本研究は、2010年から2023年までの18のOECD諸国を対象に、研究開発投資と貿易開放性が再生可能エネルギー移行に与える影響を分析した。ブートストラップ分位回帰とCS-ARDL推定を用いた結果、R&D投資は低位・高位の移行段階で有意な正の効果を持ち、貿易開放性は十分な吸収能力がある場合にのみ効果的であることが示された。政策含意として、移行段階に応じたR&D強化、制度改革、貿易統合の重要性を提言している。

This study examines the joint effects of R&D investment and trade openness on renewable energy transition across 18 OECD countries from 2010 to 2023. Using bootstrap quantile regression and CS-ARDL, it finds that R&D has positive effects at low and high transition levels, while trade openness becomes significant only with sufficient absorptive capacity. Policy implications emphasize stage-specific R&D, institutional reforms, and trade integration for SDG 7 and 13.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はOECD加盟国として、本分析の対象に含まれる。再生可能エネルギー移行におけるR&D投資の重要性や貿易開放性の条件付き効果は、日本のエネルギー政策（特に第6次エネルギー基本計画や再生可能エネルギー導入目標）に示唆を与える。低移行段階でのR&D強化や、中・高移行段階での制度・貿易政策の調整が参考となる。
In the global GX context
This OECD-focused study offers cross-country evidence on renewable energy transition drivers, relevant for global climate policy. The finding that R&D is crucial at early and advanced stages, and trade openness requires absorptive capacity, informs international efforts like the Paris Agreement and SDG 7/13. It highlights the need for tailored policies across different transition stages.

📄 Abstract（原文）
ABSTRACT Persistent disparities in renewable energy transition across OECD economies—even among countries with similar income levels and institutional frameworks—raise critical questions about the drivers of clean energy adoption and their varying effects across transition stages. This study examines the joint effects of research and development (R&D) investment and trade openness on renewable energy transition across 18 OECD countries from 2010 to 2023, controlling for technological innovation, regulatory quality, carbon productivity, economic policy uncertainty, and energy prices. Bootstrap quantile regression captures heterogeneity across low‐, middle‐, and high‐transition economies, while the Cross‐Sectionally Augmented ARDL (CS‐ARDL) estimator ensures dynamic robustness. The findings reveal strong distributional differences. R&D investment has a significant positive effect at the lowest and highest quantiles, underscoring its role in initiating transition and driving frontier innovation at advanced stages. Trade openness becomes significant only from the 70th quantile, indicating a threshold where sufficient absorptive capacity is required for technology spillovers. Technological innovation and regulatory quality consistently enhance transition outcomes, while carbon productivity exerts a universal negative effect by reinforcing fossil fuel efficiency lock‐in. Economic policy uncertainty encourages renewable diversification in high‐transition economies as a hedge against fossil fuel risks. CS‐ARDL estimates confirm these results and show a long‐run adjustment speed of 71% annually. Policy implications suggest prioritizing R&D and institutional reforms in low‐transition economies, addressing carbon lock‐in in middle‐transition economies, and deepening trade integration and regulatory frameworks in high‐transition economies to sustain progress toward SDG 7 and SDG 13.
