【摘要】 探讨长三角地区制造业空间重构和区域关联对经济绩效的影响有助于理解关联视角下产业动态对区域经济发展的作用。基于2018年企业注册信息大数据，借助空间分析和社会网络分析方法考察了长三角地区制造业空间重构和区域关联的特征，利用空间计量模型分析了其对经济绩效的影响。研究发现：(1)长三角地区制造业空间重构、区域关联具有显著的地域差异且行业异质性明显，一般制造业仍然是空间重构与区域关联的主体，上海、苏南和浙北是空间重构与区域关联的核心区。(2)制造业的多样化集聚和产业升级会对经济绩效产生显著的正向影响，产业转移与区域关联对经济绩效的影响与产业发展阶段有关。处于产业优势分散阶段的产业，产业转出与提升网络入度有助于经济绩效增长，而处于产业优势集聚阶段的产业，产业转入促进了经济绩效提升。更多还原

【Abstract】 Exploring the impact of spatial reconstruction and regional relatedness characteristics of the manufacturing industry on economic performance in the Yangtze River Delta(YRD) helps to understand the key significance of industrial dynamics on regional economy from the perspective of relatedness. Based on the data of enterprise registration information in 2018, this study employed spatial analysis and social network analysis methods to investigate the spatial reconstruction and regional relatedness of the manufacturing industry in the YRD. Utilizing spatial econometric models, the impact on economic performance was assessed. The main findings were as follows:(1) The spatial reconstruction and regional relatedness of the manufacturing industry in YRD exhibited significant spatial characteristics and pronounced industry heterogeneity. General manufacturing served as the main component of spatial reconstruction and regional relatedness, with Shanghai, southern Jiangsu and northern Zhejiang as the core areas of these processes.(2) The diversified agglomeration and industrial upgrading of manufacturing had a significant positive impact on economic performance. The effect of industrial transfer and regional relatedness on economic performance depended on the stage of industrial development. For industries in the stage of dispersed industrial advantages, the outflow of industries and the increase in network in-degree contributed to economic growth. Conversely, for industries in the stage of concentrated industrial advantages, the inflow of industries was beneficial to economic performance.更多还原
