长江三角洲城市群工业生态效率评价

摘要

The Yangtze River Delta is one of the important regions with economic development.Based on the industrial data of 35 cities from 2010 to 2013 and by decomposing industrial ecosystem into industrial economy, environment, energy three subsystems, the paper evaluates the efficiency of 35 urban industrial ecosystems and three subsystems by use of network DEA model.The results show that, in the case of industrial economic subsystems, the industrial economy is highly efficient area forming "M",which is centered on Shanghai and other cities;in terms of environmental subsystems, the cities with high environment efficiency are centered on Taihu, along the Yangtze River and Hangzhou Bay area;in terms of energy subsystems, Shanghai, Suzhou and other cities have high energy efficiency, energy efficiency of other cities is low and the difference of efficiency level is small;in terms of industrial ecosystem, industrial eco-efficiency of urban agglomeration in the Yangtze River Delta shows three steps.%长江三角洲是我国经济发展的重要地区之一,基于长江三角洲35个城市2010-2013年的工业数据,通过将工业生态系统分解为工业经济、环境、能源三个子系统,采用网络DEA模型对长江三角洲城市群的35个城市工业生态系统及三个子系统效率进行评价.研究结果显示:就工业经济子系统而言,工业经济高效率城市出现密集,形成了以上海等城市为中心的"M"形分布;就环境子系统而言,环境高效率城市主要分布在以太湖为中心、长江沿岸及杭州湾沿线的地区;就能源子系统而言,以上海、苏州等城市能源效率较高,其它城市能源效率较低且效率水平差异较小;就工业生态系统而言,长江三角洲城市群工业生态效率呈现三阶梯状.
