Taking the panel data of 11 provinces and municipalities in Yangtze River Economic Zone from2007 to 2016 as research object,this paper conducts comparative analysis of coupling interaction by dividing Yangtze River Economic Zone into 3 parts such as Upper Yangtze River Basin,Middle Yangtze River Basin and Yangtze River Delta Area,constructs indicator system for new-type urbanization and greening of industry,uses entropy power method to calculate index weights,and makes empirical analysis for the development of new-type urbanization and greening of industry and the coupling interaction between the two.The research results show that on the temporal level,the new-type urbanization develops at a fast speed while the greening of industry develops at a slow speed as a whole.The greening of industry is even reduced in Upper Yangtze River Basin and Middle Yangtze River Basin,which leads to the huge difference of the coupling coordination of the two systems among the regions.On the spatial level,there is an obvious gap among the regions and between the cities within the regions on the development of new-type urbanization,greening of industry and the coupling coordination.Meanwhile,the gap has been enlarging between the backward provinces and municipalities and the leading provinces and municipalities annually.
