Research On Infrastructure Project Risk Management Under PPP Mode

PPP(Public Private Partnerships)is a new type of public-private partnership that can be applied to infrastructure projects.The traditional financing model has many shortcomings,such as lack of funds in the public sector,long life cycle of cost recovery,large investment risks,and inefficient management of functional departments.Public-private partnerships not only overcome the above-mentioned defects,but also increase the financing channels for the private sector and enable them to obtain certain economic benefits.The reason why the public-private partnership model can be introduced by infrastructure projects is that the public-private partnership model is continuously used in practice.Second,people's demand for infrastructure is greater than supply.Therefore,the public-private partnership model achieves mutual benefit and win-win results between the public sector and the private sector.However,the development of China's public-private partnership model is not mature enough,and risk management is critical to the overall infrastructure construction and the realization of public-private partnership projects.Public and private sectors need to carry out objective risk identification,risk assessment,and risk response to infrastructure public-private partnership projects.Therefore,relevant departments must strengthen the risk management of infrastructure public-private partnership projects in order to facilitate the smooth progress of this project.This article starts from the theoretical basis of project financing of PPP model,introduces the connotation and operation mode of PPP model,and the basic connotation of infrastructure project financing and related risk management theory.Secondly,on the basis of theoretical research and summarization of infrastructure PPP projects implemented at home and abroad,the risks identified in the financing of infrastructure projects under the PPP model are identified and summarized,and AHP and comprehensive fuzzy evaluation are combined to perform risk assessment.The construction of the model.Finally,this thesis has been verified through a PPP project of highway reconstruction and expansion project,identified 9 risk factors of the 9 categories of the project,constructed the risk assessment index system of the project,and the level analysis and synthesis fuzzy The combination of evaluation and risk assessment resulted in the overall risk level of the project being low,and the importance of the risk factors of the project was ranked.Among them,investment and financing and financial risk,operation and maintenance risk,and construction risk ranked in the top three.According to the principle of risk sharing,risk sharing of risk factors in the project was carried out,and specific response measures were put forward for each risk factor.
