【摘要】：航空运输企业发展带来的环境问题成为人们关注的焦点.本文从环境约束治理视角,运用SBM-DEA非期望产出模型研究中国航空企业2012—2014年环境效率,并借助Tobit模型分析了影响环境效率的主要因素.结果表明,2012—2014年期间,整体上中国航空企业环境效率呈现出递减的趋势,并且航空企业之间的环境效率差距在逐年拉大.另外,Tobit回归分析结果得出当期环境规制与航空企业环境效率显著负相关,而研发投入、航班客座率、货邮运载率、净利润率、滞后1期环境规制与航空企业环境效率显著正相关.最后,我们从挖掘航空企业自身节能减排潜力、研发投入角度给出了中国航空企业环境效率改进的政策建议.
[Abstract]:Environmental problems brought by the development of air transport enterprises have become the focus of attention. From the perspective of environmental constraint governance, this paper studies the environmental efficiency of Chinese aviation enterprises in 2012-2014 by using SBM-DEA non-expected output model, and analyzes the main factors affecting environmental efficiency by means of Tobit model. The results show that the environmental efficiency of Chinese aviation enterprises is decreasing in the period of 2012-2014, and the gap between them is widening year by year. In addition, the results of Tobit regression analysis show that the current environmental regulation and environmental efficiency of aviation enterprises are significantly negative correlation, while R & D investment, flight passenger rate, freight delivery rate, net profit rate, There is a significant positive correlation between environmental regulation and environmental efficiency of aviation enterprises. Finally, from the perspective of tapping the potential of energy saving and emission reduction of aviation enterprises themselves, we give some policy suggestions for improving the environmental efficiency of Chinese aviation enterprises from the point of view of R & D investment.
