| In order to solve the increasingly serious public transport problems,subway has gradually become a hot spot in the construction of major cities.However,the huge cost of subway construction projects has brought huge financial challenges to the government.The contradiction between the demand for funds and the lack of funds for subway construction has become a major obstacle to the construction of subway projects.At present,the funding source of QD subway project is mainly limited to the government’s financial allocation,bank loans,etc.It has serious limitations,which limits the return rate of funds,but also hinders the development of the subway project to a certain extent.Therefore,on the basis of the mature PPP mode at home and abroad,taking QD metro line N as an example,this paper studies the risk management of PPP mode,finds out the main problems in the process of metro project and analyzes the risks in depth,so as to reduce the risk of metro project.This is of theoretical and practical significance to ensure the healthy and normal operation of subway construction.In this paper,through literature analysis method and qualitative methods of quantitative analysis,with metro line N project as an example,combined with the actual situation of this project,the PPP mode,the paper analyzes the theory of risk management,and compares the evaluation method of risk management options,and by applying the method of risk checklist WBS and RBS to QD metro line N the PPP pattern recognition,the risk of QD analysis summarizes the PPP mode risk of metro line N listing;According to its attributes,the project risk is mainly divided into nine aspects:political factor risk,financial factor risk,legal factor risk,metro construction factor risk,metro project later operation risk,market operation risk,participant credit risk,environmental protection risk and natural factor risk.On this basis,the risk assessment index system of metro line N was established by effectively combining the actual characteristics of QD metro line N with the PPP risk assessment of QD metro line N.Ahp and grey relational analysis are used to construct the risk assessment model of metro line N,and the effective assessment of different types of risks of PPP project of QD metro line N is completed.Based on the results of risk assessment,the risk indexes of the late operation risk,the risk of factors of subway construction,the risk of political factors,the risk of credit of participants,the risk of environmental protection and the risk of natural factors are relatively small,and corresponding countermeasures are put forward.The risk indicators of market operation risk,financial factor risk and legalfactor risk are relatively large,which are the main influencing risk factors in the project of metro line N.In the market at the same time,financial,legal aspects of the three-level index factors of risk: market,industry competitive,the risk of subway project supporting facilities,and other aspects of government to limit risk,inflation,interest rates in a certain change,exchange rate changes permissions change big,subway project construction,the change of the legal policy,put forward the corresponding scientific and reasonable improvement measures,effectively reduce the happening of the risk and loss,ensure the smooth implementation of the metro line N.This article embarks from the practical engineering problems,and through the QD metro line N effective the PPP project risk identification,risk assessment and risk control,to explore the effective measures of risk management problems,ensure the standardization of risk management,ensure the smooth operation of the metro line N projects at the same time,for the other similar project management of metro construction project provides a certain reference. |
