アフリカ43カ国・2000〜2022年のデータを用い、空間ダービンモデルで気候脆弱性・適応準備・ガバナンスが持続可能な開発に与える影響を分析。気候脆弱性は直接効果−0.352に加え、近隣国からの間接効果−1.243と総効果の78%を占める大きなスピルオーバーを示す。ガバナンスは正の直接効果を持つが波及効果はなく、適応準備は直接効果なし・間接効果のみ有意。開発課題の越境性を示し、地域協調の必要性を訴える。
English
Using a spatial Durbin model across 43 African nations (2000–2022), this paper shows climate vulnerability depresses sustainable development directly (−0.352) and, more strongly, through spillovers from neighboring countries (indirect −1.243, 78% of total effect). Governance has a positive direct effect but no spillover, while climate readiness shows only significant indirect effects. Findings underscore the transnational nature of development risk and the need for regional cooperation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業のGX実務・SSBJ開示への直接示唆は乏しいが、気候リスクが国境を越えて波及するという視点は、サプライチェーンを通じた間接的気候リスク評価や適応ファイナンスの議論に示唆を与える。
In the global GX context
While focused on Africa, the paper reinforces a core global disclosure theme: climate risk is spatially correlated and crosses borders, supporting TCFD/ISSB expectations that firms assess upstream and geographic climate risk beyond their own operations. It adds empirical weight to adaptation finance and regional cooperation arguments in the global GX agenda.

🔬研究者:空間計量経済学を用いた気候脆弱性と開発の波及効果の実証例として、適応・開発研究の方法論的参照になる。
🏢実務担当者:アフリカにサプライチェーンや事業拠点を持つ企業が、地域横断的な気候リスクと適応準備の評価に活用できる。
🏛政策担当者:国単位の適応策では不十分で、地域協調メカニズムの設計が必要という政策的含意を提供する。
📄 Abstract（原文）
ABSTRACT Climate change is projected to undermine the progress that Africa can make towards achieving the United Nations' Sustainable Development Goals (climate action—SDG 13). Although Africa accounts for less than 4% of the world's GHG emissions, the continent faces severe climate change impacts, including drought, floods, and desertification. In light of this scenario, this paper evaluates the effects of climate vulnerability, readiness, and governance on sustainable development across 43 African nations during 2000–2022 using the spatial Durbin model. Results show that climate vulnerability has a significant negative effect on development, with a direct effect of −0.352. More importantly, there are substantial spillover effects from nearby countries that surpass the direct effect (indirect effect: −1.243, representing 78% of the total effect). On the contrary, governance positively influences development, with a direct effect of β = 0.0007 and no spillover effect across nations. Lastly, although climate readiness did not have a significant direct impact on development, it had considerable spillover effects (indirect effect: −0.204). Overall, the findings highlight the transnational nature of developmental issues within Africa. These findings suggest the need for regional cooperation to address the risks posed by climate change. Climate change mitigation and adaptation efforts require regional responses in addition to national‐level strategies.
