以就业人数为基础数据,运用全局主成分分析、空间基尼系数、克鲁格曼专业化指数、区位熵、转移一份额分析等方法,测度了京津冀都市圈主要服务业集聚的整体状况、行业特征以及各城市分工程度和专门化率。空间上整体呈现出典型非均衡的单中心、大梯度等级化集聚的发展态势;商务服务、信息服务、科技服务和房地产等行业的专业化优势最明显;各城市主要服务业内部的结构差异较大,专业化分工也较明显;北京的高端行业具有绝对的竞争优势和行业优势,其他9个城市也各有一定的比较优势。服务业集聚的驱动力包括专业化分工、竞争与协作和网络创新等自组织及政府干预等他组织2种作用机制。
Using employment numbers as basic data and applying generalized principal component analysis, spatial Gini-eoefficient, Krugman specialization index, location quotient, shift-share analysis and other methods, the article measured the model of locality distribution, the industrial characteristics, the specialized rate of every city's industry and its comparative advantage about the major service in Beijing-Tianjin-Hebei Metropolitan Region. The general spatial distribution showed itself the situation of typical non-balancing single center and large gradient level of development : those knowledge-intensive, technology-intensive and capital-intensive industries such as business services, information services, technology services and real estate industry are most outstanding in our nation ; the structure differences of major service' s internal industry are large ; the division of labor based on speciali- zation about each city are distinctive; the high-end services of Beijing had absolute competition advantage and industrial advantage, the other 9 cities also had some comparative advantage. The drive power of services agglomera- tion includes self-organizing and other-organizing.
