日本語

本論文は、2000〜2023年のチュニジアの四半期データを用いて、持続可能な金融、エコイノベーション、エネルギーミックスが炭素強度に与える影響を実証分析した。結果、持続可能な金融は全排出状態で炭素強度を低下させ、再生可能エネルギーの比率拡大も効果的である一方、化石燃料の使用は炭素ロックインを強化する。エコイノベーションは高排出時に効果が高く、技術普及の遅れが示唆される。

English

Using quarterly data from Tunisia (2000-2023), this paper econometrically analyzes how sustainable finance, eco-innovation, and energy mix affect carbon intensity. Findings show sustainable finance consistently reduces carbon intensity, renewable energy share lowers it, while fossil fuel use reinforces carbon lock-in. Eco-innovation has stronger effects in high-emission states, indicating delayed technology diffusion.

日本のGX文脈において

日本では、SSBJ開示やトランジション・ファイナンスの拡大が進む中、新興国・MENA地域の実証研究は、日本の投資家や企業が海外展開や資金調達を検討する際の参考になる。特に、持続可能な金融の効果が排出量の高い状態で顕著である点は、日本の政策立案や企業戦略に示唆を与える。

In the global GX context

This paper contributes to global GX scholarship by providing empirical evidence from a MENA economy on the role of sustainable finance and eco-innovation in decarbonization. It aligns with global discussions on transition finance and the effectiveness of green financial instruments in emerging markets, offering insights for international investors and policymakers.

📄 Abstract（原文）

Many emerging economies seek to lower carbon intensity while remaining heavily dependent on fossil fuels. This paper examines how sustainable finance, eco-innovation, and the energy mix shape Tunisia’s low-carbon transition. We use quarterly data for 2000–2023 and an econometric environmental-impact model that links carbon intensity to green finance, innovation, renewable and fossil energy, openness, income, and demographic factors. The results show that sustainable finance consistently reduces carbon intensity across all emission states, with stronger effects when emissions are high. The energy mix is crucial: a larger share of renewable energy lowers carbon intensity, while higher fossil energy use increases it and reinforces fossil carbon lock-in. Eco-innovation has its strongest mitigation effects in high-intensity situations, suggesting delayed effects linked to limited absorptive capacity and technology diffusion. Openness and demographic pressure tend to raise emissions through scale and consumption channels. Overall, the findings depict a finance-anchored but energy-constrained transition. They indicate that Tunisia and similar MENA economies can accelerate decarbonization by scaling credible sustainable finance instruments, speeding up renewable deployment, and strengthening the innovation and governance framework that supports green investment, innovation policy, and energy sector reform in semi-industrialized economies.
