摘　　要：企业市场互动网络是城市网络的重要表现形式。基于全国海量工商企业信息数据库,以中国四大城市群——京津冀、长三角、珠三角和成渝为研究对象,利用大数据匹配方法,构建了城市群企业跨城投资有向加权网络,并对投资网络的空间结构与演化特征进行了分析。主要研究结论如下:2010—2019年,四大城市群投资网络规模与密度均呈现一定的增长趋势。在空间格局方面,京津冀城市群呈现以石家庄—北京—天津为中心的倒“V”型结构,长三角城市群呈现以上海为核心的多轴式发展,珠三角城市群呈菱形结构稳定发展,成渝城市群呈现出成都—重庆双核联动、成都单核辐射的空间格局。从城市层级来看,四大城市群投资网络的“核心—边缘”结构特征明显,但城市节点层级存在显著的异质性。In recent years,urban network relationships based on factor linkages have received widespread attention from economic geographers.Based on the information database of industrial and commercial enterprises,this paper constructs a directional weighted network of investment in four major urban agglomerations in China-Beijing-Tianjin-Hebei,Yangtze River Delta,Pearl River Delta and Chengdu-Chongqing i and describes the spatial structure and evolutionary characteristics The main conclusions of the study are as follows:During the evolution process from 2010 to 2019,the scale and density of the investment networks of the four major urban agglomerations show a certain growth trend.From the perspective of spatial pattern,Beijing-Tianjin-Hebei shows a Shijiazhuang-Beijing-Tianjin From the perspective of spatial pattern,Beijing-Tianjin-Hebei shows the inverted"y"-shaped structure of Shijiazhuang-Beijing-Tianjin,the Yangtze River Delta city cluster shows a multi-axis development with Shanghai as the core,the rhombus structure of Guangzhou-Shenzhen-Zhuhai-Foshan in the Pearl River Delta city cluster has been stabilized,and the Chengdu-Chongqing city cluster shows the spatial pattern of Chengdu and Chongqing with a double core and Chengdu with a single core.In terms of city level,the investment network pattern of the four major city clusters has a clear"core-edge"structure,but there is significant heterogeneity in the level differences of city nodes.
