Abstract: 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.

Key words: green technology efficiency, advanced industrial structure, rational industrial structure, coupling coordination, yangtze river economic belt
