The invention discloses an enterprise efficiency evaluation method based on the equivalent energy saving amount, which comprises the following steps: step one, the comprehensive energy consumption per unit product is calculated; step two, the equivalent energy saving amount of per unit product is calculated; step three, the total equivalent energy saving amount of an enterprise is calculated; and step four, efficiency evaluation is performed on the enterprise. Concepts of the equivalent energy saving amount per unit product and the total energy saving amount of the enterprise are introduced, sorting or rating is performed on the efficiency level of enterprises is performed according to the size of the total equivalent energy amount of each enterprise, and cross-industry inter-enterprise efficiency evaluation is realized.
