日本語

本研究は、グリーンファイナンス、ブルーエコノミー指数、クリーンエネルギー資産、エネルギー商品間の相互連関をTVP-VARと分位点VARモデルで分析。2021年10月から2024年1月のデータを用い、高い連関度(90~100%)を確認。クリーンエネルギー指数が主要な送信者、石油・ガスが受信者であり、ストレス期に非線形リスク伝達が顕著。投資家や政策立案者に、グリーンファイナンスとエネルギー政策の整合、リスク管理の強化、公正な移行のための国際協力を示唆。

English

This study examines the interconnectedness between green finance, blue economy indices, clean energy assets, and energy commodities using TVP-VAR and quantile VAR models from October 2021 to January 2024. Results show high connectedness (90–100%), with clean energy indices as key transmitters and oil/gas as net receivers, especially during stress periods. Spillover asymmetries across quantiles confirm non-linear risk transmission. Findings inform investors and policymakers on aligning green finance with energy policy, enhancing risk management, and promoting global cooperation for a just transition.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではグリーンファイナンスとエネルギー政策の連携が進む中、本論文の分析手法(TVP-VAR、分位点VAR)は、日本の再生可能エネルギー市場やカーボンプライシング導入後のリスク伝達分析に応用可能。特に、ストレス期における非線形リスクの把握は、日本の機関投資家のポートフォリオ管理や、SSBJ開示における気候リスク分析に示唆を与える。

In the global GX context

This paper contributes to global GX scholarship by empirically demonstrating the non-linear risk transmission between green finance and energy commodities, which is crucial for transition finance and climate risk management. The quantile VAR approach offers a methodological advancement for analyzing tail-risk spillovers, relevant for TCFD/ISSB scenario analysis and stress testing. The findings support the integration of green finance into energy policy and highlight the need for international cooperation in just transition.

👥 読者別の含意

🔬研究者:Provides a novel quantile VAR framework for analyzing non-linear spillovers between green finance and energy markets, useful for further research on climate risk transmission.

🏢実務担当者:Offers insights for portfolio diversification and risk management by showing that clean energy indices act as risk transmitters, while oil/gas are receivers during stress.

🏛政策担当者:Highlights the interconnectedness of green finance and energy commodities, suggesting that policies promoting clean energy can reduce systemic risk and support a just transition.

📄 Abstract(原文)

The post-COVID era highlights the need for sustainable, resilient economies. This study investigates the interconnectedness between green finance, blue economy indices, clean energy assets, and energy commodities using a TVP-VAR and quantile VAR model from October 2021 to January 2024. Results show high connectedness (90–100%), with clean energy indices (OCEN, GNR) as key transmitters and oil/gas as net receivers, especially during stress periods. Spillover asymmetries across quantiles confirm non-linear risk transmission. Findings inform investors and policymakers on aligning green finance with energy policy, enhancing risk management tools, and promoting global cooperation for a just transition. This framework supports forward-looking, sustainable financial and energy strategies.
