摘 要 目的：分析我国长江经济带医药产业的空间分布特征，为区域医药产业规划提供参考。方法：应用社会网络分析法中的中心性分析、凝聚子群分析和二次指派程序分析，以长江经济带区域医药企业为研究对象，对区域医药产业与区域城市的产业关联性（采用凝聚子群的映像矩阵）进行研究。结果与结论：研究共涉及82个区域城市的111家上市医药企业，82个城市节点形成区域医药产业分布网络，可以生成8个以上海、成都和重庆为代表的城市凝聚子群，长江三角洲地区的上海、杭州，成渝经济圈的成都和重庆在网络中心性指标均处于领先位置，如在中心性分析中，上海的度数中心度最高（25.926）、其次是重庆和成都（均为19.753）。显示长江经济带医药产业的空间分布呈现出以长江三角洲城市群为主的分布格局，同时成渝城市群也表现出较大的影响力，区域城市在产业发展中起到了不同的作用，重庆与台州表现出更强的产业辐射能力，而上海与杭州则表现出更强的产业吸收能力。

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.
