With the development of regional integrated energy system, how to comprehensively evaluate the comprehensive energy efficiency of regional integrated energy system has become a widespread concern. First, consider the change of quality in the transformation process of different energies, introduce the concept of "exergy efficiency", convert different energies through the energy quality coefficient method, and establish a comprehensive energy efficiency evaluation index including economy, energy efficiency and environment on this basis; Secondly, an improved TOPSIS is established for evaluation, the results of entropy weight method and coefficient of variation method are combined by the least square method to calculate the weight, and the distance measurement method in TOPSIS is improved by using grey correlation degree; Finally, an example is given to verify the effectiveness and feasibility of the proposed method. It can provide a certain reference value for the planning and optimal operation of the highquality regional integrated energy system in the future.
