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