本研究は、1995年から2021年までの20のOECD諸国を対象に、環境税と環境関連技術革新がエネルギー原単位に与える単独および相乗効果を、モーメント法分位点回帰（MMQR）を用いて分析した。結果、両者は単独でもエネルギー原単位を低下させるが、その相互作用がさらなる削減を促進し、特に高エネルギー原単位の国で効果が顕著であることを示した。市場ベースの政策手段が技術革新の効果を増幅することを実証し、政策統合の重要性を示唆している。
English
This study analyzes the individual and synergistic effects of environmental taxation and eco-innovation on energy intensity across 20 OECD countries from 1995 to 2021 using Method of Moments Quantile Regression. It finds that both factors reduce energy intensity independently, but their interaction amplifies the reduction, especially in countries with high energy intensity. The results demonstrate that market-based instruments enhance the effectiveness of green technologies, highlighting the importance of policy integration.

In the global GX context
This paper contributes to the global discourse on policy mix design for energy transitions, providing empirical evidence that combining environmental taxation with eco-innovation yields synergistic effects on energy intensity reduction. It supports the rationale for integrating carbon pricing with technology support policies, relevant for countries implementing carbon taxes or ETS under the Paris Agreement.

📄 Abstract（原文）
Despite the global urgency to decouple economic growth from energy intensity, the interactive role of regulatory frameworks and technological progress in energy efficiency transitions remains inadequately understood. Hence, this study investigates the standalone and synergistic impacts of environmental taxation (ET) and environmentally related technology innovation (ERTI) on energy intensity (EI) across 20 OECD countries from 1995 to 2021. Utilizing a robust Method of Moments Quantile Regression (MMQR) framework with fixed effects, we transcend mean-based estimations to address distributional heterogeneity across various energy intensity quantiles. Our empirical findings unveil a significant joint effect: while environmental taxation and eco-innovation independently curb energy intensity, their interaction serves as a significant moderating catalyst. Specifically, fiscal instruments enhance the capacity of green technologies to lower energy intensity, with the most pronounced effects observed in higher quantiles. These results suggest that market-based instruments are not merely revenue-generating tools but are conducive to guiding sustainable technological development toward global energy efficiency goals. By providing a strategic roadmap for policy integration, this research offers critical insights for navigating the complex socio-technical dynamics of energy transitions within planetary boundaries.
