摘　　要：长江经济带发展作为国家重大战略之一,对于推动区域经济协调发展和高质量发展具有重要意义。运用扩展的多区域投入产出模型,编制了长江经济带三大城市群不同年份的区域间投入产出表,比较分析了三大城市群产业关联的特征。研究结果表明:总体来看,长江经济带三大城市群产业发展东强西弱的格局依然存在;从产业贡献度来看,制造业对三大城市群的后向产业关联处于主导地位,而服务业对前向产业关联处于主导地位,区域间产业存在溢出错位现象;从联系紧密程度来看,长江经济带三大城市群区域内产业呈现出集聚性发展特征,区域间产业呈现出联动性和收敛性发展特征。因此,要根据长江经济带三大城市群产业关联特征的动态变化,有针对性地打通堵点、补齐短板,进一步提升长江经济带区域间产业联动发展水平。As one of the major national strategies,the development of the Yangtze River Economic Belt is of great significance for promoting the coordinated development and high-quality development of the regional economy.Using the extended multi-regional input-output model,the inter-regional input-output table of the three major city clusters in the Yangtze River Economic Belt in different years was compiled,and the characteristics of the industrial correlations of the three major city clusters were compared and analyzed.The research results show that:overall,the industrial development pattern of being strong in the east and weak in the west in the three city clusters in the Yangtze River Economic Belt still exists;from the perspective of industrial contribution,the manufacturing industry is in a dominant position in the backward industrial linkage of the three major city clusters,while the service industry is in a dominant position in the forward industrial linkage,and there is a phenomenon of spillover and dislocation between regional industries;from the perspective of the degree of closeness of linkage,the industries within the three major city clusters in the Yangtze River Economic Belt show the characteristics of agglomerative development,and the inter-regional industries show the characteristics of linkage and convergence development.Therefore,it is necessary to open up the blocking points and make up for the shortcomings in a targeted manner,and further improve the level of industrial linkage development among the Yangtze River Economic Belt regions according to the dynamic changes of the industrial correlation characteristics of the three major city clusters in the Yangtze River Economic Belt.
