摘　　要：利用百度地图春节人口迁徙大数据,采取社会网络分析方法,主要从密度、中心性、核心—边缘结构三个方面对长江中游城市群网络特征进行研究。结果表明:(1)长江中游城市群整体网络密度较低,仅为0.4315,城市间联系度不高;(2)长沙、武汉、南昌三个城市中心性相对较高,具有较强的控制力和影响力;(3)长江中游城市群具有较明显的核心—边缘趋势,呈现"金字塔"结构。长沙、南昌对周边城市有较强的带动作用,武汉强"核心"城市的阴影效应明显;(4)城市核心度与城市中心职能强度具有明显的正相关关系。The Middle Yangtze River Valley has become more significant in China＇s regional development pattern due to the reply of the Development Planning of Urban Agglomerations in the Middle Reaches of the Yangtze River. So,studying its network structure and discussing the orderly development mechanism is becoming a focal point in the society.Based on Baidu migration data,this paper studies the network characteristics of the urban agglomerations in the middle reaches of the Yangtze River and by the social network analysis method. The results shows：（1） The whole network density of the urban agglomerations in the middle reaches of the Yangtze River is only 0.4315. Connections between the cities is not high.（2）The centrality of Changsha, Wuhan, Nanchang is relatively high, which means more power and influence.（3） The urban agglomerations in the middle reaches of the Yangtze River has the obvious trend of the core and edge, which shows the ＂Pyramid＂ structure. The driving roll of Changsha and Nanchang to the surrounding cities is remarkable, while Wuhan is not.（4） The urban core degree based on the stream of people has a positive correlation with the strength of the city center.
