本文将污染治理成本定义为不期望产出自由处置时的产出与不期望产出弱处置时的产出之比。在此基础上，提出了一个动态环境DEA模型，将污染治理成本变化指标分解为技术变化指标、投入水平变化指标和非期望产出变化指标。基于2008 - 2014年全球18家大型航空公司的实际数据进行了实证研究。主要发现有：（1）达美航空公司的PAC变动幅度最大。(2)大多数航空公司的PAC都有所下降。(3)2008年的金融危机和生物燃料飞机的应用对PAC的变化产生了重要影响。
In this paper, we define the pollution abatement cost (PAC) as the ratio of the outputs when the undesirable outputs are freely disposed to the outputs when the undesirable outputs are weakly disposed. Then we propose a Dynamic Environmental DEA model to calculate the pollution abatement cost change indexes, which are decomposed into technical change index, input level change index and undesirable output production change index. An empirical study is done based on the actual data of 18 large global airlines from 2008 to 2014. The main findings are: (1) Delta Air Lines has the largest PAC changes. (2) Most airlines' PACs have decreased. (3) The financial crisis of 2008 and the application of biofuel aircrafts have important impacts on the PAC change.
