Environmental regulations are considered a prerequisite for environmental performance. However, very limited studies have explored the asymmetric relationship between clean energy consumption, environmental regulation, and CO emissions. This study scrutinizes the asymmetry phenomenon in environmental regulation-clean energy consumption and environmental quality nexus in China by using the time series nonlinear ARDL approach by covering the period 1993-2019. The result reveals that the impact of environmental regulation on clean energy consumption and CO emissions is asymmetric. A positive change in environmental regulation has a positive effect on clean energy consumption but a negative impact on CO emissions in the long run. While a negative change in environmental regulation has insignificant effects on clean energy consumption and CO emissions in the long run. The study suggests that China should need to revisit environmental regulation policies that could help in improving environmental quality.
环境法规被认为是环境绩效的前提。然而，很少有研究探讨清洁能源消费、环境规制与 CO 排放之间的这种非对称关系。本研究通过使用时间序列非线性 ARDL 方法，在 1993 年至 2019 年期间，研究了中国环境规制-清洁能源消费和环境质量关系中的非对称现象。结果表明，环境规制对清洁能源消费和 CO 排放的影响是非对称的。从长期来看，环境规制的正向变化对清洁能源消费有积极影响，但对 CO 排放有负面影响。而从长期来看，环境规制的负向变化对清洁能源消费和 CO 排放没有显著影响。本研究建议，中国需要重新审视环境规制政策，这有助于改善环境质量。
