Abstract

Understanding the relationship between the environmental quality and economic growth has increasingly attracted the attention of economists. The literature on this relationship focuses on testing the Environmental Kuznets Curve (EKC) hypothesis. The aim of this study is to examine the relationship between income and the CO2 emission by using time series analysis for Turkey. The validity of the EKC is investigated by the Johansen cointegration test using the data for the time period 1960-2011. The results of our time series analysis suggest a cointegrating relationship between income and the CO2 emission. The results also indicate an N-shaped relationship between these variables, which in turn imply that the EKC hypothesis is not supported by this data set.

Keywords: CO2 Emissions, Cointegration, Economic Growth, Environmental Kuznets Curve, Income

Çevresel Kuznets Eğrisi’nin Ekonometrik Bir Analizi: Türkiye Örneği

Öz

Çevresel kalite ve ekonomik büyüme arasındaki ilişkinin kavranması iktisatçıların artan biçimde ilgisini çekmektedir. Söz konusu ilişki üzerine literatür Çevresel Kuznets Eğrisi (ÇKE) hipotezinin test edilmesine odaklanmaktadır. Bu çalışmanın amacı, gelir ve CO2 emisyonu arasındaki ilişkiyi zaman serisi analizi kullanarak Türkiye için test etmektir. ÇKE’nin geçerliliği 1960-2011 dönemine ait veriler kullanılarak Johansen Eşbütünleşme testi ile araştırılmaktadır. Zaman serisi analizimizin sonuçları gelir ve CO2 emisyonu arasında eşbütünleşik bir ilişkinin olduğunu ortaya koymaktadır. Sonuçlar ayrıca bu değişkenler arasında N-biçiminde bir ilişki olduğunu göstermektedir ki, bu da söz konusu veri setinin ÇKE hipotezini desteklemediğine işaret etmektedir.

Anahtar Kelimeler: CO2 Emisyonları, Ekonomik Büyüme, Eşbütünleşme, Gelir, Çevresel Kuznets Eğrisi
