Çevresel Kuznets eğrisi hipotezinin geçerliliği ve yeşil lojistik: Türkiye örneği

Öz:
Bu çalışma çevresel Kuznets eğrisi (ÇKE) hipotezi kapsamında 1995-2016 döneminde Türkiye’de lojistik, ekonomik büyüme ve karbondioksit (CO2) salımı arasındaki ilişkiyianaliz etmektedir. Bu çalışmada Fourier otoregresif gecikmesi dağıtılmış (ADL) eşbütünleşme testi, tam değiştirilmiş en küçük kareler (FMOLS), kanonik eşbütünleşme regresyonu(CCR) uzun dönem tahmincileri ve Toda-Yamamoto (TY) ve Fourier TY nedensellik yöntemleri kullanılmıştır. Fourier ADL eşbütünleşme yöntemine göre seriler arasında uzun dönemli bir ilişki olduğu belirlenmiştir. Uzun dönem tahmincilerinden elde edilen sonuçlaragöre Türkiye’de ÇKE hipotezinin geçerli olduğu tespit edilmiştir. Bununla birlikte, dönümnoktaları ilgili periyodun dışındadır. Bu nedenle Türkiye, CO2 salımını azaltmak için gerekli ekonomik büyüme düzeyine henüz ulaşmamış durumdadır. Bunun yanında lojistik uzundönemde kişi başına düşen CO2 salımını pozitif yönde etkilemektedir. Ampirik sonuçlaragöre ulaşım altyapısındaki gelişim CO2 salımına neden olmaktadır. Son olarak, Fourier TYyöntemine göre ekonomik büyüme-CO2 salımı ve Lojistik-CO2 salımı arasında çift yönlübir nedensellik ilişkisi bulunmaktadır. Yeşil lojistik faaliyetlerinin gerçekleştirilmesi ve CO2salımının azaltılması için Türkiye’de uygun yapısal reformların gerçekleştirilmesi gerekmektedir.

The validity of environmental Kuznets curve hypothesis and green logistic: The case of Turkey

Öz:
This study analysed the relationship between logistics, economic growth, and carbon dioxide (CO2 ) emissions within the framework of the environmental Kuznets curve (EKC) hypothesis from 1995 to 2016 in Turkey. The study uses a Fourier autoregressive distributed lag (ADL) cointegration test, fully modified ordinary least squares (FMOLS), canonical cointegration regression (CCR) long-term estimators, and Toda-Yamamoto (TY) and Fourier TY causality methods. According to Fourier ADL cointegration method, there is a long-run relationship between the series. The results of long run estimators demonstrate that the EKC hypothesis is valid for Turkey. However, the turning points lie outside the sample period. Therefore, Turkey has not yet reached the level of economic growth necessary to reduce CO2 emissions. In addition, an increase in logistic has a positive effect on per capita CO2 emissions in the long term. The empirical results reveal that an improvement in the transportation infrastructure conditions causes CO2 emissions. Finally, according to the Fourier TY method, there is a two-way causality relationship between economic growthCO2 emissions, and logistics-CO2 emissions. To realize green logistic activities and reduce CO2 emissions, appropriate structural reforms are required in Turkey.
