豪州1996〜2021年のデータを用い、Kernel正則化最小二乗法（機械学習）でグリーンエネルギー金融と環境税が環境質に与える影響を分析。グリーン金融はGHG排出を有意に削減し、法の支配も排出抑制に寄与、両者の交互作用で更なる削減効果を確認。一方、環境税は排出と正の関係にあり、法の支配の下でその負の効果が強まる。経済成長は排出を増やすが閾値効果はEKC仮説を支持。
English
Using Australian data (1996–2021) and Kernel Regularized Least Squares machine learning, this study examines how green energy finance and environmental taxes affect environmental quality, moderated by rule of law. Green energy finance and rule of law both significantly reduce GHG emissions, with their interaction yielding additional reductions. Environmental taxes, however, correlate positively with emissions, intensifying under stronger rule of law. Economic growth raises emissions at lower income thresholds, supporting the EKC hypothesis.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGX推進法・GX経済移行債やカーボンプライシング（GX-ETS、炭素賦課金）の設計議論が進行中。本稿は「グリーン金融＋税＋法の支配」の組合せ効果を実証し、制度設計・ガバナンス整備の重要性を示す点で、日本の政策立案・投資家対応に示唆を与える。
In the global GX context
As ISSB/TCFD disclosure and carbon pricing expand globally, this paper links transition finance and fiscal instruments to actual emission outcomes, arguing governance quality (rule of law) is decisive. It adds empirical nuance to debates on whether carbon taxes alone deliver decarbonization, relevant to CSRD/ISSB-aligned policy design.
👥 読者別の含意
🔬研究者:グリーン金融・環境税・ガバナンスの交互作用を機械学習で扱う実証手法と、税の逆効果という非自明な結果を参考にできる。
🏢実務担当者:グリーン金融調達や炭素税対応を検討する際、制度・法の支配の質が実効性を左右する点をリスク評価に織り込む示唆。
🏛政策担当者:炭素税単独では排出削減に結びつかない可能性があり、グリーン金融・法制度・ガバナンスを組み合わせた政策パッケージ設計が重要。
📄 Abstract（原文）
ABSTRACT Anchored on the sustainable development goals (SDGs) and the Paris Agreement, which seek to limit the global average temperature to well below 2°C above pre‐industrial levels and pursue efforts to limit the temperature to 1.5°C, this study investigates how green energy finance and environmental taxes affect environmental quality, with an emphasis on the moderating role of the rule of law. Using data on Australia (1996–2021), the findings via the Kernel Regularized Least Squares machine learning technique show that green energy finance significantly reduces greenhouse gas emissions, promoting SDGs 13 and 7. The rule of law also enhances environmental quality by mitigating greenhouse gas emissions, contributing to SDGs 13 and 16. The interaction between the rule of law and green energy finance yields additional emission‐reducing effects. In contrast, environmental taxes are positively related to emissions, and this negative effect intensifies when conditioned on the rule of law, challenging SDG 13. Economic growth increases emissions, especially at lower income thresholds, which contradicts SDG 13; however, the threshold effect supports the EKC hypothesis. These outcomes highlight the crucial role of governance in aligning fiscal and environmental policies to achieve SDGs 7, 13, and 16, while also identifying policy misalignments that could hinder sustainable progress if left unaddressed.
