摘要

汇款与二氧化碳（CO2）排放之间的关系仍然是文献中争论的热点，大多数研究得出的结论不一。本研究采用修正的环境库兹涅茨曲线（Environmental Kuznets Curve）框架，调查了汇款对南部非洲关税同盟（SACU）地区主要汇款接收国二氧化碳排放的非线性影响，重点研究汇款可能对二氧化碳排放产生的影响，试图调和这些差异。横截面自回归分布滞后（CS-ADRL）方法适用于 1990 年至 2020 年期间这些汇款最多的国家，这是对这些国家进行的一项开创性调查。研究结果表明，汇款及其二次项的估计系数在统计意义上都是显著的，汇款的系数为正，二次项的系数为负。这一模式证实了修正的 EKC 假设的存在，即随着汇款的增加，二氧化碳水平呈现出明确的倒 U 型轨迹。

Remittance and carbon dioxide emissions in the Southern African Customs Union region: Is there a modified environmental Kuznets curve?

The remittance-carbon dioxide (

C O_{2}

) emissions nexus remains a hotly debated topic in the literature, with the majority of studies offering mixed conclusions. This study attempts to reconcile these disparities by investigating the nonlinear effect of remittances on the

C O_{2}

emissions in top-remittance receiving countries in Southern African Customs Union (SACU) region, using the modified Environmental Kuznets Curve framework which focuses on the effect that remittances might have on

C O_{2}

emissions. The Cross-Sectional Autoregressive Distributed Lag (CS-ADRL) approach is applied to these top-remittance receiving countries from 1990 to 2020, representing a pioneering investigation for these countries. The finding of this study reveal that both the estimated coefficient of remittances and its quadratic term are statistically significant, with remittances displaying a positive coefficient and the quadratic term exhibiting a negative coefficient. This pattern confirms the presence of a modified EKC hypothesis, meaning as remittances increases,

C O_{2}

levels displays an unambiguous inverted U-shaped trajectory.
