Bu çalışmanın amacı, iklim değişikliğinin ihracat ürün çeşitlendirmesi üzerinde etkisini araştırmaktır. Bu amaç doğrultusunda, Ekonomik Kalkınma ve İş Birliği Örgütü (OECD) üyesi 37 ülkeye ait veriler, 1995-2022 dönemi için Kesirli Logit Model ile Moment Kantil Regresyon (MMQR) kullanılarak analiz edilmiştir. Analiz sonuçları, yağış miktarı ve ortalama sıcaklıktaki artışların ihracat ürün çeşitlendirmesinden ziyade ihracat ürün yoğunlaşmasına yol açtığını göstermektedir. Diğer yandan ekolojik ayak izindeki artış ise ihracat ürün yoğunlaşmasını azaltmaktadır. Elde edilen bu sonuçlara göre OECD ülkelerinde iklim değişikliği ihracat ürün çeşitlendirmesini olumsuz etkilemekte, bu durumda ülkeler ihracat kompozisyonlarında iklim değişikliğinin etkisini göz önünde bulundurması gerekmektedir.

The Effects of Climate Change on Export Product Diversification: Evidence from OECD Countries

Öz

The aim of this study is to investigate the impact of climate change on export product diversification. For this purpose, data from 37 Organization for Economic Cooperation and Development (OECD) member countries are analyzed using the Fractional Logit Model and Moment Quantile Regression (MMQR) for the period 1995-2022. The results of the analysis show that increases in rainfall and average temperature lead to export product concentration rather than export product diversification. On the other hand, an increase in ecological footprint reduces export product concentration. According to these results, climate change has a negative impact on export product diversification in OECD countries and countries should consider the impact of climate change in their export composition.
