Abstract： In order to improve the project benefit, how to choose a suitable supplier selection has received more and more attention of managers. But the existing supplier selection mechanism is lack of pertinence, defects exist. Based on the study of many scholars at home and abroad research results, the mechanism of supplier of hydropower engineering mechanical and electrical equipment general contracting mode.Then, by using the G1- entropy of subjective and objective combination weighting of every index in the index system of supplier selection and hydropower engineering mechanical and electrical equipment general contracting mode, build a supplier evaluation model based on grey relational analysis, calculation of each supplier grey relevancy ranking results, according to the correlation degree comprehensive evaluation of Hydropower Engineering mechanical and electrical equipment in many potential suppliers.The validity and feasibility of the model are verified by the case analysis of the supplier selection under the model of the electrical and mechanical equipment total contract.
