Abstract

This research examines the impacts of urban population growth on per capita $CO_2$ emissions with particular focus on the interaction effect between urbanization and income levels. Employing the Panel Fixed Effects model together with the Pooled LS and Panel GLS models, the research reported here analyzes the relevant data on 84 countries. The statistical results show a nonlinear(an inverted-U) relationship between urbanization and per capita $CO_2$ emissions; that is, while the urban agglomeration leads to increases in per capita $CO_2$ emissions for low income countries, this adverse impact does not hold true for high income countries. The research findings can contribute to addressing broad issues of urban compactness and patterns of energy consumption that should be considered by those concerned about the sustainable urban development.

본 연구는 도시화가 1인당 탄소 배출에 미치는 영향을 도시화와 소득 수준 간의 교호 작용을 중심으로 분석하였다. 이를 위해 84개 국가에 대한 패널 자료를 고정효과 모형을 통해 회귀분석하고 동시에 Pooled LS 모형 및 패널 GLS 모형과도 비교하였다. 그 결과 1인당 탄소배출과 도시화는 비선형적 관계를 이루는 것으로 나타났다. 즉 저소득 국가에서 도시로의 인구 집중이 1인당 탄소 배출을 증가시키는 반면, 고소득 국가에서는 오히려 반대의 효과가 나타났다. 이러한 본 연구의 결과는 도시의 압축성(compactness)과 에너지 소비 패턴에 대한 논의로 확장할 수 있으며, 이를 통해 지속가능한 도시개발을 위한 연구와 정책 개발의 토대를 제공할 수 있다.
