Under the background of the "Belt and Road" policy, more and more power companies are trying to improve their competitiveness through cooperation with overseas companies. Due to the complexity of the operating environment of international projects, power companies often face greater risks in external cooperation. Therefore, it's of great significance for the cooperation of International power companies to analyze the risk factors of international power engineering projects and their degree of impact. On the basis of identifying the risk factors of international power engineering projects, this paper uses the expert scoring method to determine the degree of influence on risk factors. It constructs the interpretation of structural model of project risk factors and divides the levels of hierarchical risk factors, and then it assigns weights to risk factors at the same level. This paper combines qualitative and quantitative analysis methods to determine the degree of impact of different risk factors on the project, so that enterprises can strengthen the risk perception in international development, and provide a theoretical basis for enterprises to effectively avoid risk factors.
