アフリカ31カ国（1996-2024年）のパネルデータを用い、再生可能エネルギー消費と民主主義が生態学的フットプリントに与える影響を分析。再生可能エネルギーはフットプリントを削減し、民主主義はその効果を最大4倍増幅することを発見。環境クズネッツ曲線の転換点はGDP約11,850ドルで、多くの国は未だ上昇局面にある。政策への示唆として、クリーンエネルギー投資と民主的ガバナンスの同時強化を提言。
English
Using panel data from 31 African countries (1996-2024), this study analyzes the effects of renewable energy consumption and democracy on ecological footprint. Renewable energy reduces footprint, and democracy amplifies this effect up to fourfold. The Environmental Kuznets Curve turning point is at GDP per capita of about $11,850, with most nations still on the upward slope. Policy implications suggest simultaneous investment in clean energy and democratic governance.

📄 Abstract（原文）
ABSTRACT Mitigating the ecological footprint is essential for attaining global environmental sustainability, driving significant research into the factors that shape this broad measure of human demand on natural resources. Although previous studies have identified multiple determinants of ecological footprint, the combined effects and potential synergy between democratic governance and renewable energy consumption (REC) remain underexplored. This study fills this gap by investigating how democratic institutions and renewable energy adoption together influence ecological footprint across 31 African nations from 1996 to 2024, employing Driscoll‐Kraay standard errors, IV‐GMM estimators, and panel causality tests. Results reveal that renewable energy consumption significantly reduces ecological footprint, while democracy's direct effect is conditional: it is positive at low renewable penetration but turns negative as clean energy expands. The central contribution is a negative and significant interaction term, indicating that democratic institutions enhance the environmental benefits of renewable energy. At the highest democracy levels, a 1% increase in renewable energy reduces the footprint by approximately 0.50%, compared to only 0.12% at the lowest democracy levels—a fourfold amplification. The Environmental Kuznets Curve hypothesis is validated by a turning point at a GDP per capita by approximately $11,850 GDP, where most African nations remain on the upward slope. A bidirectional causality links renewable energy and ecological footprint is found. These findings imply that simultaneous investment in renewable infrastructure and democratic governance is essential, with renewable expansion requirements varying depending on institutional quality. Policy strategies should therefore couple clean energy deployment with transparency and accountability mechanisms to maximise environmental returns.
