摘要
利用兴趣点(point of interest,POI)数据对小尺度经济活动的有效描述功能,以西安市为例,探究轨道交通站域生产性服务业的空间分布特征。在提出站域范围确定方法并整合城市内部生产性服务业业态类型的基础上,通过区位商测度揭示6类业态的站域空间分布整体特征及局域特征,借助二阶偏相关分析研判站域物质空间环境对各类业态分布强度的影响,并解译蕴含的空间分布影响机制。结果表明:(1)生产性服务业业态的站域空间分布大都呈现相对全市总体占优的特征,而各类业态的局域空间分布特征又可细分为向心型、离心型和过渡型;(2)在轨道交通站域内,职住空间的多样性促进大部分业态的站域集中分布,开敞空间的开敞度抑制大部分业态的站域集中分布,道路空间的路网密度则仅对部分业态的空间分布产生较弱的正向影响;(3)西安市轨道交通站域生产性服务业空间分布的影响机制有基于强烈实体产业关联的互补性机制、基于空间资源博弈的竞争性机制、基于特定部门非典型需求的有选择支持性机制。
The spatial distribution of producer services in metro station areas in Xi′an city and corresponding acting mechanisms are studied through the effective description function of point of interest(POI) data to economic activities at small spatial scale. The scope determining method of a metro station area is put forward and the producer services sectors thriving within inner city are integrated into 6 categories of businesses. Then the general characteristics of spatial distribution of each category are analyzed and compared by location quotient calculation, as well as the local ones at the same time. Moreover, second-order partial correlation analysis is employed to explain the influences on spatial distribution concentrations of 6 categories in metro station areas due to their material space environments, while some mechanisms can be concluded later with the spatial distribution outcomes of Xi′an city. The results indicate that the general distribution characteristics in the whole city is more concentrations of producer services happened in metro station areas than other places and there are still 3 patterns of local distribution characteristics for 6 categories of businesses, including centripetal ones, centrifugal ones and sandwich ones. The diversity increasing of space for residence and employment in metro station areas surely contributes to the spatial concentrating of most categories of producer services, but more open space makes obstacles to their concentrating in the same situation. Furthermore, the increasing of urban road density of traffic space in metro station areas only influences the distributing of a few categories and the influential effects are also weak.Three influential mechanisms of spatial distribution for producer services in metro station areas of Xi′an city can be put forward, including complementary mechanism owing to intensive entity-relationship among correlative industries, competitive mechanism owing to resources contention of material space, selective supporting mechanism owing to atypical demands from specific industrial sectors.
