Özet:

In this study, data coverage analysis VZA and Malmquist Total Factor Efficiency Indices used the activities of the 42 airports associated with DHMİ to the General Directorate of the State Airport Administration in Turkey between 2014-2018 years. As of 2018, there are 56 airports open to civil air transport in Turkey. However, according to the structure of the Data Surfing Analysis and Malmquist Total Factor Efficiency Index methods, during the analysis period, airports with uninterrupted data have been selected to provide healthy results for the analysis. Therefore, the work included 42 airports with uninterrupted data belonging to the General Directorate of the State Airport Business in Turkey. As the first stage of the study, through the Data Coverage Analysis, the activity values of the airports have been identified in a five-year period, including in 2018, starting in 2014. Airports that are effective and not captured the value of activity are identified. Last year, the airports that could be referred to in effect by the activity values were identified and the reference intensity values were identified and the results were made a table. Then, as a second phase, with the help of the Malmquist Total Factor Efficiency Indices, the developments they have shown in the values of Total Factor Efficiency over the course of the analysis period of years have been revealed. Data coverage analysis is set in entry-oriented and according to scale under the fixed return assumption. In the analysis, five entrance values were determined, including the number of employees, operating costs, terminal area m2, the number of tracks and the number of aprons. As the outcome values, four values were included in the analysis, such as passenger traffic, business income, air traffic and cargo traffic. The results of the analysis are evaluated and aimed at contributing to the work aimed at improving the performance of its airports in Turkey.

Özet:

In this study, efficiencies of 42 airports between the years 2014 and 2018 which are affiliated to the General Directorate of State Airports Authority in Turkey were examined by Using Data Envelopment Analysis DEA and Malmquist Total Factor Productivity Indices. As of 2018, Turkey has 56 airports open to civil air transport. However, due to the nature of Data Envelopment Analysis and Malmquist Total Factor Productivity Indices methods, airports with uninterrupted data have been selected over the years for the analysis to provide a sound result. Therefore, 42 airports with continuous data which are affiliated to the General Directorate of State Airports Authority have been included in the research. As a first step in the study, the efficiency values of the airports have been determined by means of Data Envelopment Analysis for a period of 5 years including 2018 starting from 2014. The airports that are efficient and not efficient are identified. According to the efficiency values of the last year, the airports which can be referenced for inefficient airports to be efficient were determined and by determining reference density values the results were tabulated. Then, as the second stage, with the help of Malmquist Total Factor Productivity Indices, the improvements in total factor productivity values of the airports during the analysis period have been revealed. Data envelopment analysis has been arranged under the assumption of input-oriented and constant returns to scale. In the analysis, five input values were determined: number of employees, operating expenses, terminal area m2 , number of runways and number of aprons. As output values, four values as passenger traffic, operating income, aircraft traffic and freight traffic are included in the analysis. Thorough evaluating of the results obtained from the analysis, it is aimed to contribute to the efforts to improve the performance of airports in Turkey
