The purpose of this article is to empirically find the Environmental Kuznets Curve (EKC) relationship between income and carbon dioxide (CO) emissions and to analyze the influence of population aging on such emissions. We utilize Korean regional panel data of 16 provinces during the period from 1998 to 2016. To account for the nonstationary time series in the panel, we employ a fully modified ordinary least squares (FMOLS) and estimate long-run elasticity. From the empirical results, we can find the nonlinear relationship between income and CO emissions. Additionally, we verify the fact that population aging reduces CO emissions. A 1% increase in the proportion of the elderly results in a 0.4% decrease in CO emissions. On the other hand, the younger population increases CO emissions. These results were in line with those of additional analysis on residential and transportation CO emissions, for the robustness check.
本文旨在通过实证研究，发现收入和二氧化碳（CO）排放之间的环境库兹涅茨曲线（EKC）关系，并分析人口老龄化对这些排放的影响。我们利用了韩国 1998 年至 2016 年期间 16 个省份的区域面板数据。为了考虑面板中时间序列的非平稳性，我们采用全修正最小二乘法（FMOLS）进行估计，并计算长期弹性。从实证结果来看，我们可以发现收入和 CO 排放之间存在非线性关系。此外，我们验证了人口老龄化减少 CO 排放的事实。老年人口比例每增加 1%，CO 排放量就会减少 0.4%。另一方面，年轻人口会增加 CO 排放。这些结果与对住宅和交通 CO 排放的额外分析结果一致，具有稳健性。
