Abstract: By analyzing of process flow and energy flow and using of the energy input-output model,an energy consumption analyzing method for cigarette enterprise was developed,which included categorization of products indexes,tabulating of energy input-output and calculating of various evaluation indexes.Basing on its data of energy and material consumption,the energy utilization of a cigarette enterprise was analyzed with the developed method,and the direct and total consumption coefficients,direct and total comprehensive energy consumption of energy products and non-energy products in production process were obtained,which was of practical use for examining,evaluating and predicating the energy consumption in cigarette production process.
