| The PPP model is currently widely used and its operation is relatively mature,which has attracted much attention from governments around the world.The PPP model has been growing in China for a short period of time.At present,while encouraging various social capital such as state-owned holding companies,private enterprises,mixed-ownership enterprises,and foreign-invested enterprises to participate,effectively identifying and responding to the risks of PPP projects is the key issue currently.This paper conducts research on the PPP project of the Fourth Ring Road Expressway in Z City,and comprehensively explains the related concepts and risk characteristics of the PPP model.At the same time,checklist method and wbs-rbs are used to identify project risk factors.On this basis,the fuzzy comprehensive evaluation method and analytic hierarchy process is used to systematically evaluate the risk of the project,and the weight value of each risk is calculated to establish a project risk sharing scheme.Based on a fair market operating environment,a reasonable investment return mechanism,and a clear basic framework for risk allocation,the project construction,operation and management,law,and policy risks should be reasonably,effectively between government and social capital.The irrational risk sharing structure is avoided,and the ability of the project to combat risks is improved.The government and social capital also share the results of the project operation process through partnerships.In addition,based on the analysis of the background situation of the PPP project on the Fourth Ring Road Expressway in Z City,this paper studies the risk sharing scheme of the PPP model to promote the construction of very large infrastructures from the perspective of PPP risk management,and proposes some new ideas.At the same time,the project construction and the later operation proposal can continue to be used for reference in otherPPP projects. |
