摘要

区位不可替代性的概念是指一个区位在提供服务和满足需求方面具有其他区位无法取代的独特性。尽管学者们对研究区位不可替代性表现出了极大的热情,但对其进行精确测量并理解城市形态的影响,还没有通过实证研究进行深入探讨。本研究选择中国深圳作为研究区域。首先,利用手机数据,采用以地理流量为核心的 I 指数来衡量区位的不可替代性。随后,从人口、建筑容量、公共服务和区位条件等角度分析了与城市形态相关的因素。最后,构建了一个地理和时间加权回归模型(GTWR),以探讨不可替代性与城市形态之间的时空关系。研究表明,考虑流量和距离的 I 指数可以有效地衡量地点的不可替代性。GTWR 的结果表明,地点的不可替代性及其影响因素呈现出时空异质性。这项研究从概念和方法上推进了我们对区位不可替代性与城市形态之间关系的理解。研究结果对城市设计和规划具有实际意义,包括城市空间优化、设施公平和缓解交通拥堵。

Unraveling the impact of urban form on location's irreplaceability: An analysis from the perspective of spatiotemporal heterogeneity
The concept of a location's irreplaceability pertains to its unique characteristics that make it challenging for other locations to replace in terms of providing services and meeting needs. While scholars have shown great enthusiasm for studying location irreplaceability, accurately measuring it and understanding the effects of urban form have not been thoroughly explored through empirical research. This study selects Shenzhen, China, as the study area. First, the I‐index, which focuses on geographic flow, is utilized to measure the location's irreplaceability using mobile phone data. Subsequently, the factors related to urban form are analyzed from the perspectives of demography, building capacity, public services, and the location's conditions. Finally, a geographically and temporally weighted regression model (GTWR) is constructed to explore the spatiotemporal relationships between irreplaceability and urban form. The study demonstrates that the I‐index, considering flow volume and distance, can effectively measure the location's irreplaceability. The results of GTWR indicate that the location's irreplaceability and its influencing factors exhibit spatiotemporal heterogeneity. This study advances our understanding of the relationships between location irreplaceability and urban form both conceptually and methodologically. The findings have practical implications for urban design and planning, including urban space optimization, facility equity, and the alleviation of traffic congestion.
