自20世纪90年代经济改革以来，中国城市空间增长发生了巨大变化。基于1990 - 2008年中国52个大城市的土地利用影像和相关社会经济统计数据，运用空间计量经济学和拓扑分析等方法，分析了大城市空间增长的特征和成因。研究结果表明：2000年以后，城市空间总体增长迅速，但增长速度减缓，人口规模等级下降;城市空间要素增长趋势趋向于新的、多样化;城市空间结构增长呈现带状和多中心格局;空间形态增长呈现分散和破碎化格局;城市空间增长模式以轴向和跳跃式为主。中国大城市空间增长的主要原因是经济的快速增长、城市化的快速发展和政府的GDP政绩观。最后，本文认为中国大城市空间增长的主要问题是规模增长过快、结构分散、形态破碎。因此，城市增长政策应注重规模控制、结构优化和空间紧凑。
Since China's economic reform in the post-1990s, urban spatial growth has experienced tremendous changes. By using methods, such as spatial econometrics and topological analysis, this paper analyzes the features and causes of spatial growth in 52 Chinese metropolises based on images of land use and relevant socio-economic statistical data from 1990 to 2008. The research results indicate that: urban space grows rapidly especially after 2000 in general but shows a decelerating trend with a lowering rank in the population-size hierarchy; the growth trend of urban spatial elements inclines to be new and diverse; the growth of urban spatial structure shows a zonary and polycentric pattern; the growth of spatial morphology displays a pattern of decentralization and fragmentation; the urban spatial growth patterns are mainly axial and jumping oriented. Furthermore, we find that the major causes of urban spatial growth in Chinese metropolises are fast economic growth, rapid urbanization and GDP-oriented view of achievement in city government. Finally, the paper argues that the main problems of urban spatial growth in Chinese metropolises are excessive growth of the scale, scattered structure and fragmented morphology. Thus we suggest that the urban growth policy should focus on scale control, structure optimization and spatial compactness.
