This study aims to provide a decomposition analysis on aggregate energy intensity in Ethiopia over 1990–2017 using Logarithmic Mean Divisia Index (LMDI) I decomposition method. It also investigates the main driving forces influencing the observed energy intensity trend in the presence of a structural break. The LMDI I decomposition results indicate that the efficiency component has played a prominent role in reducing the overall energy intensity while the contribution of structural component for the change in total intensity has been very negligible. On the other hand, the model estimation results with structural break invariably confirm that economic growth, modern renewable energy, and institutional quality appear to have a significant negative effect on total energy intensity in the long run (contribute positively for energy efficiency improvement) while industrialization and FDI stock tend to induce higher energy intensity. Further, modern renewable energy negatively moderates the effect of growth and industrialization on energy intensity. After all, the results suggest the need for giving a strong emphasis for sector-specific energy efficiency which may have an important implication not only on economic growth but also on environmental sustainability. Policy measures promoting clean energy transformation and better institutional setup also need to be highly encouraged.

这项研究的目的是使用对数平均Divisia指数（LMDI）I分解方法对埃塞俄比亚在1990-2017年间的总能量强度进行分解分析。它还研究了在存在结构性断裂的情况下影响观察到的能量强度趋势的主要驱动力。LMDI I分解结果表明，效率成分在降低总能量强度方面起着重要作用，而结构成分对总强度变化的贡献却可以忽略不计。另一方面，具有结构性断裂的模型估计结果始终证实了经济增长，现代可再生能源，长期来看，机构质量似乎对总能源强度有显着的负面影响（为提高能源效率做出积极贡献），而工业化和外国直接投资存量往往会诱发更高的能源强度。此外，现代可再生能源不利地减缓了增长和工业化对能源强度的影响。毕竟，结果表明需要特别强调特定部门的能源效率，这不仅对经济增长而且对环境的可持续性都具有重要意义。还必须高度鼓励促进清洁能源转型和更好的机构设置的政策措施。现代可再生能源不利地减缓了增长和工业化对能源强度的影响。毕竟，结果表明需要特别强调特定部门的能源效率，这不仅对经济增长而且对环境的可持续性都具有重要意义。还必须高度鼓励促进清洁能源转型和更好的机构设置的政策措施。现代可再生能源不利地减缓了增长和工业化对能源强度的影响。毕竟，结果表明需要特别强调特定部门的能源效率，这不仅对经济增长而且对环境的可持续性都具有重要意义。还必须高度鼓励促进清洁能源转型和更好的机构设置的政策措施。
