摘要/Abstract

摘要： 区域产业结构调整是能源效率提升的重要途径。利用能源效率指数、高级度指数和耦合度模型，评价2006—2016年江苏省地级市制造业能源效率和结构高级度，测算能源效率与结构高级度的耦合度并划分耦合类型，分析不同耦合类型区的制造业结构特征。研究表明：1)研究区能源效率整体上呈现“东高西低、南北分化”的空间特征，高能效地区主要分布在南通、盐城和宿迁，低能效地区分布在淮安、连云港和徐州；2)制造业结构高级度以南京—苏州为高值区的两极格局显著，南部地区整体高于北部地区；3)制造业能源效率与产业结构高级度整体处于初级耦合协调水平，南通、盐城为高度耦合地区；4)根据各城市制造业能源效率与结构高级度耦合关系，划分3种耦合类型区，发现低能源效率-低制造业高级度区域的低附加值、高能耗制造业部门占比较大，是产业结构优化、提高能源效率的关键区域。

Abstract: The adjustment of regional industrial structure is an important way to improve energy efficiency. This paper evaluates the energy efficiency and structure up-grade index of manufacturing industry in prefecture-level cities of Jiangsu Province from 2006 to 2016 by constructing energy efficiency index, using up-grade index and coupling degree model. In addition, it calculates the coupling degree between energy efficiency and structure up-grade index, and divides the coupling types. Moreover, the structural characteristics of manufacturing industry in different coupling areas are analyzed. As a result, it shows that: 1)The energy efficiency is high in the east and low in the west and differentiated between the north and the south as a whole. In addition, the areas with high energy efficiency are mainly distributed in Nantong, Yancheng, and Suqian. At the same time, the areas with low energy efficiency are distributed in Huai’an, Lianyungang, and Xuzhou. 2)The bipolar pattern of manufacturing structure up-grade index in Nanjing-Suzhou is significant, and the overall level of the southern region is higher than that of the northern region. 3)The manufacturing energy efficiency and industrial structure in the study area are at the primary coupling coordination level as a whole, while Nantong and Yancheng are highly coupled areas. 4)Three kinds of coupling areas are divided according to the coupling relationship between energy efficiency and structural advanced degree of manufacturing industry in each city. The result shows that low energy efficiency-low manufacturing advanced degree region has a relatively large proportion of low added value and high energy consumption manufacturing sector, which is the key area to optimize the industrial structure and improve the efficiency of energy resources.
