本研究は、2002～2022年の低中所得国（LMICs）において、気候ファイナンス（適応・緩和資金）が再生可能エネルギー普及に与える効果を分析。MMQRとGMM推定により、気候ファイナンスは特に吸収能力が中程度以上の国で有意な促進効果を持つことを示した。経済発展やマクロ経済の安定性が効果の条件であることも明らかに。

English

This study evaluates the impact of climate finance on renewable energy transitions in low- and middle-income countries (2002-2022) using MMQR and GMM methods. Results show that climate finance significantly promotes renewable energy adoption, especially in countries with moderate to high absorptive capacity. Effectiveness depends on macroeconomic stability and institutional readiness.

📄 Abstract（原文）

ABSTRACT Achieving SDG 7 requires substantial financial flows that can enable low‐ and middle‐income countries (LMICs) to expand renewable energy and reduce dependence on carbon‐intensive systems. This study evaluates whether climate finance—specifically adaptation funding, mitigation funding, and total climate‐related financial flows—effectively drives renewable energy transitions in LMICs from 2002 to 2022. Using the Method of Moments Quantile Regression (MMQR) combined with Driscoll–Kraay standard errors and System GMM estimation to address robustness and potential endogeneity concerns, the findings reveal that climate finance significantly enhances renewable energy adoption, with the strongest effects observed at the median and higher quantiles. This suggests that climate finance is most impactful in countries that already possess moderate to strong absorptive capacity and institutional readiness. The findings further reveal that the impact of climate finance is conditional on economic development, as interaction and subsample analyses show stronger effects in countries with higher absorptive capacity. Among the control variables, GDP per capita and population scale consistently promote renewable energy growth, while inflation acts as a barrier by increasing investment uncertainty. Natural resource rents remain insignificant, indicating that resource‐rich economies often fail to channel extractive revenues toward sustainable energy pathways. Overall, the results confirm that climate finance is a crucial catalyst for advancing SDG 7 in LMICs, but its effectiveness depends on stable macroeconomic conditions, institutional reforms, and policies that ensure equitable and inclusive access to clean energy.
