自20世纪20年代起CBD就一直是国外学者们的关注重点,自20世纪80年代后期就业次中心也成了西欧和北美学者们的研究热点。本文试图使用2004年和2008年广州市两次经济普查的分街道就业人员数据,以及就业人员密度方法来定义CBD和就业次中心,并运用空间分析法、比较分析法和图形分析法研究广州市就业次中心和CBD动态发展。研究结果显示,从2004～2008年广州市就业次中心和CBD的数量没有发生变化,但各个街道的就业人员密度有所增加,就业次中心和CBD的服务功能也得到增强;就业次中心的动力机制由以第二产业为主转向以第三产业产业为主,双核CBD逐渐连接成单核CBD,并呈现向各个方向扩散之势。
Since the 1920s, CBD has been the focus of foreign scholars. Since the employment sub-center in the late 1980s, it has also become a research focus of scholars in Western Europe and North America. This paper tries to define the CBD and employment sub-centers by using the data of sub-street employees and the density of employed persons in the two economic censuses of Guangzhou in 2004 and 2008, and uses the methods of spatial analysis, comparative analysis and graphic analysis to study Guangzhou Employment sub-center and CBD dynamic development. The results show that there has been no change in the number of Employment Sub-centers and CBDs in Guangzhou from 2004 to 2008, but the density of employed persons in each street has increased, and the service functions of Employment Sub-centers and CBD have also been enhanced. The employment sub-centers' motivation The mechanism is mainly shifted from the secondary industry to the tertiary industry, and the dual-core CBD is gradually connected into a single nuclear CBD, showing a tendency to spread in all directions.
