合肥都市圈中心城市经济辐射范围实证分析

An Empirical Analysis on the Economic Sprawl Scope of Hefei Metropolitan Central City

合肥作为长三角世界级城市群副中心,其经济辐射对合肥都市圈乃至长三角城市群发展有重要意义。从经济联系强度出发,基于城市综合实力,运用经济地理学中的威尔逊模型和断裂点模型并在ARCGIS10.2的支持下勾勒合肥2011年、2013年和2015年的经济辐射范围。结果表明:(1)安徽省各城市中,合肥的综合得分最高,综合实力最强,与其作为合肥都市圈中心城市的地位相符;(2)合肥都市圈的圈内城市与合肥的经济联系强度整体要高于圈外城市;(3)受到南京经济辐射、城市合作竞争关系等因素的影响,合肥对芜湖和马鞍山的辐射力较弱并且有减弱趋势。结合实证分析结果,对都市圈的发展提出诸如增强中心城市综合实力、正确处理合作竞争关系等建议。
