Financing Risk Evaluation Of Transport Infra-Project Based On PPP Mode

Transportation infrastructure projects have long financing periods and large investment requirements,and cannot meet the needs of transportation construction by the government alone.By applying the PPP(Public-Private Partnership)model to transportation infrastructure projects and taking full advantage of social capital,on the one hand,it reduces the burden on the government,and on the other hand,it provides new ideas for solving financing difficulties.As a key part of the PPP project of transportation infrastructure,financing is not only related to the normal construction and implementation of the project,but also determines the success or failure of the project.Therefore,it is necessary to scientifically identify and analyze the risk problems existing in the financing of transportation infrastructure projects under the PPP mode,and to do a good job of risk response.This article studies the financing risks of transportation infrastructure projects under the PPP model by establishing an evaluation model and analyzing specific PPP projects.The specific research content is as follows:First,this article introduces the related concepts and theories of the PPP financing model,describes related theories of public product theory,risk management theory,risk-benefit theory,principal-agent,etc.,and combines the characteristics of the transportation infrastructure projects under the PPP model with reference to research objects and related theories The relationship between them is explained,which lays the foundation for the later research work.Secondly,through the literature research method to achieve the preliminary identification of risks,and sort them out,and then complete the secondary identification of risks through the expert survey method,establish a financing risk list,and establish a financing risk evaluation index system based on specific projects.Third,the comparison and selection of risk assessment methods are performed to clarify their advantages and disadvantages.The improved DHGF(Quaternion integrated algorithm)evaluation method is applied to the project financing risk evaluation in this paper,that is,the weight is determined by the weighting method of OWA(Ordered weighted average)operator based on the combination number,then the gray weight is calculated using the gray theory,and then the fuzzy comprehensive evaluation is performed.Finally,the evaluation model is applied through the X highway project,and the evaluation results are analyzed and verified with the project actuality,which verifies the rationality of the model and provides a reference for the financing risk evaluation of the transportation infrastructure PPP project.
