南京都市圈制造业与生产性服务业空间分布 及其协同集聚研究

ANALYSIS ON THE SPATIAL DISTRIBUTION AND COLLABORATIVE AGGLOMERATION OF MANUFACTURING AND PRODUCTIVE SERVICES IN NANJING METROPOLITAN AREA

基于企业大数据资源,结合空间外部经济理论和“中心—外围”理论,对南京都市圈内两大产业的空间分布及协同集聚水平进行深入分析。研究发现:(1)南京都市圈内制造业与生产性服务业形成了“一极、两区、多组团+多点”的独特格局,且生产性服务业集聚强度高于制造业;(2)制造业呈现以南京市为中心向周边县市区扩散的趋势,而生产性服务业则倾向于向各城市的核心城区聚集发展。(3)南京都市圈内中心城区的协同集聚水平低于边缘县区地带。

The paper based on enterprise big data resources,combined with spatial external economic theory and“center-periphery”theory,analyzed the spatial distribution and collaborative agglomeration level of of the two major industries within the Nanjing metropolitan area.The study finds that:(1)The manufacturing and productive service industries follow the spatial distribution characteristics of“one pole,two districts,multiple clusters+multiple points”.The concentration level of the productive service industry is higher than that of the manufacturing industry.(2)The manufacturing industry is expanding outward,with Nanjing as the center,while the productive service industry is gathering in various cities urban centers.(3)The level of collaborative agglomeration in the central urban area of the Nanjing metropolitan area is lower than that in the peripheral county areas.
