[摘　要]　首先建立了一个包含20个风险因素的国际PPP项目风险系统，然后采用解释结构模型（ISM）分析法对这一系统进行分析，建立了一个能够清晰描述各个风险间影响关系的风险系统结构模型，并指出项目参与方在实际风险管理中不同阶层应该着重关注的风险因素。

Abstract:  In this article, a risk system of international PPP project containing 20 risk factors is set up firstly, and then interpretative structural modeling(ISM) analysis method is used to analyze the system above. According to the research, a risk system structural model which focuses on the relations among all the 20 risk factors, especially on the hierarchy of them is established. At the end of this article, the risks worth noting particularly for project participators during different phases are pointed out based on the findings when considering both direct and indirect relationships.

Key words: Public and Private Project (PPP); Interpretative Structural Modeling (ISM); risk factor; system structural analysis
