A window dea based efficiency evaluation of the public airports in Turkey: 2014-2019 case
Abstract
Aviation is strategically important because of its enormous contribution to the economy, as well as being the field of application and production of new technologies. The efficiency of airports comes to the fore in efficiency researches in aviation. However, efficiency analyzes with Data Envelopment Analysis (DEA) using single-year data may not be sufficient to determine the trend. Therefore, output-oriented Window-DEA (W-DEA) using multi periods was performed in this study. Moreover, W-DEA provides information about the increases and decreases in the efficiency trends of airports. The research was carried out with the data of 42 Turkish airports for the period 2014-2019. The findings show that two airports in Istanbul as well as Adana, Van and Antalya airports have high efficiency. With this study, measuring the performance of Turkish airports with W-DEA has been brought to the literature. This study will shed light on the feasibility studies of new investments as well as the sustainability and competitiveness studies.
