Abstract: Based on the analysis and summary of traditional energy ecological footprint (EEF) method and its research progress home and abroad, a modified EEF method is proposed by combining EEF with the change of biological productive lands from a standpoint of system theory and material flow analysis, and hereby an assessment framework of energy utilization benefit (EUB) is constructed. Taking Jilin Province as an example, this paper analyzes and evaluates the EEF and EUB respectively. The results show that from 1999 to 2008, EEF per capita has increased from 0.249 hm2 to 0.524 hm2, being a significant correlation with GDP per capita in average annual growth rate (R2=0.7574, p<0.05). Among the components of EEF, the percentage of coal footprint has increased from 68.40% to 74.99%, while the percentages of footprints of oil, electricity and natural gas all decreases at different degree. Meanwhile, the intensity of EEF has decreased from 0.387?10-4 hm2/yuan to 0.221?10-4 hm2/yuan, the elastic coefficient of EEF which has increased from 0.059 to 0.558 shows an periodic fluctuation basically, and the pressure of EEF has increased from 0.348 to 0.759. It is indicated that with the improvement of energy utilization benefit in Jilin in the past 10 years, the pressure of eco-environment has been getting increasingly bigger. However, in the following several years, it is likely that the growth rate of EEF will gradually reach a low and even falling standard, and the energy utilization benefit will largely promote in a relatively long period.
