EXAMINATION OF THE AVIATION PERFORMANCE OF G20 COUNTRIES

In this study, the performance of G20 countries in the aviation sector in 2023 is analyzed comparatively. The aim is to reveal the extent to which countries are able to maximize their sectoral outputs with the available resources. Inputs (number of commercial airports, aviation investment, total number of employees) and outputs (annual passenger traffic, cargo volume, economic contribution of aviation) are considered. Turkey, USA, Germany, UK, China, France, South Korea, Indonesia, Argentina, Italy and South Africa were found to be fully efficient. In contrast, Australia, Brazil, India, Japan, Japan, Canada, Mexico, Mexico and Saudi Arabia were below the efficiency threshold. In particular, South Korea and the USA stand out as the most exemplary reference units for many countries. The findings provide policy recommendations for more efficient use of resources in the aviation sector.
