Efficient utilization of land resources is fundamental for achieving sustainable urban development. Utilizing the urban land use efficiency (ULUE) framework for production-living-ecological (PLE) functions, this study establishes three key indicators to evaluate the sustainable development status of each dimension. The indicator system was applied to 433 Chinese cities to analyze the temporal and spatial changes in urban sustainable development from 2000 to 2020. Research findings reveal significant disparities in sustainable urban development levels across Chinese regions from 2000 to 2020, following a consistent trend: Eastern > Western > Central > Northeast. The ULUE for living and production functions in Chinese cities experienced an obvious decline from 2015 to 2020. This indicates that urban land expansion in most Chinese cities surpassed population growth, accompanied by a noticeable reduction in economic growth rates. Since 2010, the ULUE for ecological function has improved significantly in Eastern region, reflecting a shift in development priorities towards a green approach rooted in ecological conservation principles. However, the ULUE in Northeastern cities has declined, placing this region at a competitive disadvantage due to the dual challenges of declining population and economic recession. Since 2015, urban land expansion in Central Chinese cities has significantly outpaced other regions, resulting in extensive land use, posing challenges to resource planning and management. Smaller cities, in contrast to their larger counterparts, face a lower overall sustainability level and encounter more acute challenges related to population migration and economic transition. The analysis offers valuable insights and policy recommendations to enhance sustainability in developing regions.
