This paper presents an energy efficiency assessment of 46 African countries and analyzes possible bidirectional relationship between energy efficiency and economic development within a three-stage framework. In the first stage, energy efficiency is measured within a total factor framework using the slack-based measure with undesirable output and sub-regional comparisons are done. The second stage assesses the determinants of energy efficiency in Africa by way of a bootstrapped truncated regression. The third stage tests the reverse causal relationship between energy efficiency and economic development using 2-stage least squares. The results showed African countries to be on average, 56% energy efficient within the study period. Other African sub-regions could adopt the energy efficiency policies of North Africa as benchmark to improve energy efficiency. Economic development and technological progress are found to have significant positive effects on energy efficiency of African countries, while higher energy prices lead to higher inefficiency. Also, a bi-causal relationship is found to exist between total factor energy efficiency and economic development, giving support to the concept of sustainable development and confirming the International Energy Agency’s assertion on the positive macroeconomic impacts of energy efficiency. African countries are therefore, encouraged to invest in energy efficiency technologies and policies to drive sustainable economic development.

非洲全要素能源效率与经济发展

本文介绍了对46个非洲国家的能效评估,并在三个阶段的框架内分析了能效与经济发展之间可能的双向关系。在第一阶段,使用基于松弛的度量在不希望有的产出的情况下,在全要素框架内测量能源效率,并进行次区域比较。第二阶段通过自举截短回归法评估非洲能源效率的决定因素。第三阶段使用两阶段最小二乘法检验能源效率与经济发展之间的反向因果关系。结果表明,在研究期内,非洲国家的能源效率平均为56%。其他非洲次区域可以采用北非的能源效率政策作为提高能源效率的基准。人们发现,经济发展和技术进步对非洲国家的能源效率产生了显着的积极影响,而能源价格上涨导致效率降低。此外,发现全要素能源效率与经济发展之间存在因果关系,这为可持续发展的概念提供了支持,并确认了国际能源署关于能源效率对宏观经济的积极影响的主张。因此,鼓励非洲国家投资于节能技术和政策,以推动可持续的经济发展。人们发现,经济发展和技术进步对非洲国家的能源效率产生了显着的积极影响,而能源价格上涨导致效率降低。此外,发现全要素能源效率与经济发展之间存在因果关系,这为可持续发展的概念提供了支持,并确认了国际能源署关于能源效率对宏观经济的积极影响的主张。因此,鼓励非洲国家投资于节能技术和政策,以推动可持续的经济发展。人们发现,经济发展和技术进步对非洲国家的能源效率产生了显着的积极影响,而能源价格上涨导致效率降低。此外,发现全要素能源效率与经济发展之间存在因果关系,这为可持续发展的概念提供了支持,并确认了国际能源署关于能源效率对宏观经济的积极影响的主张。因此,鼓励非洲国家投资于节能技术和政策,以推动可持续的经济发展。支持可持续发展的概念,并确认国际能源机构关于能源效率对宏观经济的积极影响的主张。因此,鼓励非洲国家投资于节能技术和政策,以推动可持续的经济发展。支持可持续发展的概念,并确认国际能源机构关于能源效率对宏观经济的积极影响的主张。因此,鼓励非洲国家投资于节能技术和政策,以推动可持续的经济发展。
