With the further expansion of China's "Belt and Road" initiative, the Chinese enterprises are being more and more active in the overseas market in recent years. Take the power industry for example, large number of Chinese engineering companies have developed their own systematic construction framework for different type of projects in domestic market. But challenges and problems may occur once the present domestic mode is directly applied to the international projects. And it also is the main uncertainty or risk faced by the Chinese enterprises when carrying out the international projects at present stage. Under this background, this paper takes the international electric power project under EPC mode (Engineering, Procurement and Construction) as the research object and the Interpretation Structure Model (ISM) is applied to analyze the potential risk factors which may affect the economic benefit and the social benefit during the implementation of these projects by Chinese enterprise. Through carrying out the comprehensive identification of those potential risk factors, this paper aims at providing a more visualized structure to show all kinds of potential risks and their corresponding impact mechanism for the Chinese contractors, which can reduce the risk level or the potential damages effectively when carrying out the related projects in overseas markets.
