Research On Risk Identification And Sharing Of Urban RailTransit PPP Project

The development of urban economy has made the demand for urban rail transit increasing.The scale of urban rail transit in China is also expanding rapidly.The construction and operation of urban rail transit projects need to invest a lot of money.In order to link the financial pressure and ensure the quality of the project,the use of PPP mode to finance and manage urban rail transit has become a priority for many local governments.Urban rail transit project has a long cycle and large investment.Therefore,how to identify risks effectively and achieve reasonable risk sharing among participants is the key to success or failure of PPP projects.Harbin Metro Line 2 has adopted the PPP financing mode,with a total investment of200 billion yuan.The risks of the PPP project are characterized by long-term,phased and discrepancy,and involve many principal players.There are complex principal-agent relationships.By combing the difference and risk factors of urban rail transit projects by using the checklist method,this paper combines the actual situation of Harbin Metro Line 2 project,establishes the project risk check list of Harbin Metro Line 2,and calculates the 2-line item of Harbin subway through fault tree analysis and comprehensive empowerment method.The main risk sharing main body of Harbin Metro Line 2 is Harbin municipal government and China Electric Power fourteen.By constructing the project risk sharing model,this paper points out that in order to realize the better sharing of project risks between the two sides,it is necessary to ensure the timely and open information,the dynamic adjustment of the proportion of risk sharing and the formulation of the necessary rewards and punishments System.
