城市路网中心性与创新空间布局的相关性研究——以杭州市区为例

A Study on the Correlation Between the Urban Road Network Centrality and the Layout of the Innovation Space:Taking Hangzhou City as an Example

文章以杭州市区为例,结合POI数据与道路网络矢量数据,利用多中心评价模型、核密度估计与Person相关系数法,探究城市路网中心性与创新空间布局的相关性。研究表明:(1)杭州市区内各类创新空间与城市路网中心性均具有显著的正相关关系;(2)创新企业空间与路网中心性的相关性最强,而创新知识空间与路网中心性的相关性最弱;(3)与直达中心性和介数中心性相比,道路网络的临近中心性与创新空间布局的关系最为紧密。

Taking Hangzhou City as an example,by combining POI data and road network vector data with polycentric evaluation model,kernel density estimation and Person correlation coefficient method,this paper explores the correlation between urban road network centrality and innovation space layout.The study shows that:(1)all types of innovation spaces in Hangzhou City have a significant positive correlation with the centrality of the urban road network;(2)the correlation between innovative enterprise space and road network centrality is the strongest,while the correlation between innovative knowledge space and road network centrality is the weakest;(3)compared with direct centrality and meso-centrality,the proximity centrality of road network has the strongest relationship with the layout of innovative space.
