Exploring the spatial correlation between accessibility to urban vibrancy centers and housing price from a time-dynamic perspective

Urban vibrancy is an important indicator of urban prosperity. Evaluating the correlation between urban vibrancy and housing prices is increasingly necessary. However, most studies have ignored the temporal characteristics of urban vibrancy and only considered its spatial nature. This study optimizes the identification model of urban vibrancy centers and proposes a novel model for evaluating the time-dynamic accessibility of urban vibrancy centers. The model takes into account real-time changes in travel costs and analyses its spatial correlation with housing prices. The case study of Chengdu shows significant variations in the spatiotemporal distribution of urban vibrancy centers. High-vibrancy areas are concentrated near commercial complexes. The time distribution of urban vibrancy accessibility is more concentrated at night (18:00-24:00), and the high-accessibility areas are located around the old city and the newly planned Central Business District in the south. Housing prices and urban vibrancy centers accessibility are mainly negatively correlated spatially. The study emphasizes the temporal nature of urban vibrancy and accessibility and enriches the evaluation model of urban vibrancy centers. It also contributes to the improvement of the framework of urban vibrancy research and deepens the understanding of the important variable of time in urban planning.

Automated summary

Urban vibrancy is a crucial factor in assessing urban prosperity. This study focuses on the relationship between urban vibrancy and housing prices, considering both spatial and temporal characteristics. By optimizing the identification model of urban vibrancy centers, a novel model for evaluating the time-dynamic accessibility of these centers is proposed. Results from the case study in Chengdu reveal significant variations in the spatiotemporal distribution of urban vibrancy centers, with high-vibrancy areas concentrated near commercial complexes. The study emphasizes the importance of considering the temporal nature of urban vibrancy and accessibility, contributing to the improvement of research frameworks and urban planning.
