利用生产性服务业的空间布局研究
中心城区尺度多中心性可以探析城市内部的
功能空间结构。本文选取长春市中心城区范
围内的保险、广告、会计、科技、律师、物流、
银行7种生产性服务业的POI数据进行核密
度分析,采用空间主成分分析法对生产性服
务业空间布局进行综合分析,利用城市网络
分析工具U NA测度长春市中心城区交通网
络中心性,检验其与生产性服务业的相关关
系。研究结果发现长春市中心城区范围生产
性服务业多中心呈分级圈层分布;生产性服
务业部分中心与城市商业中心吻合;传统商
务中心对生产性服务业的影响较大,老城区
的老商业中心易出现生产性服务业中心;生产
性服务业多中心与交通网络中心性存在明显
正相关,生产性服务业沿城市主要道路的集
聚明显。 |

Abstract: |
Using the spatial layout of producer services, the central city scale polycentricity study
can explore the functional spatial structure of city inside. The POI data of 7 producer services,
namely insurance, advertising, accounting, science and technology, lawyers, logistics and
banks are selected for kernel density analysis. The results are analyzed by the spatial principal
component analysis to get the polycentric comprehensive analysis map of producer services. The
urban network analysis tool UNA is used to measure the centrality of the traffi c network in the
central city of Changchun, and to test its correlation with producer services. The results show that
the polycentricity of productive service industry in the central city of Changchun is distributed
in a hierarchical circle; the partial center of the productive service industry is consistent with
the urban commercial center; traditional business centers have a greater impact on producer
services, while the old business centers are prone to producer services; there is a strong positive
correlation between the city polycentricity and the traffi c network centrality, and the productive
service industry is obviously gathered along the main roads of the city. |
