本文实证研究了环境库兹涅茨曲线（EKC）的情况下，11个经合组织国家的二氧化碳排放量，考虑到核能在电力生产中的作用。估计方法采用协整的自回归分布滞后方法。我们的研究结果表明，能源消费对大多数国家的二氧化碳排放量有积极的影响。然而，贸易的影响在统计上并不显著。研究结果为核电在减少二氧化碳排放方面的作用提供了证据，但仅在一些国家。此外，尽管芬兰、日本、韩国和西班牙的估计长期收入系数及其平方满足EKC假设，但只有芬兰的EKC转折点在研究的样本期内，为支持EKC假设提供了较差的证据。
This article empirically investigates the Environmental Kuznets Curve (EKC) for CO2 emissions in the cases of 11 OECD countries by taking into account the role of nuclear energy in electricity production. The autoregressive distributed lag approach to cointegration is employed as the estimation method. Our results indicate that energy consumption has a positive impact on CO2 emissions in most countries in the study. However, the impact of trade is not statistically significant. The results provide evidence for the role of nuclear power in reducing CO2 emissions only in some countries. Additionally, although the estimated long-run coefficients of income and its square satisfy the EKC hypothesis in Finland, Japan, Korea and Spain, only Finland's EKC turning point is inside the sample period of the study, providing poor evidence in support of the EKC hypothesis.
