The expert scoring method is used to determine the weight of each index, and finally the comprehensive benefit of contract enterprise energy management is obtained. The results show that the contract energy management business has a huge driving effect on economic, social and environmental benefits. The value-added service of contract energy management has better comprehensive benefits.
