Abstract
The rapid development of air transportation brings serious environmental concerns. Under environmental constrains, using SBM-DEA model with undesirable outputs researches on the environmental efficiency of China's airlines from 2012 to 2014 and influencing factors of environmental efficiency are then explored using a Tobit mode. The results show that, during 2012 to 2014, the environmental efficiency of China's airlines show a decreasing trend. And the gap of environmental efficiency among airlines is enlarging year by year. In addition, the regression results show that environmental regulation had a passive effect on environmental efficiency of airlines in China. R&D investment/load factor/goods delivery rate and net profit rate/environmental regulation (-1) have a positive effect on environmental efficiency of airlines in China. Finally, combined with the research results of this paper, the author puts forward the suggestions from the points of mining the potential of energy saving and emission reduction in airlines and R&D investment.
