摘　　要：分析铁路客运站经济效益和旅客舒适度的影响因素,确定输出指标,以铁路客运站的各种能耗因素作为输入指标,用数据包络分析(DEA)模型进行线性规划求解,得出了客运站的总体效率、纯技术效率、规模效率和相对排序,提出了使非DEA有效的客运站达到DEA有效的途径。并通过比较各有效客运站能效的横切效率的大小,得出所有客运站能效利用情况的最终排序。对铁路客运站能效提高提出有针对性的建议,以期为改进和提高铁路运输质量和增强铁路运输的综合竞争力提供参考依据。The objective of this research is to evaluate the energy efficiency for a railway station, based on an energy efficiency analysis. Firstly, the influencing factors of passenger＇s comfort extent in the waiting environment and the economic benefit of the railway station are analyzed and an output index system is established. Secondly, various energy consumption factors form the input index system. On the basis of DEA model, with linear programming methods, the total efficiency, the pure technology efficiency, tile scale efficiency and the relative order are obtained. Methods are proposed to turn a non-DEA efficient railway station into a DEA efficient one. Then the crosscut efficiency between different railway stations are compared. According to the results, the final ordered list of all stations based on energy efficiency and passengers＇ comfort extent is obtained, with some important and useful suggestions for improving the railway station energy efficiency. Some proposals are given for improving the transportation quality and comprehensive competitiveness.
