中原经济区城市内在经济联系分析

基于城市流强度模型和城市间相互作用强度模型,以中原经济区29个城市为研究区域,对中原经济区的城市内在经济联系进行了分析。结果表明：①中原经济区整体的集聚和辐射能力较弱,经济发展尚处在初期阶段,郑州、洛阳的核心带动作用不够突出;②经济区城市内部产业部门分配上差距较大,城市内部产业间,城市间经济发展不平衡;③中低级城市数量较多,具有较大的发展潜力;④中原经济区内城市总体经济实力和城市综合服务能力之间尚不协调;⑤中原经济区内城市间经济联系不够紧密,以郑州为中心,呈中心外围的空间结构,省际城市之间联系贫乏。据此,提出了优化中原经济区城市经济联系的对策,服务于中原经济区的发展。

Analysis of the Inherent Functional Relations of Central Plains Economic Region

Based on the model of the intensity of urban flow and the contact intensity among cities,29 cities in Central Plains Economic Region as the study area,analyzed the economic relations of cities in Central Plains Economic Region.The results showed:①The total concentration and radiation in Central Plains Economic Region is weak,the economic development is still at the initial level and the core role in driving of Zhengzhou and Luoyang is not outstanding enough.②The difference is big on the distribution among departments of the city and the economy is imbalanced in cities and internal departments in the Central Plains Economic Region.③The quantity of potential small-medium cities is large.④It is not coordinated between urban economy and comprehensive service of cities in Central Plains Economic Region.Urban economy and comprehensive service of cities are not coordinated.⑤Central Plains Economic Region has a Core-space structure with Zhengzhou as a center.The economic links among cities in Central Plains Economic Region is not quite close and the contact among cities of provinces is poor.Accordingly,countermeasures are put forward to increase economic link among cities in Central Plains Economic Region so that they can serve the development of economic region.
