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。
Based on the method of social network analysis, taking the Wanjiang City Belt as the research object, this paper analyzes the network characteristics of the spatial economic linkages in the urban belt along the Yangtze River in Anhui Province and verifies it with the core-periphery structure model, and concludes that this method is applicable to the urban spatial economic relations In the validity of. The results show that the network structure of spatial economic links in Wanjiang City tends to be complex, but the economic links are still weakly linked. From the point of view of the change trend of centrality, Wuhu has the largest increase in point output, The largest increase; from the center of the comparison we can see that the spatial economic links Wanjiang city is gradually becoming more balanced, but there are obvious structural stratification in the network and verified from the side. At last, the author puts forward the mechanism of driving the change of space economy in the city of Wanjiang along with the accumulation and diffusion of elements, the formation of industrial division of labor system, the innovation of traffic modes and the construction of development zones.
