日本語
マダガスカル農村部で太陽光マイクログリッドを展開するパイロット事業を、地域レベルのランダム化比較試験で評価した研究。2017〜18年と2023年の家計調査により、電力アクセスと照明・携帯充電などの近代的エネルギー利用が改善し、副業的な新規経済活動も生まれたことを示す。ただし家計の富への影響は限定的で、健康面は改善したが教育面では効果が見られず、理論的変化に含まれた補完的施策の未実施が示唆される。
English
An RCT evaluation of a solar micro-grid pilot in rural Madagascar, using household surveys in 2017–18 and 2023. It finds improved electricity access and modern energy use (lighting, phone charging) and some new secondary income activities, but limited wealth gains and mixed social outcomes—health improved, education did not. Unimplemented complementary actions in the theory of change may explain the gap.

📝 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、オフグリッド電化・分散型電源の社会実装を厳密に検証する手法（RCT）と、便益が限定的になりやすい要因の知見が参考になる。特にアジア・アフリカでのエネルギーアクセス事業やJCM等の案件形成において、効果測定設計の重要性を示す。
In the global GX context
Adds rigorous causal evidence to the distributed electrification literature, which has largely been descriptive. Relevant to global energy-access and just-transition finance debates, and to results-based financing design where measurable development impact is required.
👥 読者別の含意
🔬研究者:RCT設計と長期追跡調査により、マイクログリッドの開発効果に関する因果推論の厳密な事例を提供する。
🏢実務担当者:オフグリッド事業の便益は補完的施策なしには限定的になり得るため、事業設計時に社会・経済効果の実装計画を組み込むべき。
🏛政策担当者:農村電化政策では、電力供給だけでなく生産的利用や教育・保健サービスとの連携策を同時に設計する必要がある。
📄 Abstract（原文）
This paper evaluates the impact of a pilot innovative project aiming at promoting a replicable model to create access to distributed electricity in rural areas where grid extension is economically infeasible. The project proposes building solar-powered micro-grids to provide affordable electricity and basic electricity services to households, businesses, and public services. The pilot nature of the project was conceived to facilitate a rigorous testing of its developmental impacts, contrasting with the existing evaluation literature, which provides at best descriptive conclusions. The evaluation methodology is based on a randomized control trial (RCT) design, with data collected before and after project implementation through two waves of household surveys in 2017–2018 and 2023, complemented by locality data. The experimental dimension of the paper is based on a treatment implemented at the locality level. A dozen of comparable localities had been initially selected after a common pre-feasibility study as suitable for the project, and the project has been randomly implemented in only half of them. Findings reveal notable improvements in household access to electricity, particularly in the use of modern energy services like lighting and phone charging. The project has also triggered nascent new economic activities, especially secondary income-generating occupations, though the overall impact on household wealth remains limited. Social outcomes have seen mixed results, with only significant improvements in health and none in education. Complementary actions mentioned in the project's theory of change but not fully implemented may be needed to achieve the broader economic and social transformation initially anticipated.
