Abstract

We build a dynamic structure for airline environmental efficiency and propose the Dynamic Benevolent Environmental DEA Cross-efficiency model and Dynamic Aggressive Environmental DEA Cross-efficiency model to explore whether cooperation or competition can reflect the airline dynamic environmental efficiency in the past few years. Then, the models are applied to evaluate the efficiencies of 29 international airlines from 2010 to 2016. The results demonstrate that cooperation is more likely to unfold the benchmarking airlines than the competition, but competition is more likely to embody the airline with the lowest environmental efficiency.

摘要

我们构建了航空公司环境效率的动态结构，提出了Dynamic Benevolent Environmental DEA Cross-efficiency model和Dynamic Aggressive Environmental DEA Cross-efficiency model，以探索合作或竞争是否能反映过去几年航空公司的动态环境效率。然后，应用该模型对29家国际航空公司2010-2016年的效率进行评估。结果表明，合作比竞争更有可能展现标杆航空公司，但竞争更有可能体现环境效率最低的航空公司.
