长江经济带绿色技术效率与产业结构耦合协调分析

通过对长江经济带2000-2015年绿色技术效率、产业结构高级化、合理化指数进行测算，并分别对绿色技术效率与产业结构高级化、合理化的耦合协调度进行测度，采用层次聚类和变异系数方法对测度结果进一步剖析。结果显示：长江经济带大部分省市绿色技术效率与产业结构高级化的耦合协调结果并不尽如人意，但是省际差距在不断缩小；绿色技术效率与产业结构合理化的耦合协调结果明显较好，但是省际差距在不断扩大；从区域分布的角度来看，长三角地区的耦合协调水平最高，其次为长江中游地区，最低的为经济发展水平相对落后的长江上游地区。

The coupling Coordination Analysis of Green Technology Efficiency and Industrial Structure of Yangtze River Economic Belt

Calculating the green technology efficiency, indexes of advanced industrial structure and rational industrial structure of Yangtze River Economic Belt from 2000 to 2014, this paper measures the coupling coordination degree between green technology efficiency and indexes of advanced industrial structure and rational industrial structure respectively and conducts further study by adopting hierarchical clustering method and variation coefficient method. The results suggest that the gap between provinces has expanded in rational industrial structure while narrowed in advanced industrial structure; the coupling coordination degree between green technology efficiency and indexes of advanced industrial structure is not satisfying yet the gap between provinces has been narrowing. The coupling coordination degree between green technology efficiency and indexes of rational industrial structure is satisfying but the gap has been expanding. From the perspective of regional distribution, Yangtze River Delta is with the highest level, the middle reaches of the Yangtze River rank secondly and the upper reaches of the Yangtze River are with the lowest level.
