Research On Risk Pre-warning And Aversion System Of PPP Project Of ZT Infrastructure Enterprise

The Public-Private Partnership model(hereinafter referred to as PPP model)is an important tool for playing the decisive role of the market in the allocation of resources and better serving the functions of the government in the field of public goods and services.The PPP model can combine the policy guidance and service functions of the government with the funds,management and technology of social capital,thus effectively improving the quality and efficiency of public goods and service.However,at the same time,PPP projects have large investment amounts,long construction and operation cycles,and involve multiple interests with government departments,social capital and third-party consulting agencies,which can easily lead PPP projects to certain risks such as broken capital chains and increased costs.It will make PPP model projects fail to achieve the expected results and ultimately harm the interests of multiple participating parties.As our country continues to attach importance to the public infrastructure construction sector,the development of the PPP model has ushered in a critical period.To ensure the smooth implementation of PPP projects,it is essential to control the risks in the projects.Based on relevant theoretical research,this paper identifies risk factors in the whole lifecycle of PPP projects through a case study of a PPP project of a large infrastructure enterprise,namely ZT,establishes a risk evaluation index system.Using hierarchical analysis and fuzzy comprehensive appraisal,a risk assessment model has been constructed for the project,and the identified risk factors based on expert questionnaires have been evaluated.This research concludes that the three risk factors,that is,governmental risks,constructional risks and operational risks take high risks.Therefore,these risks need to be prevented in the process of project implementation.
