基于DEA模型的城市地铁交通系统运营效率研究

以20个地铁交通系统已正式投入运营的城市为研究对象，从投入产出方面构建评价城市地铁交通系统运营效率的指标体系，借助数据包络分析模型将20个城市地铁交通系统运营效率划分为高效率水平城市、较高效率水平城市和低效率水平城市3个层级。此外，基于投入产出的视角，分析各城市地铁交通系统当前的投入产出特征，找出当前地铁交通系统存在的不足，为相关部门科学合理地决策提供参考。

DEA model based operation efficiency of an urban metro transit system

We construct an index system evaluating urban subway operating efficiency from input and output with 20 running urban subway traffic systems as subjects. We further divide their operation efficiency into high,higher and low efficient levels based on data envelop analysis (DEA) model.Moreover, we also analyze current input and output characteristics for these urban subway traffic systems, and find their existing deficiency.It provides the reference for relative departments to make scientific decision.
