| 摘 要： | 基于2005、2010及2015年东北地区城市间铁路客运班次数据,从网络密度、节点层级、网络层级等3个视角对东北地区城市网络演变进行分析,借助社会经济因子、信息网络进行相关性探讨。结果表明：① 区域网络密度得到明显提升但网络空间拓展相对缓慢、城市联系在地域空间内呈“核心-边缘”格局,网络类型由普列主导逐步向高铁主导转变。② 度数中心度视角下的城市等级体系处于稳定状态、区域核心及次级核心集中分布在哈大沿线;而中介中心度视角下的城市等级体系变动较大、核心城市控制力弱化明显、高位序城市出现空间“跃迁”现象;城市中心度基本反映城市在区域发展中的角色与地位。③ 铁路客运视角下的多层级网络演变分别透视出区域核心组织结构拓展、省域关联格局的孕育与发展、区域网络完善程度;客运与信息核心联系网络均凸显了哈大轴线的主导地位,但二者在城市联系尺度上具有差异性：客运网络的跨区域性特征显著、而信息网络则倾向省域尺度。

| Abstract: | Traffic flow is a significant content to represent the social and economical ties of intercity, and is widely used in urban network research in large data age. This article analyzes the evolution of urban network in Northeast China from the three perspectives of network density, node role and network level based on OD data of railway passenger trips between cities in Northeast China in 2005, 2010 and 2015. And with the help of socio-economic factors, information network to explore the relevance. The results show that: 1) Regional network density has been significantly improved, spatial linkage is “core-periphery” pattern, the network level gradually led by the Pulai network gradually to the high-speed rail network-led change. 2) From the perspective of degree centrality, the regional cities has experienced the rising and developing process of unbalance-relative equilibrium-unbalance. The regional urban hierarchy system is in steady state, Shenyang has a strong monopoly position, Harbin, Changchun, Dalian and other regional major cities have a rapid promotion in external contact level. High level cities are concentrated along the Harbin-Dalian. However, in the view of the betweenness centrality, the urban hierarchy system changes greatly, regional urban network control tends to be balanced, the effect of passenger network on the path dependence of the core city is obviously reduced; and the high order cities appear the phenomenon of spatial “transition”. Degree centrality is a relatively comprehensive depiction of the role and position of the city in the development of the region, while betweenness centrality has a certain characterization on urban population scale. 3) The evolution of the multi-level network from the perspective of railway passenger transport is the expanding of regional core organizational structure, the birth and development of provincial association pattern, the degree of regional network perfection. The spatial and temporal compression effect of different “flow” factors affects the urban role and regional network structure in the network. Passenger and information core network have highlighted the strong resources gathering capability of Shenyang-Changchun-Harbin-Dalian 4 core cities and Harbin-Dalian spindle. The core passenger network has a certain cross regional nature, and the inter provincial cities have strong connections. The new element network represented by information is “hub-and-spoke” spatial organization form in space. Urban nodes are closely linked in the provincial space and have obvious “core edge” features. The cross-regional characteristics of passenger networks are significant, while the information network tends to be provincial scale. |
