摘要
基于城市间公路客运及百度指数大数据,借鉴社会网络分析理论和方法,从城市节点、整体网络及组织模式视角,对成渝城市群城市网络进行深入对比研究。结果显示:(1)程度中心度视角下的成渝城市群城市体系具有首位城市垄断性特征,区域城市外向及内向中心度呈两极分化现象。(2)不同流空间视角下的城市联系均处于弱连接状态。交通流视角下的城市网络出现空间集聚现象,而信息流网络则呈现出相对均衡的发展态势;交通、信息网络中的成渝双核具有较强的对外联系水平,进一步凸显出成渝双核在城市群中的主导地位。(3)交通流视角下的城市组团形成相对完整且稳固的四大板块,信息流视角下的城市组团则处于零散状态,而在核心网络组织结构中,交通流相对紊乱并与城市规模、地理区位等社会经济要素间呈现出一定的相关性,信息流则趋于稳定。(4)在综合城市发育、整体网络、城市组团及核心网络基础上,提出流空间视角下的成渝城市群"轴-辐"式空间组织模式。
Based on intercity road passenger transport and the big data of Baidu index,using the theory and method of social network analysis for reference,this paper makes a deep comparative study on the urban network of Chengdu-Chongqing Urban Agglomeration from the urban node,whole network and organizational pattern.The results show that：（1）The urban system of Chengdu-Chongqing Urban Agglomeration under the angle of degree centrality has the characteristics of the first urban monopoly,and the outward and inward centrality of regional cities are both polarized.（2）The urban connection is in the weak connection state from the perspective of different space of flows.The urban network under the traffic flow angel has the phenomenon of spatial agglomeration,while the information flow network shows a relatively balanced development trend.In the network of traffic and information,Chengdu and Chongqing dual cores have a strong level of external contact,which further highlights the dominant position of Chengdu and Chongqing in the urban agglomeration.（3）The urban groups in the perspective of traffic flow form four relatively complete and stable plates,while the urban groups are scattered in the perspective of information flow.In the organizational structure of the core network,the traffic flow is relatively disordered and has a certain correlation with the social and economic factors such as city scale and geographical location,while the information flow tends to be stable.（4）Based on the comprehensive urban development,the whole network,the urban group and the core network,this paper puts forward the spatial organization model of the hub-and-spoke system of ChengduChongqing Urban Agglomeration from the perspective of space of flows.
