本文以城市流描述城市的基本活动部分和外向功能,以城市流强度来描述中心城市对外服务能力大小,全面分析了我国中心城市生产性服务业对外服务能力的规模分布及格局变化。研究认为,生产性服务能力的规模递增趋势明显,全国性中心城市集聚与省域中心城市集聚并存。中心城市生产性服务能力高度集中在北京、上海和各省区的省会及副中心城市,生产性服务业与制造业呈现明显的生产性服务业中心集聚与制造业腹地生产的区域性空间组合关系。北京生产性服务功能在不断加强的同时,其制造功能在逐步外迁,长三角、珠三角、山东、福建等省区的中心城市生产性服务能力与制造功能增长较快,湖北、湖南和江西等省区接受沿海地区的产业转移,其生产性服务能力与制造功能也有相对较快的增长。

In this paper, we use the concept of urban flow to describe the basic economic activity and external function in a city, and use urban flow intensity represent the quantitative index of city external service capability. By this means, we comprehensive analysis the Chinese central cities producer service industry external service capabilities scale distributing and its spatial distribution change.The spatial distribution of the productive service capacity is eastern coastal cluster extent greater than inland area, economic developed area is higher than the less developed region, and national central cities agglomerate coexists with the provincial region central cities agglomerate. Central cities producer service capacities are highly concentrated in Beijing, Shanghai, provincial capital and its deputy central cities. Research shows, the producer service and manufacturing intensity has obvious regional spatial combination relations which producer service central agglomerate with the manufacturing hinterland product.
