Several efforts have been made to explore the income inequality influence on environmental degradation, but the query regarding the nexus of income inequality and renewable energy consumption (REC) is still unanswered. This vacuum in existing literature has raised the need to inspect the relationship between income inequality and REC. Thus, this study purposes to investigate the asymmetric effect of income inequality on REC for emerging Asian economies over the period 1990-2019 by adopting the nonlinear autoregressive distributed lag (NARDL) approach. The panel-wise long-run results infer that positive shock in income inequality exerts a significant negative effect on REC, while negative shock in income inequality has an insignificant effect on REC. Likewise, economy-wise long-run findings reveal that a positive shock in income inequality brings a negative and statistically significant influence on REC in the case of China, India, and Iran, while a negative shock in income inequality brings a positive influence on REC only in case of Russia.
已经有多项研究探讨了收入不平等对环境恶化的影响，但关于收入不平等与可再生能源消费（REC）之间关系的问题仍未得到解答。现有文献中的这一空白使得有必要检验收入不平等与 REC 之间的关系。因此，本研究旨在通过采用非线性自回归分布滞后（NARDL）方法，考察 1990-2019 年期间新兴亚洲经济体收入不平等对 REC 的不对称影响。面板长期结果推断，收入不平等的正向冲击对 REC 产生显著的负向影响，而收入不平等的负向冲击对 REC 没有影响。同样，从经济角度来看，长期结果表明，在中国、印度和伊朗，收入不平等的正向冲击对 REC 产生负面影响且在统计上显著，而收入不平等的负向冲击仅对俄罗斯的 REC 产生正向影响。
