Abstract

This study analyzed the determinants of carbon dioxide emissions through the expanded STIRPAT model using panel data from 16 metropolitan cities and provinces in Korea from 2000 to 2019. After testing cross-sectional dependence and coefficient heterogeneity of panel data, we performed analysis using MG, CCEMG, and AMG estimation methods reflected these characteristics. The results of analysis using the AMG estimation method are as follows. The coefficients of income, population, and energy intensity were statistically significant with a positive sign, but urbanization was statistically insignificant. Reduction of carbon dioxide emissions in Korea can be achieved through an increase in energy efficiency and sustainable economic growth. It is necessary to establish a policy that can contribute to sustainable economic growth by inducing productivity improvement through technology innovation reducing carbon dioxide emissions in the long-term as well as building a low-carbon society through active development of carbon dioxide reduction technology.

본 연구는 2000년부터 2019년까지 우리나라 16개 광역시·도의 패널자료를 활용하여 확장된 STIRPAT 모형을 통해 이산화탄소 배출량 결정요인을 분석하였다. 패널 데이터의 횡단면 의존성과 계수 이질성을 검정한 후, 이들 특성을 반영한 MG, CCEMG, AMG 추정법을 통해 분석하였다. AMG 추정법을 통해 분석한 결과를 살펴보면, 소득, 인구, 에너지 집약도의 계수가 양(+)의 부호로 통계적으로 유의하게 나타났으나, 도시화는 통계적으로 유의하지 않는 것으로 나타났다. 우리나라 이산화탄소 배출량의 감소는 에너지 효율의 증가와 지속가능한 경제성장을 통해 이루어질 수 있다. 따라서 이산화탄소 감축기술의 적극적인 개발로 저탄소 사회를 구축하고, 이와 함께 기술혁신을 통해 장기적으로 생산성 향상을 유발하여 지속가능한 경제성장에 기여할 수 있는 정책수립이 필요하다.
