Research On Financing Risk Evaluation Of Urban Rail Transit Project Under PPP Model

The Public-Private-Partnership model,through the cooperation between the government and the investors,can achieve complementary advantages and share the risk,which can relieve the government financial pressure and make the project have a good economic effect.In the construction of urban rail transit,vigorously promoting the PPP mode,introducing social capital and multi-channel financing is the way to solve the financial pressure.The financing risk of urban rail transit project under the PPP model has both the characteristics of the risk of rail transit project and the potential risk of multi cooperation after the introduction of PPP model.These risks have brought great challenges to the project financing,cooperation and implementation.Therefore,under the PPP mode,what risks exist in the financing process of urban rail transit projects needs to be evaluated and dealt with in a scientific way.The H-Bahn project,as the technological innovation type urban rail transit project,will have the risk after introducing the PPP model and how to identify the significance and value of the research.This paper adopts the method of combining theory with practice.First of all,consider the basic knowledge of PPP,analyzes the risk characteristics of PPP model and urban rail transit project through the research of principal-agent theory,project risk management theory,innovation driven theory,risk interest theory and so on,studies the relationship between the theory and the evaluation object,and finds the entry point of risk identification and evaluation.Secondly,we use a variety of risk identification methods,reliability analysis,factor analysis and other means to deal with the survey data,complete the risk classification,and establish the risk evaluation system of urban rail transit.Thirdly,the advantages and disadvantages of the common risk assessment methods are analyzed,and the overall process of the project risk assessment is optimized.By introducing the Critic method,the credibility and consistency of the experts' scoring are improved and the subjective and objective fuzzy comprehensive evaluation model is established.Finally,using the evaluation model,the actual H-Bahn is applied,empirical and analyzed,and the identification results are explained,and the mutual proof with theactual project background can be used for reference and reference for the financing risk assessment of the H-Bahn project under the PPP model.
