次级中心城市选择中的区域经济意义——以环京津地区为例

河北省环京津地区主要由唐山、秦皇岛、保定、廊坊、承德、张家口和沧州7个地级市组成。这些地区与北京、天津存在着明显的区域发展不均衡现象。本文根据环京津地区各城市的经济发展状况、区位条件和对外开放环境建立了一套综合评价系统,采用因子分析和威尔逊模型等方法对该地区的各城市进行了综合排名,最终确定了唐山和保定为环京津地区的次级中心城市,从而形成了该地区"1+2"的区域经济发展战略格局。

The area around Beijing-Tianjin region in Hebei Province is mainly composed of seven cities which are Tangshan, Qin- huangdao, Baoding, Langfang, Chengde, Cangzhou and Zhangjiakou. There is an extremely unbalanced development between these cities and Beijing-Tianjin. Therefore, according to the economic development, location condition and opening-up en- vironment of these cities, this article establishes a comprehensive evaluation system. By means of factor analysis and the Wilson model, we finally determine Tangshan and Baoding as sub-regional centers around Beijing-Tianjin region in Hebei Province, thus forming the strategic pattern of regional economic development of this region.
