G20 ÜLKELERİNİN HAVACILIK PERFORMANSININ İNCELENMESİ

Öz

Bu çalışmada, G20 ülkelerinin havacılık sektöründeki 2023 yılı performansı karşılaştırmalı olarak analiz edilmiştir. Amaç, ülkelerin mevcut kaynaklarla sektörel çıktılarını ne ölçüde maksimize edebildiklerini ortaya koymaktır. Girdiler (ticari havalimanı sayısı, havacılık yatırımı, toplam çalışan sayısı) ve çıktılar (yıllık yolcu trafiği, kargo hacmi, havacılığın ekonomik katkısı) dikkate alınmıştır. Türkiye, ABD, Almanya, İngiltere, Çin, Fransa, Güney Kore, Endonezya, Arjantin, İtalya ve Güney Afrika'nın tam verimli olduğu görülmüştür. Buna karşılık, Avustralya, Brezilya, Hindistan, Japonya, Kanada, Meksika, Meksika ve Suudi Arabistan verimlilik eşiğinin altında kalmıştır. Özellikle Güney Kore ve ABD, birçok ülke için en örnek referans birimleri olarak öne çıkmaktadır. Bulgular, havacılık sektöründe kaynakların daha verimli kullanılması için politika önerileri sunmaktadır.

EXAMINATION OF THE AVIATION PERFORMANCE OF G20 COUNTRIES

Öz

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.
