城市群生产性服务业的空间集聚特征——以珠三角城市群为例

Features of spatial agglomeration of productive services of urban agglomeration:a case study of urban agglomerations of the Pearl Delta Area

基于2007-2013年珠三角地区生产性服务业的相关数据,运用空间基尼系数、赫芬代尔指数和EG指数,对城市群生产性服务业的空间集聚特征进行了测度。结果显示:城市群生产性服务业的区域和空间集聚程度及变化趋势基本一致,但与行业内企业的集中特征不一致,行业内企业的集中程度呈总体递减趋势;生产性服务业集聚分布水平不均衡,中心城市的生产性服务业通常占有较大市场份额;城市群内各城市的生产性服务业空间集聚变化特征总体一致,行业集聚水平的差异使得各城市各具发展优势。

Based on the data of producer services in Pearl River Delta region from 2007 to 2013, this essay measures the overall characteristics of spatial agglomeration about the pro- ducer services by using the methods of the Spatial Gini - coeffi- cient, Herfindahl Index and EG Index. The results are shown as follows ： the area of urban agglomeration about the producer serv- ices are basically identical to spatial agglomeration degree and variation tendency, but disaccords with the characteristics of en- terprises concentration within the industry, whieh generally pres- ents a declining trend. The concentration of producer services agglomeration distributes unevenly, in which producer services in central city occupies a large share of market; the variation tendencies of the producer service＇ spatial agglomeration in the cities within the urban agglomerations are generally consistent. The differences of industry agglomeration guarantee each city own development advantages.
