Advancement in renewables is one of the most effective techniques for sustained long-term development, and nations across the globe are making efforts to change their economic and industrial structures in a bid to boost green growth. With the advent of the Fourth Industrial Revolution (4IR), the availability, access, and use of green technologies including renewable energy have significantly improved. Researches on the factors that influence renewable energy production are available. However, we are unaware of any previous research that examines the role of renewable energy innovation in the promotion of renewable energy production. As a result, this study evaluates the impact of technical innovation on green growth from 1993 to 2018, while accounting for real GDP, producer price index, and CO emissions. Due to their pivotal status among the developing countries, our study has focused on the BRICS countries. By using a new panel quantile regression augmented with the method of moments, the empirical findings suggest that the influence of renewable energy innovation on renewable energy production is significantly positive across all quantiles. Moreover, the coefficients are generally bigger at the small quantiles, which suggests that countries with smaller renewable energy production per capita (India and South Africa) have a higher probability to experience a greater impact of renewable energy innovation per capita than countries with bigger renewable energy production per capita (Brazil and Russia).
可再生能源的进步是实现长期可持续发展最有效的技术之一，全球各国都在努力改变其经济和产业结构，以促进绿色增长。随着第四次工业革命（4IR）的到来，包括可再生能源在内的绿色技术的可用性、可及性和使用性都有了显著提高。关于影响可再生能源生产的因素已有相关研究。然而，我们尚未发现之前有任何研究考察可再生能源创新在促进可再生能源生产中的作用。因此，本研究评估了1993年至2018年技术创新对绿色增长的影响，同时考虑了实际国内生产总值、生产者价格指数和碳排放。由于金砖国家在发展中国家中的关键地位，我们的研究聚焦于金砖国家。通过使用一种新的面板分位数回归方法，并结合矩估计法，实证结果表明，可再生能源创新对可再生能源生产的影响在所有分位数上均显著为正。此外，系数在低分位数上通常更大，这表明人均可再生能源产量较低的国家（印度和南非）比人均可再生能源产量较高的国家（巴西和俄罗斯）更有可能在人均可再生能源创新方面受到更大的影响。
