The Optimization And Application Of PPP Evaluation System In China

The Value for Money Assessment(VFM)evaluation is an important criterion for determining whether it is appropriate to adopt the PPP model instead of the government's traditional procurement model as the project currently being implemented by the Ministry of Finance of China to judge infrastructure and public services.However,the "Regulations on Government and Social Capital Cooperation in Infrastructure and Public Services(Draft for Comment)" does not refer to VFM evaluation.This has led to intense discussion in the PPP industry about whether "China's PPP project needs VFM evaluation".Focused on the limitations of the VFM evaluation system.Therefore,it is of great theoretical value and practical significance to study the optimization and improvement methods of China's PPP value-added evaluation system.This article uses the literature analysis method to sort out and summarize the research results of domestic and foreign value for money and other related research results,and points out the necessity and feasibility of optimizing our current VFM evaluation system.The paper understands the status quo of China's current VFM evaluation system through literature analysis and interviews,and clarifies that the limitation of quantitative evaluation methods is that the selection of discount rate is not scientific enough,the quantitative accuracy of risk costs is not enough,and the proportion of risk sharing is insufficient;The limitation of the qualitative evaluation method is that the index system is not perfect,the index weight determination method is not rigorous,and the scoring standard is not standardized.Based on the above-mentioned status quo and problems,based on the quantitative evaluation method,a capital asset pricing model was proposed,combining the “risk compensation method” or “risk retention method” to determine the discount rate;and formulating the risk quantification using the formula method,using fuzzy levels.Analyze and determine the size of risk loss,use set-valued statistics to determine the probability of occurrence of risk;put forward a modified Shapley value risk sharing model to determine the proportion of risk sharing.For qualitative assessment methods,the three-tiered meaning of “value-for-money,efficiency,and effectiveness” is used as a guideline,and a project-level logical model is used to determine that a first-level indicator is three-level and second-level indicators are twelve.Qualitative evaluationindex system;puts forward that the weight of the qualitative evaluation index system is determined by using the unique reference comparative judgment method(G2-method).Taking the PPP project of standard factory building construction in L city industrial park as an example,the paper first uses the current value-for-money evaluation method to develop the VFM evaluation,and then uses the optimized and improved methods to carry out VFM evaluation again,through comparison method optimization and non-optimization.The VFM evaluation results show that the VFM evaluation results and conclusions obtained after optimization of the method are of high scientificity and accuracy.Finally,four suggestions for improving the value-added of the PPP project are proposed: further improvement of the VFM evaluation method,and strengthening third parties Evaluate regulatory efforts,improve the VFM evaluation information disclosure system,and construct a life cycle VFM evaluation mechanism.This article through the development of China's PPP value for money evaluation system optimization and application research,the proposed optimization and improvement methods,for the improvement of China's current PPP value for money evaluation system has strong reference and reference value,can make value for money The evaluation system is more scientific and standardized in the actual application process,which in turn contributes to the improvement of the PPP project decision-making mechanism.
