タンザニア国家パネル調査5波（2008–2020）の441世帯バランスパネルを用い、調理燃料の移行を「エネルギーモビリティ」として分析。14.06%が着実に上昇、3.4%が後退、11.56%が変動し、エネルギーラダーモデルの線形仮定を否定。農村立地が「常に汚い燃料」に留まる最大の予測因子（+31.5ポイント）で、人的資本と所得がバイオマス依存脱却の鍵。PAYGガス等の継続的政策支援の必要性を示す。
English
Using five waves of Tanzania's National Panel Survey (2008–2020) and a balanced panel of 441 households, this study analyzes cooking-fuel transitions as 'energy mobility.' It finds bidirectional movement—14.06% steady climbers, 3.4% steady decliners, 11.56% fluctuating—challenging linear Energy Ladder assumptions. Rural location is the strongest predictor of remaining on dirty fuels (+31.5 pp), while human capital and income enable escape from biomass dependence. Sustained policy support such as Pay-As-You-Go gas is needed to prevent transition reversals.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では調理燃料移行は主要課題ではないが、途上国でのクリーン調理移行支援は日本のODA・JCM（二国間クレジット）やGX推進の国際貢献文脈と接点がある。移行の後退（reverse transition）リスクは、日本の省エネ政策における行動変容の持続性議論にも示唆を与える。
In the global GX context
This paper adds longitudinal evidence to the global energy-transition literature, showing that household fuel transitions are non-linear and reversible—a finding relevant to SDG7 and clean-cooking finance. It challenges the Energy Ladder Model that underpins many transition-finance assumptions in emerging markets, and highlights rural-urban inequality as a structural barrier that carbon finance and PAYG models must address.
👥 読者別の含意
🔬研究者:途上国世帯の燃料移行が非線形・双方向的であることを長期パネルで示し、エネルギーラダー仮説の限界を実証する。
🏢実務担当者:新興国市場でのクリーン調理燃料ビジネス（PAYGガス等）において、移行後退リスクと農村部の支払能力制約を考慮した設計が必要。
🏛政策担当者:調理燃料移行を一時的補助で終わらせず、農村部の所得・人的資本支援と組み合わせた継続的政策設計が不可欠。
📄 Abstract（原文）
This study examines the transition to cooking fuels among households in Tanzania, driven by the ongoing reliance on traditional fuels and the need for cleaner energy alternatives. Utilizing data from five waves of the Tanzania National Panel Survey (2008–2020), we analyze a balanced panel of 441 households to provide a unique longitudinal perspective on "energy mobility". Unlike previous cross-sectional studies, this research explicitly identifies bidirectional movement, revealing that while 14.06% of households were "steady climbers," 3.4% were "steady decliners" and 11.56% "fluctuated" between categories, challenging the linear assumptions of the Energy Ladder Model. Employing random effects ordered logit and multinomial logit models with clustered standard errors, we find that while firewood remains the dominant cooking fuel, there is a gradual shift towards transition fuels like charcoal, with limited adoption of clean fuels such as gas and electricity. Key findings reveal that rural location is the strongest predictor of remaining "always dirty" (increasing the probability by 31.5 percentage points), while human capital and income serve as critical stepping stones for breaking biomass dependence. Our findings provide a historical baseline for current interventions, highlighting the need for sustained policy support, such as Pay-As-You-Go for gas, to prevent transition reversals and address the deep-seated rural-urban inequality gap.
