2000〜2021年の140カ国（先進国49、途上国91）のパネルデータを用い、操作変数分位点回帰により、再生可能エネルギー、生産能力構成要素、気候政策不確実性が持続可能な開発に与える不均一な影響を分析。再生可能エネルギーは先進国では全分位で正の効果を持つが、途上国では下位分位で負の効果を示し、上位分位で正に転じる。気候政策不確実性は全サンプルで負の効果を持ち、特に途上国で顕著。人的資本やICTは普遍的に正の効果を持ち、構造変化も強い正のドライバーである。

Using a panel of 140 countries (49 developed, 91 developing) from 2000-2021 and instrumental variable quantile regression, this study analyzes the heterogeneous impacts of renewable energy, productive capacity components, and climate policy uncertainty on sustainable development. Renewable energy has a consistently positive effect in developed nations but a quantile-dependent effect in developing ones: negative at lower quantiles and positive at higher quantiles. Climate policy uncertainty is universally negative, particularly harming developing countries. Human capital and ICT are robust positive drivers, while structural change also strongly promotes sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の文脈では、再生可能エネルギー推進の効果が先進国として確認されているが、途上国の開発段階に応じた効果の違いは、日本のODAや国際協力における再エネ支援戦略に示唆を与える。また、気候政策の不確実性が投資に悪影響を及ぼす点は、日本の長期エネルギー計画の安定性の重要性を裏付ける。
In the global GX context
Globally, this paper underscores that climate policy uncertainty is a major barrier to green investment, reinforcing the need for stable policy frameworks like those advocated by TCFD and ISSB. The finding that renewable energy effects vary by development level informs differentiated strategies for developed and developing economies in the transition to net-zero.
👥 読者別の含意
🔬研究者:The quantile regression approach reveals heterogeneous effects of renewable energy and policy uncertainty, offering a nuanced perspective for empirical research on sustainable development.
🏛政策担当者:Policymakers should note that reducing climate policy uncertainty is critical to attracting green investment, and renewable energy policies must be tailored to a country's development stage.
📄 Abstract（原文）
Achieving sustainable development requires understanding the complex drivers that operate across environmental, economic, and social domains. This research investigates the heterogeneous impacts of renewable energy, productive capacity components, and climate policy uncertainty on sustainable development. Analyzing a global panel of 140 countries (49 developed, 91 developing) from 2000 to 2021, it employs an instrumental variable quantile regression to capture differential effects across the distribution of sustainable development. The findings reveal a nuanced impact of renewable energy. For the full sample and for developed nations, renewable energy exhibits a consistently positive and statistically significant effect across all quantiles. In developing countries, however, the relationship is quantile-dependent: the impact is significantly negative for nations at the lower quantiles of sustainability but becomes positive for more advanced developing nations at the upper quantiles. Climate policy uncertainty has a universally negative effect, acting as a major barrier to green investment worldwide, with the most acute effects felt in the developing world. In contrast, human capital and ICT emerge as robust, universal pillars, demonstrating a consistently positive impact. The effects of natural capital are dualistic, following a curse-to-blessing trajectory, its impact shifts from significantly negative in less sustainable nations to positive in sustainability leaders. Structural change is a powerful, positive driver in all contexts. Meanwhile, the influence of institutions is a critical catalyst for progress at low-to-median development levels, though it exhibits diminishing returns for advanced nations. The private sector's impact is generally negative but turns positive in the most advanced developing countries. Also, the effect of transport is negative in most quantiles.
