城市的空间发展与经济重构有密切的关系,产业结构的变化是城市经济空间演化的直接动力。本研究分析了随就业结构变动,北京都市区不同部门就业空间分布的变化及对城市空间发展的影响。研究发现,就业结构变动显示出北京都市区产业结构在升级,就业正脱离第二产业和传统服务业,转向生产性服务业。同时,就业结构变动剧烈的行业,尤其是在就业结构中比重迅速增加的生产性服务业,其就业空间分布的变动也十分突出,表现出就业分布的空间转移和新的空间集聚,从而带来城市经济空间格局的重组。一方面,生产性服务业快速增长的地区总体就业增长也比较迅速,形成了新的就业集聚区,改变城市的空间结构;另一方面,生产性服务业就业的空间转移和集聚具有特定的区位指向,形成了专业化的地域分工格局。
The spatial development of cities has been influenced by economic restructuring, and the structural changes in urban economy are the driving forces for the evolvement of the spatial pattern of economic activities in cities. This study focuses on the changing intra-metropolitan spatial distribution of employment with economic restructuring in the Beijing metropolitan area. Based on the analysis using the economic census data of Beijing, we find the employment structure of the Beijing metropolitan area has changed evidently from 2004 to 2008, with the decrease of employment shares in manufacturing, construction and consumer services sectors, while the increase of employment shares in producer services sectors. Meanwhile, the spatial distributions of employment in the sectors of which the employment shares have changed greatly have also shifted dramatically. Especially the spatial distributions of producer services employment have changed greatly with evident geographical shift and reconcentration, which leads to the reorganization of the spatial economic pattern in the Beijing metropolitan area. On the one hand, new urban employment centers emerged where the producer services sectors grew rapidly, which has changed the spatial structure of the Beijing metropolitan area. On the other hand, producer services employment has spatially shifted and reconcentrated into distinct locations, which leads to the specialized territorial divisions of labor in the Beijing metropolitan area.
