Research On Risk Management Of PPP Project Of Cross-Mi River Bridge In Jinguang Street,Shouguang City

In recent years,various regions are actively exploring the application of PPP(Public-Private Partnership)in urban infrastructure construction.However,due to the characteristics of many participants,long cooperation time and huge investment scale in PPP projects,the difficulties and risks of project implementation are relatively large.In order to avoid unnecessary risks for all participants,it is particularly important to take scientific and comprehensive project risk management measures as soon as possible,so it is very necessary to study and carry out risk management of PPP projects.Taking the PPP project of Cross-Mi River Bridge in Jinguang Street,Shouguang City as the research target,this paper summarizes the current research status of risk management in PPP projects both domestically and internationally,and conducts specific research from three aspects: risk identification,risk assessment,and risk response measures.In the risk management process of the project,the Checklist Analysis is used to preliminarily identify the possible risk factors,and then the Delphi is used to summarize the main risks of the project into 6 risk stages,namely,the risk in the preparation period,the risk in financing period,the risk in design period,the risk in construction period,the risk in operation period,and the risk in handover period,with a total of 31 main risk factors.On the basis of the risk identification results,a risk assessment index system for the PPP project of Cross-Mi River Bridge in Jinguang Street,Shouguang City is established.The Analytic Hierarchy Process is used to calculate the weight values of 31 main risk factors and 6 risk stages.The Grey Clustering Evaluation is used to evaluate the risk levels according to 3 levels: high,medium,and low.The risk assessment results of the project indicator layer,criterion layer,and target layer are calculated separately.The target layer,which is the overall risk assessment level of the project,is considered as a medium risk.Finally,based on the comprehensive analysis of the risk assessment results,targeted measures are proposed to address various levels of risk stages in accordance with the principles of risk sharing,risk prevention,risk reduction,risk transfer,and risk retention,in order to manage risks better.To ensure the implementation of the project,this paper carries out the risk management of the whole life cycle,and provides a case reference for the risk management of similar PPP project risk management.
