摘　　要：改进传统LMDI(log-mean Divisia index)模型,定量分析了1995-2014年内蒙古能源强度变化的驱动力。结果表明:1995-2014年,内蒙古综合能源强度下降了39.41%,其中生产部门和生活部门分别贡献了92.7%和7.3%;工业对效率效应和结构效应的贡献远大于其他部门,是驱动综合能源强度下降的关键生产部门;城镇对效率效应、结构效应和劳动效率效应所做的贡献均大于乡村,是驱动综合能源强度下降的关键生活部门。内蒙古仍可把提高工业能源效率作为未来节能的重要途径,把优化产业结构作为节能的长期战略同时积极引导居民形成节能的生活方式,减缓生活能源消费的增长速度。Using an improved LMDI model, the driving forces of energy intensity changes in Inner Mongolia dur- ing 1995 -2014 were analyzed. The results showed that the aggregate energy intensity had decreased by 39.41% from 1995 to 2014, of which the productive sector and the residential sector were responsible for 92.7% and 7. 3 % respectively. Industry was a key productive sector for the reduction of aggregate energy intensity, which had contributed to the efficiency effect and the structure effect far more than other sectors. Urban was a key residen- tial sector for the decrease of aggregate energy intensity, which supported the efficiency effect, the structure effect as well as the labor efficiency more than rural. It is still an important way for aggregate energy intensity re- duction in Inner Mongolia by improving the energy efficiency of the industry; and it is a long - term strategy to reduce aggregate energy intensity by optimizing the industrial structure, as well as advocating energy - saving lif- estyle positively.
