【摘要】：航空运输企业是高排放高污染行业,研究其能源利用效率有着重要意义.基于SBM-DEA模型,利用2010年到2015年能源投入与能源产出的相关数据,对中国和欧盟共16家航空运输企业能源利用情况进行分析研究.结果表明,总体看欧盟航空运输企业能源效率优于中国企业;动态Malmquist指数分析结果表明,中国航空企业全要素生产率波动较大,欧盟企业则更为平缓,中国企业的全要素生产率与综合效率变化指数的变动情况基本保持一致,而欧盟企业的全要素生产率则与技术进步变化指数波动保持一致;在不考虑环境因素情况下会高估TFP增长率以及技术进步增长率.中国企业应加大技术投入和管理,才能有效提升能源利用效率及全要素生产率.
[Abstract]:Air transportation enterprises are high emission and high pollution industries, so it is of great significance to study their energy efficiency. Based on SBM-DEA model, the energy utilization of 16 air transport enterprises in China and the European Union is analyzed and studied by using the relevant data of energy input and energy output from 2010 to 2015. The results show that the energy efficiency of EU air transport enterprises is better than that of Chinese enterprises as a whole. The results of dynamic Malmquist index analysis show that the total factor productivity of Chinese aviation enterprises fluctuates greatly, while that of EU enterprises is smoother, and the changes of total factor productivity and comprehensive efficiency change index of Chinese enterprises are basically consistent. The total factor productivity of EU enterprises is consistent with the fluctuation of technological progress change index. TFP growth rate and technological progress growth rate will be overestimated without considering environmental factors. Chinese enterprises should increase technology investment and management in order to effectively improve energy efficiency and total factor productivity.
