摘要/Abstract

摘要： 本文评价与分析了辽宁省14 个地级市能源效率的空间等级与结构特征，分别从DEA能源综合技术效率、单位GDP能耗及融合二者的能源利用效率三方面来进行研究。在对各地级市产业结构高级度、合理度、集中度测度与分析的基础上，采用耦合度评价模型总结了辽宁省能源效率与产业结构的耦合特征。研究结果表明：① 辽宁省各地级市能源效率差异显著，沈阳、大连、鞍山、锦州属于高能效地区，低能效高能耗地区集中在辽西北地区与抚顺、本溪等重工业城市；② 能源综合技术效率、单位GDP能耗、能源利用效率的高能效区域分别呈现“π 型”、“二字型”、“工字型”的空间结构特征；趋势分布面上，能源利用效率自东向西呈现先上升后下降的趋势，自北向南呈现先下降后上升的趋势；经济发展的双核结构特征等因素对能源效率空间格局的形成有重要影响；③ 产业结构高级化发展水平高的地区集中在辽东南沿海城市，产业结构合理度的空间分布呈现以沈阳、大连为两极的“工字型”特征，产业结构集中度高的城市主要分布在辽中南城市群；④ 全省能源效率与产业结构整体耦合度较低，沈阳大连两极高度耦合，产业结构高级度与能源效率的耦合度相对较高。

Abstract: Taking 14 prefecture-level cities in Liaoning Province as the source of samples in the study area, this paper first explored the spatial hierarchy and structural characteristics of energy efficiency from the following three aspects: comprehensive energy efficiency by means of DEA, energy consumption per unit of GDP, and the energy efficiency in combination of the former two indexes. After measuring and analyzing the degrees of advancement, rationality and concentration of industrial structure in each city, we generalized the coupling features between energy efficiency and industrial structure in Liaoning by using the coupling degree rating model. Some conclusions can be drawn as follows. (1) The 14 cities differ significantly in their energy efficiency, among which, four cities (Shenyang, Dalian, Anshan and Jinzhou) enjoy the highest energy efficiency, but the northwestern part and other heavy industry cities such as Fushun and Benxi belong to low efficiency and high consumption area. (2) In areas with higher efficiency, the spatial patterns of the comprehensive energy efficiency, the energy consumption for GDP per unit, and the energy utilization efficiency present patterns of ‘π’, ‘II’, and ‘H’, respectively. Geographically, from east to west and from north to south, the energy utilization efficiency shows different trend; the binuclear structure of economic development and other factors have a major effect on the formation of this kind of spatial pattern of energy efficiency. (3) The southeastern part of Liaoning enjoys higher degree of advancement of industrial structure. With Shenyang and Dalian holding two ends, the areas with higher degree of rationality of industrial structure presents an‘H’-shaped pattern. The urban agglomerations in the central and southern Liaoning enjoy higher degree of concentration of industrial structure. (4) The overall coupling degree between energy efficiency and industrial structure is low in the province, but at both ends of Shenyang and Dalian, the coupling degree between the advancement of industrial structure and energy efficiency is relatively high than that of other cities.
