Renewable energy innovations are essential for mitigating greenhouse gas emissions and addressing climate change, guaranteeing a more pristine and healthful environment. Moreover, these advancements stimulate economic expansion by establishing novel sectors and employment prospects while improving energy reliability and ecological viability. For the first time, the current study explores how supply chain disruption and digitalization impact renewable energy innovations. Besides, the study also considered the role of control variables, including human capital, globalization, economic growth, and democracy. The study used moment quantile regression as an estimator focused on the G7 economies, with data from 1990 to 2020. The study findings show supply chain disruption's insignificant and adverse effect on renewable energy innovations. Furthermore, digitalization promotes renewable energy innovations across all quantiles. Besides, this study also found the effectiveness of economic growth in promoting renewable energy innovations across all quantiles. On the contrary, globalization consistently hampers renewable energy innovations across all quantiles, while democracy is seen as an effective tool in increasing renewable energy innovations. The study formulates policies based on these findings.

供应链中断和数字化对可再生能源创新的作用：来自 G7 国家的证据


可再生能源创新对于减少温室气体排放和应对气候变化至关重要，从而保证更原始和健康的环境。此外，这些进步通过建立新的行业和就业前景来刺激经济扩张，同时提高能源可靠性和生态可行性。目前的研究首次探讨了供应链中断和数字化如何影响可再生能源创新。此外，该研究还考虑了控制变量的作用，包括人力资本、全球化、经济增长和民主。该研究使用时刻分位数回归作为估计器，重点关注 G7 经济体，数据从 1990 年到 2020 年。研究结果表明，供应链中断对可再生能源创新的影响微不足道且不利。此外，数字化促进了所有分位数的可再生能源创新。此外，这项研究还发现经济增长在促进所有分位数的可再生能源创新方面的有效性。相反，全球化始终阻碍着所有分位数的可再生能源创新，而民主被视为增加可再生能源创新的有效工具。该研究根据这些发现制定政策。
