According to the deficiencies of the research on electricity energy efficiency evaluation method used in energy-consuming enterprises,a kind of high energy-consuming enterprises of electricity energy efficiency degree assessment method based on fuzzy set pair analysis is introduced, and providing the theoretical basis for the enterprise energy optimizing management.This paper first proposed the evaluation index system of electricity energy efficiency grade for energy-consuming enterprises,and firstly mentioned the concept of high energy-consuming enterprises electricity energy efficiency labeling.Second,the synthesis index weights are figured out by means of analytic hierarchy process and entropy method,which not only expertise but also reflects the evaluation objectivity.Finally,calculated the corresponding connection degree of each index,and the biggest confidence principle is adopted to define the enterprise level of energy efficiency.The simplicity and accuracy of the method is verified though the case analysis and results comparison .
