长三角城市群网络化结构特征研究及实证分析

长三角城市群作为中国经济活动最活跃的地区之一,城市群网络化发展的将是长三角城市区域今后发展的主要特征.文章借鉴社会网络分析方法和城市引力模型,以长三角城市群16个中心城市间的经济联系为例,对长三角城市群网络的基本形式、结构属性和网络微观特征进行实证分析.研究发现长三角城市群经济关联具备了网络化规模,但内部各城市间联系不均衡性特征明显,多中心网络协同发展格局已初步形成；通过网络分析进一步提出为实现长三角城市群网络化发展的政策建议.

An Empirical Research on the Characteristics of Yangtze River Delta Urban Agglomeration Network Structure

The Yangtze River Delta urban agglomeration is one of China’s most active economic development regions,urban agglomeration networking development will be the main characteristics of the urban regional development in the future.Based on the network of economic contact among the 16 central cities of the urban agglomeration in the Yangtze River delta,this paper draw on the social network analysis and city gravity model,made an empirical analysis on elemental form,structure property and microcosmic characteristic of Yangtze River delta urban agglomeration network.The results show that urban agglomeration economic contact network was able to fulfill medium scale,but the imbalance characteristic of cities interior contact was obvious,and it’s preliminary forming a polycentric network and synergetic development pattern.
