摘要：

以DEA模型和Malmqusit全要素生产率指数为理论工具,将铁路客运与货运、产出阶段与创收阶段纳入统一研究框架,建立"双活动—双阶段"效率分析框架,系统地考察中国铁路运输的生产效率与生产力。研究发现:虽然中国铁路效率世界第一,但就内部效率而言,客运综合效率高于货运综合效率,且仍有较大的提升空间;客运和货运的产出效率均明显高于创收效率,创收能力低下是铁路运输发展的短板;铁路发展呈现区域不平衡特点;客运全要素生产率呈上升趋势,产出阶段来源于技术效率改善和技术进步双重贡献,创收阶段主要得益于技术进步;货运全要素生产率有所提升,但主要来自技术进步的贡献,产出效率和创收效率均有所衰退;各铁路局的效率状况不同,效率优化路径各有差异。
