摘要
科学合理的城市内部空间结构可实现兼顾效率与宜居的城市治理目标。本文利用多源大数据定量研究了后工业化阶段城市紧凑发展的消费者福利效应和机制。结果发现,紧凑的城市空间结构对消费多样性具有显著的正向影响,“以人民为中心”的城市更新模式可强化上述影响。机制分析结果表明,紧凑的城市内部空间结构通过增加人口密度、增加人流密度以及促进零售商集聚3种机制从供需两端提升城市消费多样性。此外,城市内部空间结构对消费多样性的影响还存在显著的空间衰减效应,验证了后工业化阶段服务业主导的大城市市中心密度的重要性。
A scientifically sound urban spatial structure within a city can effectively balance urban governance goals,targeting both efficiency and liveability.This study leverages multi-source big data in China to quantitatively explore the consumer welfare effects and mechanisms associated with compact urban development in the post-industrial era.The findings reveal that a compact urban layout significantly boosts consumption diversity.Moreover,a“people-centred”approach to urban renewal can amplify this effect.Analysis of the underlying mechanisms indicates that a compact urban spatial structure augments consumption diversity from both the supply and demand sides by increasing population density and the number of pedestrians and fostering clusters of retail.The research also reveals a pronounced spatial decay effect in the influence of urban spatial structure on consumption diversity,highlighting the pivotal role of service sector-dominated urban centres'density in the postindustrial era.
