저가항공사의 운영효율성과 판매효율성 분석

초록

In this study, we suggest an efficiency evaluation model for low-cost carriers (LCC). Considering data of five LCCs in Korea for the period 2012-2014, the proposed model is utilized and examined. A two-stage model was proposed to complement the limitations of existing studies, based on data envelopment analysis (DEA), which is the most popular methodology for deriving efficiency in the airline industry. The proposed model structure can be analyzed to identify the causes of inefficiency by dividing total efficiency into operational and sales efficiency. The sequential calculation scheme is employed by calculating operational efficiency first, and then deriving sales efficiency accordingly, while restricting operational efficiency. This property reflects LCCs’ strategy, which generally focuses on operational efficiency. To ensure that the methodology is realistic, assumptions on the intermediates in the two-stage DEA model were relaxed. In addition, comparison with the results obtained from a previous study is presented to aid understanding of the proposed model.
