摘要：基于超效率DEA方法对我国能源效率进行了分析，发现改革开放以来我国能源效率经历了“下降—上升—下降—上升”的波浪式变化过程，而且在今后一段时间内还会继续提高。根据能源效率影响因素逻辑关系分析将技术进步和结构调整确定为能源效率关键影响因素，在此基础上，对改革开放以来技术进步、结构调整与我国能源效率的关系进行了计量分析。实证考察了专利授权数、第三产业产值比重、天然气消费比重和水电消费比重对我国能源效率的影响，并提出了我国能源效率改进对策。

Abstract: Energy efficiencies in China are analyzed based on the super-efficiency DEA, and the result shows that energy efficiencies in China have a down-up-down-up wavy-like change process since reform and open policy, and it will continue to improve in the near future. According to a logical relation analysis on influencing factors for the energy efficiency, technical progress and structure adjustment are determined as key influencing factors of energy efficiency, on basis of which, an econometric analysis between energy efficiencies in China and technical progress, structure adjustment since reform and open policy is conducted. The effects of patent authorization quantity, percentage of output value of tertiary industry in GDP, natural gas consumption proportion in energy consumption structure, and hydropower consumption proportion in energy consumption structure imposed on the energy efficiencies in China are empirically investigated, and improvement countermeasures of energy efficiencies in China are put forward.
