日本語

本研究は、2000年から2023年のインドネシアを対象に、経済成長とCO2排出の関係において再生可能エネルギーとエネルギー効率が果たす媒介効果をPLS-SEMで分析。経済成長は排出を有意に増加させる一方、再生可能エネルギーとエネルギー効率は排出削減に寄与し、特に産業部門の効率改善が運輸部門より効果的であることを示した。貿易開放度と制度の質が政策効果を高めることも確認。

English

This study empirically analyzes the mediating roles of renewable energy and energy efficiency in the economic growth-CO2 emissions nexus for Indonesia (2000-2023) using PLS-SEM. Economic growth significantly increases emissions, while renewable energy and energy efficiency reduce them, with industrial energy efficiency showing stronger mitigation than transport. Trade openness and institutional quality moderate policy effectiveness.

日本のGX文脈において

インドネシアの事例は、日本が関与する国際的な脱炭素協力や、ASEAN地域のエネルギー政策立案に示唆を与える。特に産業部門の効率改善と制度の質の重要性は、日本の技術協力や投資判断にも役立つ知見。

In the global GX context

This paper contributes to the global literature on decarbonization pathways in emerging economies by quantifying the mediating effects of renewables and energy efficiency. Its sectoral insights (industry vs. transport) and moderation by institutional quality are relevant for designing integrated climate policies in developing countries.

📄 Abstract(原文)

The transition toward low-carbon development has emerged as a critical global agenda, especially for developing countries like Indonesia, which are heavily reliant on fossil fuels. This study investigates the mediating role of renewable energy and energy efficiency in the relationship between economic growth and carbon emissions in Indonesia from 2000 to 2023. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the study finds that economic growth significantly increases carbon emissions, while both renewable energy and energy efficiency exert a negative impact on emissions. Moreover, these two variables partially mediate the growth–emissions nexus, with energy efficiency showing a stronger mitigation effect than renewable energy. The research also highlights that industrial energy efficiency yields greater emission reductions compared to the transport sector. Moderating effects of trade openness and institutional quality are found to enhance the effectiveness of energy policies. The study concludes that a combined strategy involving clean energy adoption, sectoral energy efficiency, and institutional reform is essential for achieving Indonesia's low-carbon development goals. The findings contribute both theoretically and practically to the literature on decarbonization and sustainable energy transitions in emerging economies.
