本報告は、2050年までのグローバルサウスが先進国との所得格差を縮小できるかは、技術や資本の利用可能性ではなく制度の吸収能力(D係数)と気候・金融ショックへの耐性に依存すると論じる。技術普及・クリーンエネルギー拡大・気候適応・経済収斂の4移行が相互に作用し、低吸収能力・累積負担・ショック曝露が掛け合わさる「複合脆弱性乗数」が開発を可逆的にしうる。適応資金は年間310〜365億ドル必要に対し26億ドルしか流れず12〜14倍のギャップがある。LEAP枠組み(活用・電化・適応・推進)を提案し、収斂は政策次第で達成可能だが条件付きだと結論づける。
English
This report argues that whether the Global South closes the income gap by 2050 depends less on technology or capital availability than on institutional absorptive capacity (the D-Coefficient) and resilience to climate and financial shocks. Four coupled transitions—technology diffusion, clean-energy build-out, adaptation, and convergence—interact through a Compound Vulnerability Multiplier that can make development reversible. Adaptation needs of US$310–365bn/year face only US$26bn in flows (a 12–14× gap). It proposes the LEAP framework (Leverage, Electrify, Adapt, Propel), concluding convergence is achievable but conditional on policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとっては、グローバルサウスの適応資金ギャップやクリーンエネルギー投資の偏在が、移行金融・インフラ輸出・サプライチェーン強靱化の文脈で直接的な事業機会とリスクを示す。SSBJや有報での気候関連開示を進める上でも、途上国における物理的リスクと適応策の評価は重要になる。
In the global GX context
For global disclosure scholarship, this report links adaptation finance gaps and skewed clean-energy investment to the broader TCFD/ISSB agenda, highlighting that transition and physical risk assessments must account for Global South absorptive capacity. It adds a development-economics lens to transition finance debates, where adaptation funding shortfalls (12–14×) remain largely absent from corporate climate disclosure frameworks.

📄 Abstract(原文)
The report argues that the next quarter‑century will determine whether the Global South meaningfully closes the income gap with advanced economies or merely prevents it from widening. Convergence is technically achievable at unprecedented scale, but fragile, because it depends not on the availability of technology or capital but on the absorptive capacity of institutions — the D‑Coefficient — and the ability to protect gains against climate and financial shocks.The report identifies four simultaneous transitions as the coupled system shaping mid‑century outcomes:Technology diffusion, now arriving faster than ever but still constrained by adoption gaps. As the report notes, “The technology arrives; the capacity to use it lags.”Clean‑energy build‑out, where solar costs have collapsed but investment remains geographically skewed, with the Global South ex‑China attracting under 15% of global clean‑energy capital.Climate adaptation, chronically underfunded, with developing‑country needs of US$310–365 billion per year versus US$26 billion in current flows — a 12–14× gap.Economic convergence, which emerges only when the first three transitions reinforce rather than undermine one another.These transitions interact through the Compound Vulnerability Multiplier, defined as the multiplicative effect of low absorptive capacity, high cumulative burden (the P‑Integral), and dense exposure to climate and economic shocks. When the multiplier is high, “negative shocks subtract from the development stock faster than diffusion and investment add to it,” making development reversible.The report outlines three convergence trajectories to 2050 — fast, baseline drift, and stalled — with outcomes driven by capacity, clean‑energy access, and adaptation rather than raw growth rates. Demography is decisive: Africa’s working‑age population will nearly double to ~1.6 billion, offering either a historic dividend or a destabilizing burden depending on institutional readiness.To navigate this environment, the report proposes the LEAP Framework — Leverage, Electrify, Adapt, Propel — a portfolio approach in which the weakest pillar sets the ceiling for all others. Diffusion without capacity produces stranded assets; electrification without adaptation yields reversible gains; growth without institutional propulsion concentrates rather than converges.The central claim: Convergence is achievable but conditional, and the conditions are within reach of policy. The outcome is not fated — it is engineered through absorptive capacity, clean‑energy financing, climate resilience, and institutional strength.
