Research on the Yangtze River Delta Urban Agglomeration Network Structure Based on Social Network Analysis
研究了长三角16个主要城市的经济联系，用社会网络分析揭示了城市群网络的形态、结构属性和内部特征，发现网络联系紧密但城市间不平衡，枢纽城市有限，初步形成多中心协同发展格局。
Urban agglomeration networking development will be the one of the basic characteristics of regional integration development in the Yangtze River delta.This paper,which based on the empirical of economic contact among the 16 leading cities in the urban agglomeration in the Yangtze River delta,analyzes the elemental form,network structure property and inside microcosmic characteristic of the urban agglomeration network from the social network analysis perspective.The result shows that urban agglomeration network developed a closely relationship with the formation of network,but the imbalance characteristic among cities is obvious,city nodes with the hub capacity still present in very limited amounts and it preliminary forms a polycentric network and synergetic development pattern.It also provides some suggestions for upgrading the network function of urban agglomeration.
