基于生产性服务业的中国省会城市网络结构研究

China′s Provincial Capital Network Based on Producer Service Industries

基于银行、证券、保险、会计、物流和广告六大类、472家国内领先的生产性服务企业在中国31个省会城市跨区域经营形成的企业组织关系数据,运用互锁网络模型,对中国省会城市网络的整体结构、功能结构和“城市对”结构进行实证分析。在整体网络结构方面,中国省会城市网络的主要服务联系已形成以京、沪、广、蓉4个城市为顶点的 “金字塔”形结构;中国省会城市网络的空间连接方式呈现出跳跃式和邻近式交织并存的特征,但省会城市网络的空间连接存在明显的断层区。在功能网络结构方面,中国省会城市网络的主体结构呈现单中心与多中心并存的态势,且具有明显的高行政级别城市空间指向性和板块分异性。在“城市对”结构方面,中国省会城市网络的“城市对”分布呈现出显著的京、沪指向性,并且四大板块及胡焕庸线两侧的“城市对”分布具有明显的区域差异性。

This research makes an empirical analysis of China′s provincial capital network,specifically its overall structure,functional structure and "city-dyad" structure.The analysis has been made by use of interlocking network model based on the location strategies of 472 leading domestic producer service firms in 31 provincial capitals across banking,security,insurance,accounting,logistics and advertising sectors.The principal findings are as follows:1) In the aspect of overall network structure,the backbone of China′s provincial capital network is pyramid-shaped,which is anchored by Beijing,Shanghai,Guangzhou and Chengdu.The spatial connecting pattern of China′s provincial capital network features the coexistence of jump linkage and adjacent linkage.However,several obvious connection gaps are found in the spatial connection of the overall network.2) In the aspect of functional structures of China′s provincial capital network,some are unicentric,and the others are polycentric.All the functional networks are inclined to gather to the high administrative level cities and exhibit regional disparities.3) In the aspect of "city-dyad" structure of China′s provincial capital network,Beijing and Shanghai act as the leading linkage partner of every provincial capital in both the overall network and the functional networks.The distributions of city-dyads in the Four Regions and two sides of Hu Line show significant regional heterogeneity.
