本研究は、EU26か国を対象に、グリーン投資とR&Dが再生可能エネルギー拡大とCO2排出削減に与える影響を分析。固定効果回帰と閾値分析の結果、投資は逆U字型の効果を持ち、制度の質がその効果を増幅することを示した。
English
This study examines how green investment and R&D affect renewable energy and CO2 emissions across 26 EU countries from 2004-2023. Using fixed-effects and threshold models, it finds an inverted U-shaped relationship for investment, with institutional quality amplifying effects.

日本のGX文脈において
日本でも地域間格差や制度の質が脱炭素政策の効果に影響する可能性があり、本稿の閾値分析の手法は参考になる。ただし、直接的な日本向け政策含意は限定的。
In the global GX context
The paper provides empirical evidence on how institutional quality moderates the effectiveness of green investment and R&D, offering insights for designing differentiated climate policies. Relevant for global discussions on investment thresholds and governance in energy transitions.

📄 Abstract（原文）
Abstract The European Union faces persistent disparities in its progress toward climate neutrality, despite unified policy frameworks under the Green Deal and Fit for 55. A key unresolved policy challenge is understanding why investment support and R&D efforts accelerate decarbonization in some countries but produce weaker outcomes in others. Existing research offers fragmented insights and rarely evaluates whether investment and innovation effects depend on institutional conditions or nonlinear thresholds. This creates a critical gap: the EU still lacks evidence on the mechanisms through which investment capacity, innovation activity, and governance jointly shape national decarbonization pathways. To address this gap, the study examines how green investment (proxied by greenfield FDI) and R&D influence renewable energy development and CO₂ emissions in 26 EU member states from 2004 to 2023. Fixed-effects regressions, moderation models, and panel threshold techniques are applied to capture both institutional conditioning and potential nonlinearities in the decarbonization process. The empirical results show that both green investment and R&D activity contribute to decarbonization, promoting renewable energy expansion and reducing CO₂ emissions. Green investment displays an inverted U-shaped relationship with emissions, indicating the presence of a threshold beyond which financial flows become more effective. Institutional quality significantly amplifies the effects of both investment and R&D, strengthening their contribution to the energy transition. These findings reveal that investment and innovation do not generate uniform outcomes across the EU; instead, their impact depends on reaching critical investment levels and on the strength of national governance systems. By identifying the structural and institutional mechanisms that shape decarbonization pathways, the study provides actionable evidence for designing differentiated, country-specific climate and investment policies within the EU.
