本研究は49カ国（2000-2023年）のパネルデータを用い、バイオエネルギー特許とCO2排出量の同時決定を検証。NDCは発展途上国でバイオエネルギー特許を促進するが、先進国では負の効果。EKC仮説に反し、所得増で排出が再上昇する可能性を示唆。政策は開発段階に応じた対応が必要。
English
Using panel data from 49 countries (2000-2023), this study simultaneously estimates bioenergy patents and CO2 emissions. NDCs spur bioenergy patenting in developing countries but have negative effects in developed ones. Contrary to EKC, emissions may rise with income. Policy should be development-sensitive, promoting R&D in developed and technology transfer in developing economies.

📄 Abstract（原文）
Innovations in bioenergy are a key tool for reducing carbon dioxide (CO₂) emissions and are critical to achieving Nationally Determined Contributions (NDCs) under the Paris Agreement. However, existing research largely relies on single-equation specifications in which innovation is treated as exogenous to emissions, with little testing of their joint determination. This study addresses this by simultaneously estimating the relationship using established econometric methods. The balanced panel dataset covers 49 countries (26 developed, 23 developing) from 2000 to 2023 and examines CO₂ emissions per capita and bioenergy patents together. Results indicate statistically significant effects in both directions: reducing CO₂ emissions reduces bioenergy innovation, and larger increases in CO₂ emissions reduce bioenergy patenting. NDC commitments trigger bioenergy patenting in developing economies but have a negative net effect in developed economies, consistent with reduced policy effectiveness in countries with more mature innovation systems. Contrary to the Environmental Kuznets Curve (EKC), the relationship between income and emissions suggests that emissions may rise again as income continues to increase. Many developing economies exhibit high biomass potential but low institutional capacity. Policy approaches should be development–sensitive, highlighting frontier research and development (R&D) and innovation diversification in developed economies, while stimulating targeted technology transfer, NDC-linked finance, and R&D capacity building in developing economies.
