Will airline efficiency be affected by 'Carbon Neutral Growth from 2020' strategy? Evidences from 29 international airlines

摘要

In this paper, the impact of the "Carbon Neutral Growth from 2020" (CNG2020) strategy on airline efficiency is analyzed based on the predicted data of 29 international airlines during 2021-2023. The data is predicted through neural network. Following the principle of CNG2020 strategy, we calculate the emission limit for each airline. Two models, Network Range Adjusted Measure with natural disposability and Network Range Adjusted Measure with managerial disposability, are proposed to discuss the efficiency change when the CNG2020 strategy is considered. The following findings are gotten: 1. Under natural disposability, the indices related with undesirable output have a larger role in deciding bench marking airline. 2. For most of the 29 airlines, CNG2020 strategy has little influence on their efficiency. (C) 2017 Elsevier Ltd. All rights reserved.
