摘要
基于社会网络分析的方法,以皖江城市带为研究对象,分析了皖江城市带空间经济联系变化的网络特征,并以核心—边缘结构模型进行验证,得出该方法应用到城市空间经济联系中的有效性。结果显示:皖江城市带空间经济联系的网络结构渐趋于复杂,但经济联系还处于弱联结状态;从点度中心度的变化趋势看,芜湖的点出度增幅最大,合肥的点入度增幅最大;由中间中心度比较可知,皖江城市带空间经济联系正逐步趋于均衡,但网络中存在明显的结构分层并从侧面进行了验证。最后提出要素的集聚与扩散、产业分工体系的形成、交通方式的创新及开发区建设等共同形成了驱动皖江城市带空间经济联系不断变化的机理。
This paper based on the society network analysis＇s view,taking City Belt in Wanjiang region as an example,tries to analyze the space economic contacts＇ network characteristic of City Belt in Wanjiang and has carried on the verfication by the Core-periphery model,obtained effectiveness of the method applied to spatial economic contacts.The results show that： City Belt in Wanjiang spatial economic contacts＇ network structure tends to be complicated,but the value not high,showing a weak tie between the space economic contacts.As to the network degree,Wuhu＇s out-degree increased range is the biggest and Hefei＇s in-degree increased range is the maximum;By the betweenness centrality comparison,spatial economic contacts in City Belt in Wanjiang tends to be balanced gradually,but there＇re the obvious structure lamination in contact network and give the verfication from the lateral side.According to network characteristic of space economic contacts of City Belt in Wanjiang,thought that essential factor＇ agglomeration and diffusion,the industrial division of labor system＇s formation,the transportation way＇s innovation and the development zone construction＇s boost and so on which together formed the main mechanism that actuated space economic contacts promoted continuously in city-groups.
