Research on the Risk Assessment Method of PPP Project based on the Improved Matter Element Model

When identifying PPP project risks using the decomposition analysis method, the PPP project risks are considered to include government risk, market risk, and project risk. Based on these facts, a constructed list of PPP project risks is established, which can be divided into three first-class indexes and 27 second-class indexes. Based on the analysis of the traditional matter element model limitations, the evaluation model of PPP project risk assessment of the improved matter element model is established, in order to provide effective support for effective PPP project risk management, contract management and other work. Lastly, the feasibility of theoretical research is verified by a case study.
