Critical Success Factors of Infrastructure Projects under PPP Model in China

In recent years, a large number of PPP infrastructure projects have emerged in China. But various reasons have led to a low success rate of these projects. The aim of this paper is to establish critical success factors model for infrastructure projects under PPP mode and to identify the links between these factors. So this research is of important practical significance to improve the success rate of PPP projects. On the basis of reviewing relevant researches of project critical success factors, this paper proposed forty-five success factors of infrastructure projects under PPP mode and found out twenty-one critical success factors among them through questionnaire survey and statistical analysis. Then the relationship between these twenty-one factors was analyzed by applying system engineering method and an interpretative structural model with six layer of recursive structure was established. The practical study in the last part showed that five factors can affect the realization of other success factors and are of especial importance. And these five factors should be the focus of future research.
