摘要
企业作为市场敏感度更高的经济主体,推动着要素资源在城市群地区流动,形成了独特的城市群企业网络。文章以上市公司总部与分支机构的跨区域关联作为城市群流空间网络的表达参数,利用空间可视化、R语言、社会网络分析等手段,对2005—2020年成渝城市群网络空间结构时空演变格局进行刻画,结果发现:(1)与重庆和成都的两个核心城市空间邻近性长期主导着成渝城市群企业流空间格局及其演变,但有效次核心城市仅出现在成都周边的德阳市,城际企业流的多向交叉关联驱动成渝地区中部“塌陷”现象逐步缓解,北部、南部的边缘化“窘境”有所改善;(2)2010年后,位于非中心城市的上市公司其分支机构倾向从重庆转向成都,致使成都的结构性网络权力强度“超车”重庆,且不断压缩重庆的经济腹地;(3)虽然各城市的企业中心性位次有所变动,但成都、重庆两个核心城市对其他城市派生出的企业分支机构的获取及控制权力始终具有优势,成都企业的跨区域分布更为活跃;(4)企业为追求利润最大化,会根据资本逐利需要不断重构其企业流网络,驱动成渝城市群空间结构由“单核主导”向“双核鼎立”、再向“多核均衡”演化,同时核心层与次核心层节点城市数量增多,边缘层节点城市数量减少,符合空间自组织规律。
As an economic entity with higher market sensitivity,enterprises promote the flow of factor resources among urban agglomerations,which forms the unique network structure of urban agglomeration enterprise. This article attempts to use the cross-regional association between the headquarters and branches of public companies to construct the space flows of urban agglomeration. Through spatial visualization, R language, social network analysis, it describes the spatial and temporal evolution pattern of the network spatial structure of Chengdu-Chongqing urban agglomeration from 2005 to2020. The results indicate that: 1) The spatial contiguity of Chongqing and Chengdu has long dominated the spatial pattern and evolution of enterprise flow in Chengdu-Chongqing urban agglomeration,but the effective sub-core cities only appear around Chengdu. The multi-directional cross-driving of intercity enterprise flow has gradually alleviated the lowlevel flows in the center of Chengdu-Chongqing urban agglomeration. And the marginalization dilemma in the north and south has improved. 2) The branches of public companies in non-central cities are transferred from Chongqing to Chengdu after 2010, resulting the structural network power of Chengdu exceeding Chongqing and continuously compressing Chongqing 's economy. 3) Although the enterprise centrality of each city has changed, Chengdu and Chongqing have always had advantages in obtaining and controlling the power of enterprise branches derived from other cities. The cross-regional distribution of enterprises in Chengdu is more active. 4) In order to maximize profits,enterprises will constantly reconstruct their enterprise flow network, which will drive the spatial structure of Chengdu-Chongqing urban agglomeration to evolve from the "single-core" pattern to the "dual-core" pattern and then to the "multi-core" pattern. At the same time,the number of node cities in the core layer and the sub-core layer increases,and the number of node cities in the edge layer decreases,which conforms to the rule of spatial self-organization.
