【摘要】：本文以95个有代表性的资源型城市2004—2013年的数据为样本,重点关注城市经济发展、人口增长和空间扩张几个方面,考虑能耗强度、经济规模、人口密度、辖区面积四个因素,利用LMDI法对资源型城市的能耗增长进行因素分解,并针对不同区位、不同规模与不同发展阶段三种情况分别进行资源型城市能耗增长影响因素的差异分析。得出了研究结论:总体来看,对资源型城市能耗增长影响较大的因素是能耗强度与经济规模,其中能耗强度下降对能耗增长有明显的抑制作用,经济规模扩大对能耗增长有明显的推动作用,但能耗强度下降的抑制作用不足以抵减经济规模扩大的推动作用,导致能耗总量增加。人口密度增加和辖区面积扩大对城市能耗增长的贡献率较小,都只是微弱的推动作用。单个城市能耗增长的因素分解结果与总体情况较为一致,但不同城市之间存在差异。分区位看,越是落后地区,能耗强度下降对能耗增长的抑制作用以及经济规模扩大对能耗的拉动作用越强;分规模看,小城市的落后产能改进空间还没有得到充分利用;分资源开发阶段看,衰退型城市落后产能改进成效突出但能源利用效率依然较低,成熟型城市对落后产能改进空间的利用不足。最后有针对性地提出了相关政策建议:优化产业结构,转变经济增长方式,实现资源型城市从"粗放型增长"到"集约型发展"的转变;大力发展新能源,提高能源利用效率;对不同类型的资源型城市有针对性地实施节能降耗的分类指导;强化宣传教育,有效提高企业和居民的节能降耗意识。
[Abstract]:Based on the data of 95 representative resource-based cities from 2004 to 2013, this paper focuses on urban economic development, population growth and spatial expansion, considering four factors: energy intensity, economic scale, population density, area of jurisdiction. The energy consumption growth of resource-based cities is decomposed by using LMDI method, and the difference of influencing factors of energy consumption growth in resource-based cities is analyzed according to the three conditions of different location, different scale and different development stage. The conclusion is as follows: in general, the energy consumption intensity and economic scale are the major factors that affect the energy consumption growth in resource-based cities, among which the decrease of energy consumption intensity has a significant inhibitory effect on energy consumption growth. The expansion of economic scale can obviously promote the growth of energy consumption, but the inhibition of energy intensity decrease is not enough to offset the push effect of economic scale expansion, which leads to the increase of total energy consumption. The increase of population density and the expansion of the area of jurisdiction contribute less to the increase of urban energy consumption. The factor decomposition results of energy consumption increase in a single city are consistent with the overall situation, but there are differences among different cities. The more backward the area, the stronger the effect of decreasing energy consumption intensity on energy consumption growth and the pulling effect of economic scale expansion on energy consumption, and the backward productivity improvement space of small cities has not been fully utilized. In the stage of resource development, the results of backward productivity improvement in recessionary cities are outstanding, but the efficiency of energy use is still low, and the space of backward productivity improvement is underutilized in mature cities. Finally, the paper puts forward some relevant policy suggestions: optimizing the industrial structure, changing the mode of economic growth, realizing the transformation of resource-based cities from "extensive growth" to "intensive development", vigorously developing new energy sources and improving energy utilization efficiency; The classification of energy saving and consumption reduction should be carried out in different types of resource-based cities, and propaganda and education should be strengthened to effectively improve the awareness of energy saving and consumption reduction in enterprises and residents.
