武汉城市圈城市经济关联及优化研究

基于城市间相互作用强度模型和城市流强度模型,以武汉城市圈为研究区域,对武汉城市圈城市相互作用强度,各城市的区位商、外向功能量、城市流强度以及中心性进行分析与验证.结果表明:武汉城市圈内各城市经济关联强度较弱,城市间经济发展不平衡;武汉市中心地位突出,经济发展呈现"一城独大"格局;武汉城市圈外向型服务功能落后,城市间服务功能不协调;武汉城市圈经济集聚与辐射功能总体较弱,区域一体化尚处于初级阶段.建议:分类引导,提升武汉城市圈城市总体实力;完善交通,强化武汉城市圈网络化结构;明确分工,实现武汉城市圈功能互补;协调发展,增强武汉城市圈城市流强度.

Economic Relation and Optimal Study in Wuhan City Circle

The questions of the inter-urban interaction and the location quotient,the outward function,the degree of urban flow and centrality in each city in Wuhan City Circle were discussed and analyzed,based on the models of the inter-urban interaction and the degree of urban flow. The result showed that: there was a weak and uneven economic relation between cities; the economic pattern that Wuhan city held the only strongest status in the circle had been showed,which represented its conspicuous centrality; there was a backward in outward service function and inharmonious service function between cities in the circle; the regional integration was still at an early stage with the weak function of economic agglomeration and radiation. Accordingly,the optimal strategy was proposed that the development of each city should be promoted respectively in order to receive an overall strength; the transportation should be improved in order to intensify the network structure; the function of each city should be identified in order to realize the functional complementation; the harmonious development should be advocated in order to enhance the degree of urban flow.
