This paper first proposed First, the an evaluation index system of electricity energy efficiency grade rating was established on the basis of the energy efficiency data collected by the electricity energy efficiency monitoring terminal of the high energy-consuming enterprises, and for energy-consuming enterprises,and firstly mentioned the concept of electricity energy efficiency label for high energy-consuming enterprises was introduced for the first time. electricity energy efficiency labeling. Second Then, the synthesis synthesized index weights are were figured out by means of the combination of the analytical hierarchy process and the entropy method, which not only expertise laid emphasis on expert experience but also reflects reflected objectivity of the evaluation. objectivity.
