Evaluating the strategic role of stringent environmental policies and innovative technologies in China’s green energy transitions

China's massive reliance on fossil energy consumption is considered as the major hindrance in achieving carbon neutrality and environmental protection goals. However, China is committed to reduce the proportion of non-renewable energy for achieving the dual goals of carbon peaking and carbon neutrality by 2030 and 2060, respectively. To meet these aspiring goals, China mainly relies on technological innovations and climate protections policies implementations for transforming fossil energy to renewable energy consumption. The present research is intended to assess the impact of environmental policy stringency (EPS) and technological innovations in China's green energy transitions. Based on the nature of research data, the quantile regression model was applied to precisely explore the drivers of green energy transitions in China from 1990 to 2020 in various quantiles. The finding indices that technology innovation, EPS, and renewable energy index had accelerated the green energy transitions, while, the non-renewable energy consumption exhibited a negative impact. The results also revealed that impact of the solar and hydro installation capacity was significantly increase in the second quantile. The empirical analysis of this study informs several policy directions aimed at facilitating China's green energy transitions and decarbonizing goals.
