On the basis of literature survey, this paper combines qualitative research with quantitative research to evaluate the influencing factors of expressway project risk under PPP mode. This paper starts from three parts:Firstly, starting from the current situation of expressway construction projects at home and abroad through the analysis of the advantages and disadvantages of PPP mode and three characteristics, the necessity and importance of project risk management under PPP mode are obtained. Secondly, the paper elaborates the risk of PPP project of expressway identifies the corresponding risk, and initially determines the three major factors affecting the risk of expressway project under PPP mode. Finally, according to expert judgment, the most critical factor is determined and a scientific, reasonable and effective risk factor evaluation index system is established. The index system includes three first-level indicators and six second-level indicators. On this basis, the judgment matrix is constructed by using the analytic hierarchy process, so as to form the influencing factor model. Finally, taking Fuling-Fengdu Expressway in Chongqing as an example, this paper uses the analytic hierarchy process (AHP) to carry out an empirical study on the model, in order to determine the importance of different risk factors.
