首发时间:2009-03-31
摘要:综合运用聚类分析、因子分析和引力模型,对河南省永城市的城市产业发展阶段、城市职能类型、区域中心性和主要经济联系方向进行了分析。主要结论包括:(1)当前永城市的产业发展阶段正处于工业化初期向中期转变的过渡阶段;(2)对全国城市的聚类分析表明,永城市在全国城市职能分工体系中属于“其它三产、行政或交通职能明显的中小型高度专业化矿业城市”;(3)基于因子分析对永城区域中心性的计算表明:永城市的城市中心性在所有豫东地区县(市)中位居第一位,具有打造豫东区域中心城市的潜力和基础;(4)通过引力模型分析表明:城市的主要经济联系方向为淮北和徐州所在的东北方向,与所在地级市商丘市区的经济联系并不紧密。

RESEARCH ON CITY FUNCTION AND REGIONAL CENTRALITY OF YONGCHENG CITY
Abstract:Jointly using cluster analysis, factor analysis and gravity model, this paper analyzes the industrial development phase, city function type, regional centrality and major directions of economic linkages of Yongcheng city. Key findings include; (1) the industry development stage of Yongcheng is amid a transitional period from primary phase to mid-term phase; (2) the result of cluster analysis shows that the city function type of Yongcheng belongs to “small and meddle size mine cities” in China’s urban system; (3) the result of factor analysis tells that the regional centrality of Yongcheng is the highest among the entire county-level cities in the east of Henan province which implies its potential to become a regional central city in east Henan; (4) and analysis based on gravity model indicates that Yongcheng holds a closer economic linkage with Huaibei and Xuzhou rather than Shangqiu, the prefectural level city in which it locates, as the city’s major directions of economic linkages are on its northeast.
