摘要
非正规经济已成为我国重要的城市景观,本文以北京朝阳区为研究范围,利用流动商贩和POI等大数据,探究城市建成环境对摊贩空间分布的影响。研究表明:(1)高密度的消费需求是引致流动商贩集聚的首要原因,尤其是在正规商业较为缺乏的区域,流动商贩的高发态势尤为明显,政府管制没有也无法遏制这一非正规经济现象。(2)相较于道路网络的通达性,街区尺度的宜人性和城市功能的多样性更为显著地促进了商贩集聚,因此小巷支路是疏导区选址的理想场所。(3)不同用地类型对各时段的商贩空间分布具有差异化影响,可考虑在特定用地周边设置固定型、临时型等多种形式的疏导区,以实现各类城市功能的兼容并包。
Informal economy has become important urban landscape, and informal employment has turned into a significant form of attracting urban employment in China since reform and opening. However, because of limited data related to the hidden characteristics of informal economic activities, the subject of urban geography had little cognition of its spatial distribution law inside city, especially at the macro dimension and via quantitative method. Therefore, when the informal commerce encountered conflicts with urban offical man- agement, where to construct vending areas was still tough problems for city management after realizing the zero tolerance policy was controversial and ineffective. In order to fill in this gap and propose suggestion to vending site selection, this thesis focused on Chaoyang district in Beijing and utilized big data of street vend- ing, point of intersts and road network to explore the influence of built environment on vendors＇ distribution. According to the spatial distribution of mobile traders, its density as a whole showed a gradual decline trend from urban core to suburbs, especially around the third-ring road from morning to afternoon. Until the late market, the flow of traders began to spread to some outer enclaves. The research demonstrated that high den- sity of consumption demand was vital reason for vendors＇ agglomeration in different periods, especially around places with little formal commerce. Now that ＇Zero tolerance＇ urban management was unable to stem vendors＇ activity, thus could be seen the necessity of vending sites.
