中国城市群产业生态化及其空间特征

Industrial of Ecologicalization in China’s Urban Agglomeration and Its Spatial Characteristics

文章将生态效率作为一项重要指标评定产业生态化程度,采用主成分分析法对2003-2016年中国城市群195个城市的相关指标进行科学处理,在超效率DEA模型基础上,进一步对中国城市群产业生态效率进行评价,最后探究中国城市群产业生态化空间差异。结果表明:2003-2016年各城市群产业生态化发展稳定,个别年份小幅度变化,产业生态化总体水平有所上升,但仍存在进步空间;从各地级市产业效率的发展情况看,经济实力越强的城市产业生态化效率越高,北京、上海的产业生态化综合得分最高,平均得分均超过1;从时空特征来看,我国各城市群产业生态化地带性差异显著,呈现出从东部沿海向西部地区递减的趋势。

This paper takes eco-efficiency as an important indicator to assess the degree of industrial ecologicalization.Firstly,the paper uses the principal component analysis method to scientifically process the relevant indicators of 195 cities in China’s urban agglomeration from 2003 to 2016.Secondly,on the basis of the super-efficiency DEA model,the paper further evaluates the industrial eco-efficiency of China’s urban agglomeration.And finally the spatial differences of industrial ecologicalization in China’s urban agglomeration is explored.The results show that from 2003 to 2016,the eco-industrial development of all urban agglomerations is stable,with a small change in individual years,and the overall level of eco-industrial development has increased,but there is still room for progress;from the perspective of the development of industrial efficiency in various prefecture-level cities,the higher the eco-efficiency of industrial development in cities with stronger economic strength,the higher the comprehensive score of industrial eco-development,and Beijing and Shanghai have the highest comprehensive score of industrial ecology,with an average score over 1;from the perspective of time and space characteristics,the zonal differences of industrial ecologicalization in China’s urban agglomerations are significant,presenting a trend of gradual declining from the east coastal areas to the western regions.
