【摘要】：利用2014年A股上市公司总部-子公司组织网络数据,采用GIS、Ucinet等网络分析工具,构建了中国286个地级市以上城市网络,并进行综合测度,揭示了企业组织视角下城市网络空间结构的复杂性特征。研究表明:中国上市公司总部的区位分布呈现出较为明显的空间集聚趋势,主要分布在东部沿海的长三角、珠三角、京津冀和山东半岛城市群以及中部的长江中游城市群和西部的成渝经济区等六大城市群内;基于城市网络节点的总联系量对节点进行分级,北京、上海和深圳是全国性的网络中心;城市网络联系量呈现出较为明显的东密西疏、东强西弱的空间梯度格局,其中在高值联系流上又凸显出一个三棱锥体的"钻石"结构,京津、上海、深广和成渝分别为其4个顶点;不同等级的网络联系具有不同的空间异质性,网络的空间组织以核心节点的中心辐射连接与局部地区的近邻交互连接为主;整个网络符合无标度网络特性,并呈现"小世界"网络特征。
[Abstract]:Using the network data of the headquarters of the A shares of A shares in 2014 and the network analysis tools of GIS and Ucinet, the network of cities above the city level in China is constructed and measured. The complex characteristics of the urban network space structure in the perspective of enterprise organization are revealed. The research shows that the regional distribution of the headquarters of the listed companies in China is located. There are more obvious trends of spatial agglomeration, mainly in the Yangtze River Delta, the Pearl River Delta, Beijing Tianjin Hebei and Shandong peninsula urban agglomeration, the middle reaches of the middle reaches of the Yangtze River and the Chengdu Chongqing Economic Zone in the middle of the six major urban agglomeration, and the total links based on Urban network nodes are classified in Beijing, Shanghai and Shenzhen. The network center of the national network shows a more obvious East Mississippi and the East strong west weak spatial gradient pattern, in which the "diamond" structure of a three pyramid is highlighted in the high value connection flow, Beijing, Tianjin, Shanghai, Shenzhen and Chengyu are the 4 points respectively, and the network connections of different levels have different spatial heterogeneity. The spatial organization of the network is mainly connected by the central radiation connection of the core nodes and the adjacent adjacent interconnections in the local area; the whole network conforms to the characteristics of the scale-free network and presents the "small world" network features.
