Abstract: The aviation industry's carbon emissions have aroused a wide concern as the global airlines had discharged about 915 million tons CO2 in 2019. The airlines have taken many measures to control emissions. However, existing studies have not considered the role of cooperation or competition in evaluating the effects of controlling emissions. We build a dynamic structure for airline environmental efficiency and two Dynamic Benevolent Environmental DEA Cross-efficiency model and Dynamic Aggressive Environmental DEA Cross-efficiency model to evaluate the airline dynamic environmental efficiency. Then we apply a cross efficiency distinguishing method to reflect the degree of cooperation and competition in airline environmental efficiency. Then, the models are applied to assess the efficiency of 29 global airlines from 2010 to 2016. The empirical analysis results confirm the reasonability of the models. The results show that most airlines have a relationship in which the cooperation is larger than the competition in 2010 and 2012, but they have a relationship that both competition and cooperation coexist in other years.
