Evaluation of urban vitality in China using the vital triangle framework
Urban vitality stands as a pivotal driver underpinning the healthy and sustainable evolution of cities,exerting a direct influence on people's welfare,corporate advancement,and urban competitiveness.Adopting an urban organism viewpoint,we draw inspiration from the"vitality triangle"conceptual model and selected specific evaluation indicators from the three key aspects of growth metabolism,diversity,and mobility.The evaluation indicator system consists of six pivotal dimensions:population,economy,society,governance,environment,and external links.We assessed the vitality levels of 290 cities in China at the prefecture level and above by integrating a variety of data,including points of interest,social platforms,nighttime lighting,Baidu Index,population migration,corporate information,environmental monitoring,land use,population census,and statistics.The study revealed that high-vitality cities are mostly concentrated in the Yangtze River Delta region,followed by urban agglomeration areas and provincial capitals.Low-vitality cities are widely distributed in the Northeast region,while cities in the North China Plain area generally exhibit moderate to low levels of vitality.China's urban vitality scores adhere to a power law distribution,accentuating the dominance of a limited subset of cities functioning at heightened vitality levels,while the majority of urban centers demonstrate relatively subdued vitality levels.Cities with large population sizes tend to be more vibrant.Development across the six dimensions showed synergistic effects,displaying spatial variation and agglomeration.Based on dimension scores,Chinese cities fall into five types:high overall vitality,moderately high overall vitality,moderately low overall vitality,government-oriented vitality,and environment-oriented vitality.This research represents a significant contribution to the framework of urban vitality studies,offering a guidance for the advancement and high-quality development of urban vitality in Chinese cities in the post-pandemic context.
