Türkiye’de CO2 Emisyonu ve Sağlık Harcamaları: Ekonomik Büyüme, Yenilenebilir Enerji Tüketimi ve Kentleşme Üzerine Ampirik Kanıtlar

Abstract

Bu çalışma, Türkiye’ de sağlık harcamaları, yenilenebilir enerji tüketimi ve ekonomik büyüme ile çevre kirliliği arasındaki ilişkiyi incelemektedir. Bu kapsamda kişi başına düşen gayri safi yurtiçi hasıla, kişi başına düşen sağlık harcamaları, yenilenebilir enerji tüketimi ve kentsel nüfus artışı ile kişi başına düşen CO2 emisyonu değişkenleri kullanılarak uzun ve kısa dönemli etkileri otoregresif dağıtılmış gecikme (ARDL) yöntemi ile analiz edilmiştir. 1990-2021 dönemi için yıllık zaman serisi verileri kullanılmıştır. Analiz sonucu değişkenler arasında eş bütünleşme ilişkisinin mevcut olduğunu göstermektedir. Uzun dönemde ekonomik büyüme ile CO2 emisyonu arasında pozitif yönlü, yenilenebilir enerji tüketimi, sağlık harcamaları ve kentleşme ile CO2 emisyonu arasında ise negatif yönlü bir ilişki ortaya çıkmaktadır. Kısa dönemde sadece ekonomik büyüme ile yenilenebilir enerji tüketiminin CO2 emisyonu ile ilişkili olduğu belirlenmiştir. Bu sonuçlara göre Türkiye’ de çevre kirliliğini önlemek için çevresel sürdürülebilirliği dikkate alan ekonomik büyüme ve sağlık harcamaları politikalarının ve aynı zamanda yenilenebilir enerji tüketimini artıran politikaların teşvik edilmesi gerekmektedir.

CO2 Emissions and Health Expenditures in Türkiye: Empirical Evidence on Economic Growth, Renewable Energy Consumption, and Urbanization

Abstract

This study examines the relationship between healthcare expenditures, renewable energy consumption, economic growth, and environmental pollution in Türkiye. In this context, the long- and short-term effects of per capita gross domestic product, per capita healthcare expenditures, renewable energy consumption, urban population growth, and per capita CO2 emissions were analyzed using the autoregressive distributed lag (ARDL) method. Annual time series data were used for the period 1990-2021. The analysis demonstrates a cointegration relationship between the variables. In the long term, a positive relationship was identified between economic growth and CO2 emissions, while a negative relationship emerges between renewable energy consumption, healthcare expenditures, urbanization, and CO2 emissions. In the short term, only economic growth and renewable energy consumption are associated with CO2 emissions. According to these results, to prevent environmental pollution in Türkiye, economic growth and healthcare spending policies that take environmental sustainability into account, as well as policies that increase renewable energy consumption, should be encouraged.
