摘要
本文利用大数据挖掘技术、地理信息技术构建上海的网格化数据集,实证检验街区层面的道路密度对消费活力的影响。研究发现,更高的路网密度提升了服务消费的数量、质量和多样性,等级低的路网其密度越高越有利于消费活力的提升,上述效应呈现显著的“中心-外围”特征。机制分析表明,提升道路连通性通过影响人流量增强消费活力,这种机制在等级低、步行友好的道路中更加显著。进一步分析显示,消费活力会资本化到房价和住宅租金中。
The influence of road density on consumption vitality is tested,using big data.The results show that the increase of road density will lead to the improvement of consumption quantity,quality and diversity,and the lower grade of the road network density is,the better the consumption vitality is.This effect shows a significant“center-periphery”characteristic.The mechanism shows that higher road connectivity increases consumption vitality by affecting the number of abortions,which is more significant in the low-grade roads.The improvement of consumption vitality will be significantly capitalized into the local housing price and residential rents.
