• 摘要： 研究基于夜间灯光数据，深入探讨了1999—2022年广西范围内111个县域的城市增长和收缩的时空动态变化特征，并系统分析广西县域城市增长和收缩的驱动力。研究显示，广西城市增长与收缩呈现交替变化，存在显著的两极分化特性，其中长期增长型城市占据了主导位置。城市增长的轨迹保持稳定，而城市收缩的现象则显现出从西至东、由北往南的空间变换。城市增长结构以带状为主，收缩结构以点状为主。政策因素和社会经济因素是主要驱动因素，而交通建设对广西县域城市增长具有显著驱动力。研究建议优化区域政策，加强交通基建，促进产业升级，实施差异化策略，保护生态环境，提升公共服务，以促进广西县域城市高质量发展，推动城市增长与收缩间的正向互动，旨在提升区域的整体竞争实力。
• Based on the nighttime light data, this paper deeply discusses the spatial and temporal dynamic characteristics of urban growth and shrinkage in 111 counties in Guangxi from 1999 to 2022, and systematically analyzes the driving forces of urban growth and shrinkage in counties in Guangxi. The research shows that the growth and contraction of cities in Guangxi show alternating changes, and there is a trend of polarization, with long-term growth cities dominating. The urban growth trajectory is stable, while the urban contraction trajectory shows a shift from west to east and from north to south. The urban growth structure is dominated by bands, and the shrinkage structure is dominated by dots. Policy factors and socio-economic factors are the main driving factors, and traffic construction has a significant driving force for the growth of county cities in Guangxi. The study suggests optimizing regional policies, strengthening transportation infrastructure, promoting industrial upgrading, implementing differentiated strategies, protecting the ecological environment, and improving public services to promote the high-quality development of county cities in Guangxi, realize the positive interaction between urban growth and contraction, and enhance the overall competitiveness of the region.
