摘要
基于流空间可以有效刻画特殊地域城市群企业异地投资网络。基于土地利用和工企登记数据,采用股权穿透法获取1950~2020年环鄱阳湖城市群42个县区工商企业异地投资数据,分别从“主要节点-骨干路径-空间格局”层面揭示环鄱阳湖城市群企业异地投资网络的结构及演化特征。研究结果表明:(1)节点加权入度逐渐上升,南昌辐射带动作用显著,净流动空间分布不均衡性突出,区位倾向性特征明显;(2)骨干路径主要发生在南昌、九江、鹰潭、抚州以及景德镇等经济发展水平较高的市辖区,跨越地理要素阻碍现象明显;(3)行业整体上朝多中心结构发展,批发和零售业企业异地投资网络结构由单中心向多中心演变,金融业向多地平级互通格局演变,租赁和商务服务业演变为三中心,制造业呈现南移东进的趋势。
Space of flow can be used to effectively depict the remote investment network of enterprises in special regional urban agglomeration.Based on the registration data of industrial and commercial enterprises and land use data,this paper adopts the equity penetration method to obtain the remote investment data of industrial and commercial enterprises in 42 counties and districts from 1950 to 2020 and reveals the structure and evolution characteristics of the remote investment network of enterprises around Poyang Lake urban agglomeration from the level of“main node-backbone path-spatial pattern”respectively.The research results show that:(1)The weighted in-degree of nodes gradually increases,the radiation driving effect of Nanchang is significant,the problem of unbalanced net flow spatial distribution is prominent,and the characteristics of location tendency are obvious.(2)The backbone path mainly occurs in Nanchang,Jiujiang,Yingtan,Fuzhou,Jingdezhen,and other municipal districts with good economic development,which crosses the obstacles of geographical elements.(3)The industry as a whole is developing towards a multi-center structure,and the remote investment network structure of wholesale and retail enterprises has evolved from a single center to a multi-center,the trend of the financial industry is to evolve to multiple places,flat level,and the interworking pattern,the leasing and business service industries have evolved into triple centers,and the manufacturing industry shows a trend of moving south and east.
