At present

food production factories in our country evaluate energy consumption level by using energy consumption per unit production or energy consumption fees. However

these indices do not reflect the influence of the using level

business level

and the quality level on the enterprise energy efficiency. In this study

energy consumption situation of some food production factories at home and abroad were compared

and the problems caused by the current energy consumption evaluation indices were analyzed. A new energy efficiency evaluation index which can reflect using level

business level

and the quality level was proposed. Then the evaluation of energy efficiency for six representative domestic food production factories was performed with the present index. The result shows that energy efficiency difference among factories is obvious.
