Abstract

The present study investigates the relationship between economic growth, globalization, population density, energy consumption, trade openness, and carbon dioxide (CO2) emissions under the Environmental Kuznets Curve (EKC) framework for selected highly cross-correlated countries (Middle East and North Africa-MENA) from 1994 to 2014. The control variables are used based on previous empirical research. Cross-sectional dependence tests, cointegration analysis, panel data estimators (models with Driskoll-Kraay standard errors, FGLS, FMOLS, and DOLS), and Granger causality are performed. Empirical findings validate the EKC hypothesis and suggest that energy use significantly and negatively contributes to environmental quality. Moreover, globalization increases environmental degradation, whereas trade openness and population density may reduce carbon dioxide emissions within MENA economies. Policy implications towards economic growth decoupled from fossil fuels could benefit environmental upgrades and sustainability.

二氧化碳排放框架下EKC的调查:来自交叉相关国家的经验证据
本研究在环境库兹涅茨曲线(EKC)框架下,调查了1994年至2014年选定的高度相关国家(中东和北非和中东和北非)的经济增长、全球化、人口密度、能源消耗、贸易开放和二氧化碳排放之间的关系。控制变量的使用基于先前的实证研究。进行了横断面相关性检验、协整分析、面板数据估计量(具有Driskoll-Kraay标准误差、FGLS、FMOLS和DOLS的模型)和Granger因果关系。实证结果验证了EKC假说,并表明能源使用对环境质量有显著的负面影响。此外,全球化加剧了环境退化,而贸易开放和人口密度可能会减少中东和北非经济体的二氧化碳排放。与化石燃料脱钩的经济增长政策影响可能有利于环境升级和可持续性。
