摘　　要：“流”空间视角是互联网时代人文地理学研究新的视角之一.基于百度指数构建2013年和2018年的辽中南城市群的城市网络联系矩阵,运用复杂网络分析方法,从网络密度、网络中心性、凝聚子群3方面对辽中南城市群网络结构特征进行分析,并对其发展模式选择进行相关探讨.结果表明:①辽中南城市群网络密度整体虽有较大提升,但仍处于较弱的联系状态,未来需继续深化城市间的联系强度;②城市群内各城市的中心度呈现两极分化的现象.沈阳、大连作为辽中南城市群的核心城市,其极化效应开始向扩散效应转变.沈阳媒介作用稳固,大连的网络核心地位逐步建立.③辽中南城市群的三片区格局逐渐形成,沈阳-大连轴线子群成为区域联系的核心子群,城市群内子群间的差距进一步加大;④“一轴双核”的发展模式已经形成,未来应突出“以线带面”的发展模式,重点培育鞍山和丹东作为新的“中间人”的角色,带动其他片区的发展,以实现辽中南城市群可持续性的网络化发展.In the Internet era,the“space of flow”has become a popular topic in the study of human geography.This paper builds a city network connection matrix based on the average Baidu search index between 10 cities in the mid-southern Liaoning urban agglomerations in 2013 and 2018.Applying a social network analysis methodology,the network structure characteristics of urban agglomeration as seen in mid-southern Liaoning are analyzed from the aspects of network density,network centrality,and cohesive subgroups.We also discuss what development model should be chosen in this region.The main conclusions are as follows.①Despite the improvement in connection network density of mid-southern Liaoning urban agglomeration,the connections remain weak.In the future,greater efforts should be made to increase the intensity of connections between cities.②The centrality of cities is polarized.Shenyang and Dalian are the core cities in the urban agglomeration,and their polarization effect has been shifting toward a diffusion effect.In terms of the two cores,Shenyang has always played a media role,and Dalian’s network core position has gradually been established.③The pattern of the three sub-structures of the urban agglomeration formed gradually,and the Shenyang-Dalian subgroup became the core subgroup.Over time,the gap between sub-groups within the urban agglomeration has widened.④At present,the development model of urban agglomeration has the characteristics of“one axis and two cores”.In the future,we should take“line-to-surface”as the main development model,and focus on cultivating the role of Anshan and Dandong as new“intermediaries”to promote development in other areas,and ultimately realize the integration development of the network in the mid-southern Liaoning urban agglomerations.
