【摘要】 “双循环”背景下，以城市群、都市圈为主的城市区域已成为我国参与全球竞合的主要空间单元。基于工商企业注册数据、省级及以上开发区数据、工业用地数据，采用核密度分析、热点分析等方法，识别长三角产业空间的历时态演化及现时态格局特征；在此基础上，构建“行为主体—环境要素—空间效应”的产业空间格局形成机理解析框架，提出长三角产业空间格局的优化策略。研究表明，行为主体促进长三角外围浙南沿轴带集聚与苏北皖北均衡式扩散，环境要素支撑长三角核心区“Z”字形产业廊道及产业集群发展，行为主体与环境要素的耦合作用，推动形成长三角产业空间核心区“Z”字形集聚+外围南北分异，是城市区域产业空间格局形成的关键机制；长三角产业空间格局优化应注重多尺度生产空间的集聚组织，推动由“核心—边缘”模式向区域均衡模式转变。更多还原

【Abstract】 Under the background of"dual circulation",urban areas dominated by city clusters and metropolitan areas have become the main spatial units for China to participate in global competition.Based on the registration data of industrial and commercial enterprises,provincial and above development zone data,and industrial land data,using methods such as kernel density analysis and hotspot analysis,identify the temporal evolution and current pattern characteristics of the industrial space in the Yangtze River Delta;On this basis,an analytical framework for the formation mechanism of the industrial spatial pattern of"behavioral subjects environmental factors spatial effects"is constructed,and strategies for optimizing the industrial spatial pattern in the Yangtze River Delta are proposed.Research has shown that behavioral entities promote agglomeration and balanced diffusion along the axis of northern Jiangsu,northern Anhui,and southern Zhejiang in the periphery of the Yangtze River Delta.Environmental factors support the development of the"Z"-shaped industrial corridor and industrial clusters in the core area of the Yangtze River Delta.The coupling effect between behavioral entities and environmental factors promotes the formation of a"Z"-shaped agglomeration in the core area of the Yangtze River Delta industrial space and the differentiation of the periphery from north to south,which is a key mechanism for the formation of the urban regional industrial spatial pattern;The optimization of the industrial spatial pattern in the Yangtze River Delta should focus on the agglomeration and organization of multi-scale production spaces,and promote the transformation from a"core-periphery"model to a regional equilibrium model.更多还原
