Based on the concept of people's city,a five-dimensional evaluation index system of livability in Chinese cities covering ecological environment,transportation,livelihood environment,public services,and living services was constructed.The spatial differences and temporal evolution patterns of livability levels of Chinese cities from 2000 to 2020 were examined using entropy weight method,Dagum Gini coefficient,and kernel density estimation method,and the driving factors of spatiotemporal differentiation were explored using geographic detectors.Results show that:(1)China's cities'livability has generally improved,displaying a pattern of"high in the east and low in the west,"with the average gap between the east and the west gradually widening;(2)Overall spatial differences in urban livability across the country have widened,with inter-regional differences being the primary source of urban livability differences,and intra-regional differences showing a decreasing pattern of"east-west-northeast-central".The distribution of urban livability across the country and regions demonstrates obvious extensibility,with differing polarization patterns and trends across different regions;(3)Spatial urbanization and government inputs emerge as the main drivers of spatial and temporal differences in urban livability,while the driving roles of residents'affluence and population urbanization are gradually increasing.The explanatory power of factor interactions surpasses that of single factors,with the main types being two-factor enhancement and nonlinear enhancement.
