Abstract

This study explores how governance effectiveness and economic inequalities influence the role of mineral resources and investments in advancing clean energy. It examines the long-term effects of mineral resources (imports, rents, and depletion) and investments (energy investment, industrial employment, and GDP share) on clean energy progress imbedded in installed solar capacity (ISC), installed wind capacity (IWC), and electricity generated from renewables (EGR). The study analyzes datasets from 1992 to 2021 across 51 countries, categorized by governance effectiveness and economic tiers, using a cross-sectional augmented distributed lags model. Key findings highlight that mineral imports and rents positively affect EGR and IWC from lower middle to high-income countries. These positive impacts occur across governance tiers ranging from weak to strong. Mineral depletion significantly affects EGR, ISC, and IWC across all governance and economic levels, though ISC and IWC effects vary. Energy investments boost EGR, while industrial employment and GDP yield mixed outcomes on ISC, IWC, and EGR. The findings highlight that as governance effectiveness and economic tiers improved, amplify the positive influence of mineral resources and energy investments on EGR. The study suggests targeted policies to optimize the role of mineral resources and investments in promoting clean energy development.

矿产资源和投资推动清洁能源进步：来自经济和治理效率层面的证据

本研究探讨了治理效率和经济不平等如何影响矿产资源和投资在推进清洁能源方面的作用。报告考察了矿产资源（进口、租金和耗竭）和投资（能源投资、工业就业和GDP份额）对太阳能装机容量（ISC）、风能装机容量（IWC）和可再生能源发电（EGR）所包含的清洁能源进展的长期影响。该研究使用横截面增强分布式滞后模型，分析了51个国家1992年至2021年的数据集，按治理效率和经济水平进行了分类。主要研究结果强调，从中低收入到高收入国家，矿物进口和租金对EGR和IWC有积极影响。这些积极的影响发生在从弱到强的各个治理层之间。矿产枯竭对EGR、ISC和IWC在所有治理和经济层面都有显著影响，尽管ISC和IWC的影响各不相同。能源投资促进了EGR，而工业就业和GDP对ISC、IWC万国表和EGR的影响参差不齐。研究结果强调，随着治理效率和经济层次的提高，矿产资源和能源投资对EGR的积极影响会放大。该研究建议有针对性的政策，以优化矿产资源和投资在促进清洁能源发展中的作用。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
