长江经济带制造业高质量发展空间关联结构及其效应研究

Study on the spatial correlation structure and its effects of high-quality development of manufacturing industry in the Yangtze River Economic Belt

基于新发展理念构建制造业高质量发展综合评价体系,运用熵值—TOPSIS模型测度综合指数,结合修正后引力模型与社会网络分析法,对长江经济带制造业高质量发展空间关联结构及其效应进行实证研究。结果表明:(1)长江经济带制造业高质量发展存在显著的空间分异及非均衡分布特征。(2)空间关联结构由“单节点发展模式”演化为“点轴发展模式”,空间溢出效应和辐射带动效应显著。(3)整体网络特征向网状化、稠密化、纵深化发展;个体网络特征显示,上海、南京、苏州等城市为核心扩散点,网络向均衡化和片区化发展,且形成了“由东向西扩展,由沿海向内陆延伸”的“核心-半边缘-边缘”结构特征。(4)时空距离、社会消费品零售总额、制造业从业人员数差异是影响长江经济带制造业高质量发展空间关联结构特征的重要因素。

Based on the new development philosophy,this paper constructed a comprehensive evaluation system for high-quality development of manufacturing industry,and used the Topsis entropy method to measure the comprehensive index,combined with the modified gravity model and the social network analysis method,to carry out an empirical study on the spatial correlation structure and its driving factors of high-quality development of manufacturing industry in the Yangtze River Economic Belt.The results showed that:①There was significant spatial differentiation and unbalanced distribution in the high-quality development of manufacturing industry in the Yangtze River Economic Belt.②The spatial correlation structure evolved from“single node development mode”to“point-axis development mode”,with significant spatial spillover and radiation-driven effects.③The characteristics of the overall network was developing towards reticulation,densification and depth,while the characteristics of the individual network showed that Shanghai,Nanjing,Suzhou and other cities were the core diffusion points,and the network was developing towards equalization and fragmentation,and forming the structural characteristics of“core-semi marginal-peripheral”which was“expanding from the east to the west,and from the coast to the inland”.④Differences in spatial and temporal distance,total retail sales of consumer goods,and the number of employees in the manufacturing industry were important factors affecting the structural characteristics of spatial correlation of high-quality development of the manufacturing industry in the Yangtze River Economic Belt.
