Abstract: With the acceleration of China’s industrialization and urbanization, the consumption of non-renewable energy resources has been increasing rapidly; the pressure posed by economic development on energy supply and environment restriction has been on the verge of the bottom-line of the balanced sustainable development. No matter in terms of the national energy safety or harmonious development of the energy-economy-environment system, to improve the consumption efficiency of the non-renewable energy resources is an inevitable choice. Under this background, this article calculates the consumption efficiency of the non-renewable energy resources in China during 1990-2009 based on C2B-DEA and super-efficiency DEA model and makes an empirical analysis with the regression model of influencing factors, namely the five major factors of industrial structure, degree of openness, urbanization process, technical progress and non-renewable energy consumption structure. The results indicate that there exists a negative correlation between the consumption efficiency of the non-renewable energy resources and such factors as the proportion of the third industry, the proportion of the total export-import volume of foreign trade, urbanization rate and the proportion of coal consumption in the composition of non-renewable energy resources; whereas between the proportion of R&D funding and the consumption efficiency of the non-renewable energy resources there exists a significant positive correlation. At present stage, to update and innovate the technology and to reduce the proportion of coal consumption are the significant ways to improve the consumption efficiency of China’s non-renewable energy resource.
