Study On PPP Model Evaluation Of Urban Rail Transit

In recent years,because of the serious traffic problems,China’s urban rail transit developing rapidly.As of the end of 2017,34 cities in China’s interior have completed rail transit lines of 5021.7 kilometers.It is expected that by 2020,the total mileage of urban rail transit operations in China will reach 6,000 kilometers.On the other hand,the construction of rail transit requires large funds and high operating costs,making it impossible for government departments with limited financial capabilities to meet the increasing traffic demand.The PPP model is a kind of investment and financing model for cooperation between the government and social capital.It can provide public services while maximizing public and private resource sharing and effective capital turnover.It is the first choice for investment and financing of urban rail transit construction.In the process of the introduction of urban rail transit in PPP mode,the profit model,income distribution,risk sharing and other indicators are strongly concerned by the government and social capital.Therefore,it is particularly important to analyze the profit model,income distribution,risk sharing and other indicators of the PPP model applied to urban rail transit projects.This article adopts the detailed analysis methods of literature analysis,comparative study,case study,analytic hierarchy process(AHP)and fuzzy comprehensive evaluation.The main research content is the specific implementation effect of combining the PPP model with urban rail transit projects.In order to enhance the credibility of the study,three different PPP modes are compared in the specific analysis,namely PPP mode,BT mode and BOT mode.Different types of urban rail transit cases were selected for each model,namely Beijing Metro Line 4,Beijing Olympics Olympic Line,and Shenzhen Metro Line 4 Phase II.By collating and summarizing the three specific projects,the existing urban rail transit PPP projects and BT and BOT projects are compared and analyzed in multiple directions;and using the analytic hierarchy process and fuzzy comprehensive evaluation theory,an index evaluation system is established.The two theories complement each other and complement each other to specifically analyze the impact of the profit model,income distribution,and risk sharing on the three financing models(PPP model,BOT model,and BT model).According to theanalysis results,the PPP model is applied to urban rail transit.The rectification measures and PPP model are more suitable for the conclusion of urban rail transit.At the end,a summary of the entire discourse analysis was made,combined with the current status of the use of the urban rail transit PPP model in China,and suggestions and opinions were provided for reference.
