Enhancing energy efficiency is very effective in supporting environmental sustainability. Financial inclusion, human capital, and technological innovation are newly cited as dominant factors for environmental sustainability in emerging economies. Against this background, this study investigated how financial inclusion and technological innovation affected energy efficiency in E7 countries from 2004 to 2021. The study identifies the diverse effect of variables at different quantiles through a novel Moments Quantile Regression (MM-QR) method to explore the heterogeneous interconnection among the variables The MMQR outcomes suggest financial inclusion positively affects energy efficiency across all quantiles. Besides, the findings show that human capital positively affects energy efficiency in E7 countries at lower, medium, and higher quantiles. At the same time, estimated outcomes suggest that technological innovation promotes energy efficiency only at lower quantiles. This study recommends appropriate policies for decision-makers in E7 economies based on the study outcomes regarding adequately channelling human capital, financial resources, and technological innovation to promote energy efficiency and achieve sustainable development goals.

技术创新、人力资本和能源效率之间的关系：来自 E7 国家的证据


提高能源效率对于支持环境可持续性非常有效。金融包容性、人力资本和技术创新最近被认为是新兴经济体环境可持续性的主导因素。在此背景下，本研究调查了2004年至2021年金融普惠和技术创新如何影响E7国家的能源效率。该研究通过一种新颖的矩分位数回归（MM-QR）方法识别了不同分位数变量的不同影响，以探讨变量之间的异质互连 MMQR 结果表明，金融包容性对所有分位数的能源效率产生积极影响。此外，研究结果表明，人力资本对 E7 国家的能源效率的低、中、高分位数产生积极影响。与此同时，估计结果表明，技术创新只能在较低的分位数上提高能源效率。本研究根据有关充分引导人力资本、财政资源和技术创新以提高能源效率和实现可持续发展目标的研究结果，为E7经济体的决策者提出适当的政策建议。
