| During the 13th Five-Year Plan period,the state issued a series of policies to support the construction of public rental housing in affordable housing.However,public rental housing construction projects have problems such as high construction cost,long capital utilization period,and slow investment recovery rate,which have brought greater financial pressure to the local government.The introduction of PPP(Public-Private-Partncrship,hercinafter referred to as "PPP")model for the construction of public rental housing can not only ease the government’s financial pressure,but also improve the efficiency of the project’s public services.In the public rental housing PPP construction project,the reasonable risk sharing of the government,social capital and other participants is the core of the project’s implementation and long-term operation,and it is also one of the hot topics of current research.This article takes the public rental housing PPP construction project as the research object,on the basis of analyzing the project risk related theory,identifies and analyzes the project risk,based on the bargaining game model to reasonably share the risks of the government and the private sector,and finally empirical analysis.The research results are as follows:(1)Proposed the risk identification and evaluation method of public rental housing PPP construction projects.Based on the checklist method and questionnaire survey method,the risks of public rental PPP projects are identified,selected,and classified,and the risk evaluation index system of the project is summarized,including:6 first-level risk factor indicators and 40 second-level risk factor indicators.The fuzzy analytic hierarchy process(FAHP)was used to determine the weight and establish the evaluation set,and constructed a public rental PPP construction project risk evaluation model.(2)Constructed a game model of public rental housing PPP project construction risk sharing.Through analysis of government stakeholders,private sector and other project stakeholders in the public rental housing PPP project,combined with the degree of risk preference of project participants,the risks among the project entities were initially shared,and the risk-bearing methods were discussed.Based on the bargaining game model with incomplete information,the Hassani transformation theory is brought into the model and solved,and according to the model results,the proportion of project risk sharing and the degree of influence required by the game players are finally obtained.(3)Empirical analysis was conducted on a PPP construction project of a talent rental housing construction in Xi’an.Based on the risk evaluation model constructed above,the project risk score is 3.361,and the degree of risk is general risk.According to the risk appetite analysis,it is concluded that the proportion of independent commitment and joint commitment in the 40 risk indicators of the project are 3:1.Through the game model calculation,the risk sharing ratio of the two parties in the 10 shared risks is calculated,and then the optimal ratio of each risk sharing of the project is analyzed.Finally,based on the results of risk evaluation and risk sharing,the risk of public rental housing PPP construction projects is proposed.Management measures and recommendations. |
