THE IMPACT OF ENERGY CONSUMPTION ON ENVIRONMENTAL POLLUTION: A PANEL DATA ANALYSIS

Öz

Using the panel data, this study was conducted to analyse the impact of energy consumption on carbon dioxide emissions for low-income, middle-income and high-income countries from 1971 to 2011. The results indicate that there is a long-run equilibrium relationship between variables for middle-income and high-income countries. Additionally, causality running from energy consumption to carbon dioxide emissions was observed for these countries. Parameter estimations show that the energy elasticity of carbon dioxide emissions in middle-income countires is higher than that of high-income countries. These empirical findings present some important policy implications.

ENERJİ TÜKETİMİNİN ÇEVRE KİRLİLİĞİ ÜZERİNDEKİ ETKİSİ: BİR PANEL VERİ ANALİZİ

Öz

Bu çalışma, 1971-2011 döneminde panel veri metodolojisini kullanarak düşük, orta ve yüksek gelirli ülkeler grubu için enerji tüketiminin karbon dioksit salınımı üzerindeki etkisini analiz etme amacını taşır. Sonuçlar, orta ve yüksek gelirli ülkeler grubu için değişkenler arasında bir uzun dönem denge ilişkisinin varlığını göstermektedir. Ayrıca, bu iki ülke grubu için enerji tüketiminden karbon dioksit salınımına doğru işleyen bir nedensellik tespit edilmiştir. Parametre tahminleri, karbon dioksit salınımının enerji elastikiyetinin orta gelirli ülke grubunda yüksek gelirli ülke grubuna göre daha yüksek olduğunu kanıtlamaktadır. Söz konusu ampirik bulgular, önemli politika çıkarımları sunmaktadır.
