This study uses absolute market concentration (CRN) and relative market concentration (HHI) in three different categories for the first time to quantitatively analyse the degree of competition and concentration of Turkish civil aviation transport between 2012 and 2022. The production efficiency is calculated by the DEA method. Finally, these two factors are empirically tested by using a cointegration test. The relationship between production efficiency and market concentration in the Turkish civil aviation industry is unstable in the long run during this period. To accelerate the development of the industry and transform its efficiency into a stable structure, it could be beneficial to deepen the studies on international markets.
