Abstract

Understanding the efficiency dynamics of green innovations is essential for advancing sustainable economic systems. This study evaluates the efficiency of forty-two countries in producing and utilizing green innovations for clean energy production and in achieving sustainable development goals from 2000 to 2020. Employing a network bias-corrected data envelopment analysis (DEA) and Malmquist productivity analysis, this study explores the adoption of green technology and its effects on economic and environmental efficiency. Findings reveal limited progress in clean energy efficiency across most countries, indicating suboptimal use of green innovations for the goals of affordable and clean energy and climate action). The results show that the efficiency pattern of green innovations follows a U-shaped curve, with initial inefficiencies followed by long-term gains. South American nations and the European Union demonstrate strong performance in integrating green technologies. However, green innovations alone appear insufficient; supportive policies, such as green taxes on emissions and renewable energy initiatives, are crucial for enhancing impact and achieving environmental sustainability.

评估绿色创新和可再生能源在实现可持续发展目标方面的效率

了解绿色创新的效率动态对于推进可持续经济体系至关重要。本研究评估了 42 个国家从 2000 年到 2020 年在生产和利用绿色创新技术生产清洁能源以及实现可持续发展目标方面的效率。本研究采用网络偏差校正数据包络分析法（DEA）和 Malmquist 生产率分析法，探讨了绿色技术的采用及其对经济和环境效率的影响。研究结果表明，大多数国家在清洁能源效率方面取得的进展有限，这表明在实现负担得起的清洁能源和气候行动的目标方面，对绿色创新的利用还不够理想。）研究结果表明，绿色创新的效率模式呈 U 型曲线，最初效率低下，随后长期收益。南美国家和欧盟在整合绿色技术方面表现突出。然而，仅有绿色创新似乎还不够；支持性政策，如绿色排放税和可再生能源倡议，对于增强影响和实现环境可持续性至关重要。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
