该研究考察了1990年至2018年期间西非国家碳排放、可再生能源消费和经济增长之间的关系。为了能够发现可靠和有效的结果，本研究采用了更稳健的面板估计方法。从异质性和横截面依赖性测试，该研究的面板是异质性和横截面依赖性。同时，所有序列在水平上都是非平稳的，但在第一次差分后获得了平稳性。此外，Fisher检验和Westerlund和埃杰顿bootstrap检验发现变量在长期内协整。利用CCEMG和DCCEMG两种估计方法探讨了中国经济增长的长期均衡关系，结果表明，在两种估计方法下，CO2排放量和可再生能源消费量对中国经济增长的影响均不显著。然而，在分小组中，结果略有不同。此外，从整个样本中，控制变量城市化（URB）和人口增长（POP）对GDP的估计没有实质性的影响。然而，各小组的结果却不一样。最后，采用Dumitrescue-Hurlin检验来检验系列中的因果关系，结果在各个面板中存在差异。进一步讨论了政策建议。
This study examined the nexus between carbon emissions, renewable energy consumption, and the economic growth of West African countries for the period 1990 to 2018. To be able to uncover reliable and valid findings, more robust panel estimation methods were employed for the study. From the heterogeneity and cross-sectional dependence tests, the study’s panels were heterogeneous and cross-sectionally dependent. Also, all the series were non-stationary at levels, but gained stationarity after first difference. Further, the Fisher test and the Westerlund and Edgerton bootstrap test found the variables to be cointegrated in the long run. The CCEMG and the DCCEMG estimators were used to explore the long-run equilibrium relationship amid the series, and from the results of the whole sample, CO2emissions and renewable energy consumption (REC) had no vital influence on economic growth (GDP) in both estimators. However, the results were a bit different in the sub-panels. Also from the whole sample, control variables urbanization (URB) and population growth (POP) had no material effect on GDP in both estimators. The results were, however, dissimilar in the sub-panels. Finally, the Dumitrescu-Hurlin test was employed to examine the causalities amid the series, and the results were diverse in the various panels. Policy recommendations are further discussed.
