基于引力模型的皖北城市经济联系研究

摘要

通过构建多维度城市发展质量评价指标体系,借助修正后的引力模型和断裂点模型,定量分析皖北6个地级市之间的空间经济联系.结果表明:皖北各城市间的经济联系普遍较弱,区域中心城市地位不显著,影响力不明显;城市间屏蔽效应渐显,城市发展南强北弱的趋势进一步加剧;城市结构初步显示阜阳—亳州、蚌埠—淮南、宿州—淮北组群发展的"三足鼎立"空间格局.建议各级政府主动转变职能,充分发挥协调、引领作用,加快皖北区域中心城市建设,构建区域经济长效增长机制.%By constructing multi-dimensional quality evaluation index system of urban development,with the aid of the revised gravity model and breaking point model,the paper analyzes the characters of the space links be-tween the six cities in north Anhui.The results show that the economic links between cities is generally weak in north Anhui and that the regional central city status isn't remarkable, the influence of which isn't obvious.This research reaches a conclusion that the shielding effect is outstanding in north Anhui,in which there is huge differ-ence between the southern parts and northern parts.The city group structure preliminarily appears a situation of tri-partite confrontation which inlcudes Fuyang-Bozhou,Bengbu-Huainan and Suzhou-Huaibei.At last,this paper de-duces some enlightening guidance and makes some suggestions.
