跨区域城市群经济网络的动态演化——基于海西、长三角、珠三角城市群分析

在改进的引力模型基础上,采用社会网络分析方法和探索性空间数据分析方法,对2004-2015年海峡西岸城市群与长三角、珠三角城市群经济网络的动态演化进行分析.结果 表明:海峡西岸城市群与长三角、珠三角各个城市的联系不断加强,但海峡西岸城市群大部分城市在经济网络中的重要性偏弱;跨区域城市群中缺乏城市规模辐射及城市功能互补两方面均较突出的城市,但核心城市基于规模辐射发挥明显的空间集聚效应;增强城市功能互补是加强跨区域城市群经济网络联系程度的关键所在.

Dynamic Evolution of Economic Network within Inter-Regional Urban Agglomerations:Based on the Urban Agglomerations of West Coast of Taiwan Straits,Yangtze River Delta and Pearl River Delta

On the basis of the improved gravitational model, this paper used social network analysis and exploratory spatial analysis to analyze the dynamic evolution of economic network within inter-regional urban agglomerations among the urban agglomerations of West Coast of Taiwan Straits, Yangtze River Delta and Pearl River Delta during 2004 and2015. The conclusions are as follows: The strength of connections between the urban agglomeration of West Coast of Taiwan Straits and Yangtze River Delta or Pearl River Delta urban agglomeration has been growing, but most of the cities in the West Coast of Taiwan Straits urban agglomeration play less vital role in the economic network. The economic network lacks cities which show prominent value in both urban scale radiation and complementarity of urban function.However, the core cities in the inter-regional urban agglomerations create obvious spatial agglomeration effect based on scale radiation. Strengthening the complementarity of urban function is the key to reinforce the economic connection level of inter-regional urban agglomerations.
