采用DEA模型计算2000-2012年我国中部六省的能源利用效率;并基于Malmquist指数计算分析各省能源效率变化分解,通过数据分析发现:各省能源效率在进入21世纪之后经历了一定的提高,主要得益于技术的提升;各省能源效率之间有一定差异;各省的平均规模有所提高。建议将工作重点放在加快能源利用技术进步,进一步提高各省能源效率。
The DEA model was used to calculate the energy efficiency of six provinces in central China from 2000 to 2012. Based on the Malmquist index, the province’s energy efficiency change decomposition was analyzed. The data analysis showed that energy efficiency in each province experienced a certain increase after entering the 21st century, Benefit from the upgrading of technology; there is a certain difference between the provinces energy efficiency; the average size of the provinces have increased. It is suggested that the focus of work be on accelerating technological progress in energy utilization and further improving energy efficiency in all provinces.
