电商时代大城市商业布局的时空演变特征与趋势——基于多期POI数据

Spatial-temporal Evolution Characteristics and Trends of Commercial Layout of Metropolis in the E-commerce Era——Based on Multi-period POI Data

电子商务对大城市商业空间布局产生了深远影响。以广州为例,基于2015年、2017年、2019年多期城市商业网点POI数据,采用GIS空间分析、核密度估计法探讨大城市商业布局时空演变特征。结果表明:(1)2015—2019年广州城市多中心商业空间发展格局更加明显,不同商业中心区网点集聚程度发生变动,部分商业中心区网点集聚水平进一步提升,部分商业中心区网点集聚程度有所弱化。(2)电商时代背景下,不同商业业态网点规模变化、商业布局演变特征存在差异,购物服务类网点规模呈现先低速增长后加速增长的特点,空间集聚特征明显;休闲娱乐、餐饮服务等服务消费类网点规模呈平稳增长趋势,空间布局均衡化趋势明显。

E-commerce had a profound impact on commercial spatial layout of metropolis.With Guangzhou as the case,this paper explored the spatial-temporal evolution characteristics of the commercial layout of metropolis through GIS spatial analysis and Kernel density estimation,based on the multi-period POI data of urban commercial outlets in 2015,2017 and 2019.The results showed that:During 2015-2019,Guangzhou took on a more obvious multi-center commercial space development pattern.Changes occurred to the level of agglomeration of outlets in different central business districts,with the level of some outlets further improved and that of some others slightly weakened.Under the background of the e-commerce era,there were changes in the size of outlets for some business formats,so were the evolution characteristics of the commercial layout.The size of shopping service outlets witnessed low-speed growth first and then accelerated growth,featuring obvious spatial agglomeration.And the size of outlets in the consumption category such as leisure and entertainment,catering service,and other services tended to grow stably,with a clear trend of spatial layout equilibrium.
