-operating items in PPP mode is more advantageous than traditional mode,the government department should evaluate the full value of the item in the project decision-making stage and judge the applicability of PPP mode in project construction.In this paper,the value evaluation system of the relatively mature abroad is sorted out,based on the study of the VFM quantitative evaluation method and process,combined with the feature of non-operating items and related policy in our country,chose the PSC-PPP contrast analysis VFM quantitative evaluation model,analyzed the calculation method and basic data parameter model of PSC value and PPP value in detail.The innovation point of this paper is to analyze the key factors that influence the evaluation result.The method of quantification of risk cost is given by using the method of scenario analysis and set value statistics.The feasibility and applicability of the quantitative evaluation model for non-operating PPP project are verified through the case analysis of the PPP project in the museum of Qingzhou city,and provide scientific decision-making basis for government departments.Finally,the risk sharing of the case project is optimized.The weight of 27 risk factors in the scheme is calculated by using AHP method and the risk prevention measures are proposed,which has strong practical guidance significance.
