Abstract:
ABSTRACT OBJECTIVE：To analyze spatial distribution characteristics of pharmaceutical industry in the Yangtze RiverEconomic Belt，and to provide reference for regional pharmaceutical industry planning. METHODS：Based on the central analysis，agglomerated sub group analysis and secondary assignment program analysis of social network analysis，the industrial relevancebetween regional pharmaceutical industry and regional cities were studied（using the image matrix of agglomerated sub group），using regional pharmaceutical enterprises in the Yangtze River Economic Belt as the research object. RESULTS &CONCLUSIONS：The study involved 111 listed pharmaceutical companies in 82 regional cities，and 82 urban nodes formed aregional pharmaceutical industry distribution network，which could generate 8 urban cohesion subgroups，represented by Shanghai，Chengdu and Chongqing；Shanghai and Hangzhou in the Yangtze River Delta，Chengdu and Chongqing in the Chengdu and Chongqing economic circle have more advanced position in network centrality. The centrality of Shanghai was the highest（25.926），followed by Chongqing and Chengdu（both were 19.753）. It shows that the spatial distribution of the pharmaceuticalindustry in the Yangtze River Economic Belt shows a distribution pattern dominated by the Yangtze River Delta urbanagglomeration. At the same time，the Chengdu-Chongqing urban agglomeration also shows a greater influence. The regional citiesplay different roles in industrial development. Chongqing and Taizhou have shown stronger industrial radiation capabilities，while?Shanghai and Hangzhou have shown stronger industrial absorption capacity.
