Sustainable urban development focuses on enhancing urban well-being, while also balancing the demands of urban social and economic development, natural resource consumption, and environmental pollution. This work used general data envelopment analysis to assess the urban sustainability efficiency (USE) and sustainability potential (SP) in Lanzhou and Xiamen, two cities that are characteristic of urban areas in western and eastern China. The assessment indicator system included important natural and urban welfare factors as input and output indices, respectively. The results showed that overall urban sustainability efficiency increased in Lanzhou and Xiamen from 1985 to 2010, but that the sustainability of natural resources clearly decreased. The urban sustainability efficiency of Xiamen was higher than that of Lanzhou, and the sustainability potential of Xiamen was lower than that of Lanzhou; this indicates that Xiamen performed better in terms of urban sustainable development. The urban sustainability efficiency in Xiamen has increased with increasing urban population, and the rate and scale of economic development have been higher than in Lanzhou. The assessment and analysis performed in this study show that cities with different natural resources and development characteristics have different forms, patterns, and trajectories of sustainable development.
可持续城市发展注重提升城市福祉，同时平衡城市社会经济发展、自然资源消耗和环境污染等需求。本研究采用一般数据包络分析方法，对中国西部和东部具有城市代表性的两个城市——兰州和厦门的城市可持续发展效率（USE）和可持续发展潜力（SP）进行评估。评估指标体系分别将重要的自然和城市福祉因素作为投入和产出指标。结果表明，1985年至2010年期间，兰州和厦门的城市可持续发展效率总体呈上升趋势，但自然资源的可持续性明显下降。厦门的城市可持续发展效率高于兰州，而厦门的可持续发展潜力低于兰州；这表明厦门在城市可持续发展方面表现更好。厦门的城市可持续发展效率随着城市人口的增加而提高，经济发展速度和规模高于兰州。本研究进行的评估与分析表明，具有不同自然资源和发展特征的城市，其可持续发展的形式、模式和轨迹各不相同。
