44カ国1990～2024年のパネルデータを用い、輸送由来CO₂排出量の決定要因を分析。再生可能エネルギー普及と技術革新は排出削減に有意な効果（弾力性-0.39、-0.61）を示し、制度の質が最も強力な長期削減要因（-1.07）である。EKC仮説を支持し、脱炭素には制度改革とグリーン技術普及の統合的施策が不可欠と結論。
English
This study analyzes transport CO₂ emissions across 44 countries (1990-2024), finding robust evidence for the Environmental Kuznets Curve. Renewable energy and innovation significantly reduce emissions (elasticities -0.39 and -0.61), while institutional quality is the strongest long-term mitigant (-1.07). The paper argues transport sustainability requires integrated policy reform, green technology diffusion, and systemic energy transformation.

📄 Abstract（原文）
<title>Abstract</title> <p>This study investigates the macro-structural determinants of transport-related CO₂ emissions for a global panel of 44 countries over the period 1990–2024. Adopting a second-generation econometric framework, the research employs the Augmented Mean Group (AMG) and PMG-ARDL estimators to account for cross-sectional dependence and slope heterogeneity. The empirical results provide robust evidence for the Environmental Kuznets Curve (EKC) hypothesis in the transport sector, identifying a non-linear inverted U-shaped relationship between economic growth and carbon intensity. Furthermore, the findings reveal that renewable energy penetration and technological innovation exert significant negative impacts on emissions, with elasticities of -0.39 and − 0.61, respectively. Notably, institutional quality emerges as the most potent long-term mitigant (-1.07), suggesting that governance frameworks are the primary catalysts for breaking carbon lock-in. The study concludes that achieving transport sustainability requires a synchronized policy mix that integrates deep institutional reform with green technological diffusion and systemic energy transformation.</p>
