タンザニアとベトナムの全国世帯パネル（2008〜2020年）を用い、多次元エネルギー貧困指数で貧困の発生率・強度・分布の変化を分析した。両国とも改善したが、タンザニアは電化が進んでも広範な貧困が残り、ベトナムは急速な改善後に残存的・集中的な貧困へ移行した。調理用燃料の非クリーン性が最も根強い剥奪であり、所得・教育・都市居住が低貧困と相関する。電化政策とクリーン調理移行を区別した政策設計を提言する。
English
Using nationally representative household data from Tanzania and Vietnam (2008–2020), the authors track multidimensional energy poverty across incidence, intensity, dimensions and distribution. Both countries improved, but Tanzania showed broad persistence despite electrification gains, while Vietnam shifted to residual, concentrated deprivation. Unclean cooking fuel was the most persistent deprivation; income, education, urban residence and non-farm work correlated with lower deprivation. The paper argues policy must separate electrification from clean-cooking transitions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、公正な移行（just transition）やエネルギーアクセス格差を論じる際の国際比較エビデンスとして参照価値がある。国内の再エネ導入・電化政策における地域格差や低所得世帯支援の議論にも示唆を与える。
In the global GX context
Adds to the global just-transition and SDG7 literature by showing that energy access gains do not automatically translate into reduced multidimensional deprivation, and that clean-cooking remains the binding constraint. Relevant to development finance and transition-finance frameworks that increasingly require social co-benefits and equity metrics.

📄 Abstract（原文）
Expanding access to modern energy does not necessarily eliminate energy poverty. Even as incomes rise and energy access improves for many households, others may continue to experience deprivation across essential energy services. Yet relatively little is known about the forms this persistence takes and how they differ across energy-transition contexts. Using nationally representative household data from Tanzania and Vietnam from 2008 to 2020, we examine these patterns through a multidimensional energy poverty index. We assess changes in the incidence, intensity, dimensions, and distribution of energy poverty, estimate household-level correlates using Tobit and Logit models, and apply an Oaxaca-Blinder decomposition to the cross-country energy-deprivation gap. Energy poverty declined substantially in both countries, but persistence differed markedly. Tanzania exhibited broad persistence, with deprivation remaining widespread and severe despite major gains in electricity access, while Vietnam exhibited more residual and concentrated persistence following a rapid decline in aggregate energy poverty. Unclean cooking fuels remained the most persistent deprivation in both countries. Income, education, urban residence, and non-farm employment were associated with lower energy deprivation, while farming was associated with greater deprivation. Observable household characteristics accounted for 27.4% of the cross-country gap, indicating that differences in socioeconomic endowments alone do not account for the contrasting outcomes. Policy responses should therefore distinguish electrification from clean-cooking transitions and adapt targeting to the form of persistence. This requires broad multidimensional interventions where deprivation remains widespread and targeted support where it is residual and concentrated, particularly among rural and consumption-poor households and for persistent cooking deprivation.
