本研究は、63の途上国を対象に、グリーンODAとCO2排出の関係が再生可能エネルギー移行段階によって異なるかを動的パネル閾値回帰で分析。再生可能エネルギー消費が78.2%未満ではグリーンODAは排出増と関連し、閾値超後は効果が負に転じるが統計的に有意でない。援助効果は受入国の再生可能エネルギー発展段階に依存することを示唆。
English
This study examines whether the effect of Green ODA on CO2 emissions varies with renewable energy transition stages in 63 developing countries using dynamic panel threshold regression. It finds that renewable energy consumption is associated with lower emissions, but Green ODA's effect is positive below a 78.2% threshold and negative (though insignificant) above it, suggesting aid effectiveness depends on recipient countries' renewable energy development.

📄 Abstract（原文）
Green ODA supports renewable energy and low-carbon structural transformation. Limited studies have explicitly evaluated whether Green ODA reduces emissions or examined the structural conditions that enable climate-oriented aid to produce meaningful decarbonisation outcomes. In this study, we examined the relationship between Green ODA and carbon dioxide emissions and investigated whether this relationship differs across the stages of renewable energy transition. Using annual panel data for 63 developing countries selected from the OECD Development Assistance Committee (DAC) List of ODA Recipients, including low-income, lower-middle-income, and eligible upper-middle-income economies, between 2010 and 2021, a dynamic panel threshold regression model was employed, with renewable energy consumption as the threshold variable. Renewable energy consumption was significantly associated with lower carbon emissions. However, the effects of Green ODA varied depending on the level of renewable energy development. The estimated threshold value for renewable energy consumption was 78.2%. When renewable energy consumption remained below this threshold, Green ODA was associated with increased carbon emissions. Following threshold exceedance, the effect became negative, although it remained statistically insignificant. These findings suggest that the relationship between Green ODA and carbon emissions differs across the stages of renewable energy transition in recipient countries.
