61カ国・2002〜2024年のパネルデータを用い、グリーン技術革新（GTI）がエネルギー安全保障に与える影響をコピュラモデリング、モーメント分位点回帰、分位点ランダムフォレストで分析。GTIは全分位でエネルギー安全保障を改善し、特にエネルギー脆弱国で効果が大きい。エネルギー効率向上と再生可能エネルギー導入を通じ化石燃料依存を減らすが、制度・インフラが整った先進国・OECD諸国で便益がより大きい。政策はGTIを環境目的だけでなく安全保障の鍵として位置づけるべきと提言。
English
Using panel data for 61 economies (2002–2024), this study examines how green technological innovation (GTI) affects energy security via copula modeling, method-of-moments quantile regression, and quantile random forest. GTI improves energy security across all quantiles, with larger gains in energy-vulnerable nations, by boosting efficiency and renewable adoption to cut fossil-fuel dependence. Benefits are greater in developed/OECD economies with strong institutions and infrastructure. The authors urge integrating GTI into energy security policy, green R&D investment, and technology transfer.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はエネルギー自給率が低く、GX推進・エネルギー安全保障は経済安全保障と直結する。本論文はGTIが輸入依存を減らし安全保障を高めることを示し、日本のGX政策・技術開発投資の根拠として参照価値がある。
In the global GX context
Amid geopolitical energy shocks and the European crisis, this paper quantifies GTI's role in energy security across 61 economies, reinforcing the global narrative that decarbonization and energy security are complementary. It supports policy alignment seen in ISSB/TCFD-adjacent transition planning and national energy security strategies.

📄 Abstract（原文）
The global energy security is facing increasing challenges. Most economies still depend largely on imports of fossil fuels, and geopolitical tensions make them vulnerable to supply shocks and price fluctuations. The current energy crisis in Europe has demonstrated the quick transmission of such shocks across borders. The Green Technology Innovation (GTI) can tackle such challenges through diversification of energy sources, minimizing reliance on energy imports, and enhancing the domestic energy production capabilities. But the role of GTI in this context has received comparatively little scholarly consideration. The present paper examines the impact of GTI on energy security using panel data for 61 countries over the period of 2002–2024. To estimate the non-linear dependence, we use copula modeling, Method of Moments Quantile Regression, and Quantile Random Forest. Findings reveal that the GTI has significant contributions to the enhancement of energy security in all quantiles, with more improvements among energy-vulnerable nations. The GTI can enhance energy security in two different ways. It enhances energy efficiency and reduces dependence on fossil fuels through rapid adoption of alternative and renewable energy sources. However, developed and OECD nations benefit more because of strong institutional and infrastructural development. This study has important policy implications. Energy security policies should include GTI not just for environmental purposes but rather as the key to achieving energy security. Continuous investments in green R&D, transferring technology from developed to developing nations, and the inclusion of innovation policies in energy security plans are important.
