日本語
米国のインフレ削減法（IRA）の「エネルギーコミュニティ」条項が、化石燃料依存地域へのクリーンエネルギー投資を促進したかを検証。空間的に詳細なデータを用い、太陽光投資を有意に増加させたが、風力投資や雇用、政治的選好への影響は限定的。削減コストは社会的炭素コストを下回り、他の気候政策より効率的。地域ベースのグリーン政策は投資誘導に有効だが、広範な経済・政治効果は限定的と示唆。
English
This study evaluates the impact of the Inflation Reduction Act's 'Energy Community' provisions on clean energy investment in fossil-fuel-dependent regions. Using spatially granular data, it finds substantial increases in local solar investment, but no significant effects on wind investment, job creation, or political preferences. Estimated abatement costs are below the social cost of carbon and lower than other major U.S. climate policies. The results suggest place-based green industrial policies can effectively direct investment to disadvantaged regions, but broader economic or political benefits may be limited.

日本のGX文脈において
日本のGX政策（例：脱炭素投資促進策）において、地域ベースのインセンティブ設計の有効性を示す示唆を提供。特に、化石燃料依存地域の公正な移行（just transition）を目指す政策立案に参考となる。
In the global GX context
This paper provides rigorous empirical evidence on the effectiveness of place-based green industrial policies, relevant to global discussions on just transition and industrial policy design. It informs policymakers in the EU, US, and elsewhere on the trade-offs between targeted incentives and broader economic impacts.

📄 Abstract（原文）
Governments across the globe are turning to place-based industrial policies to make the green transition more equitable and politically palatable. The United States' Inflation Reduction Act exemplifies this approach through its "Energy Community" provisions, which offer additional tax incentives for clean energy projects in regions reliant on fossil fuels. We use spatially granular data on renewable energy investment, employment, and voting, and document that these incentives substantially increased local solar investment, but we do not find significant impacts on wind investment, job creation, or political preferences. Estimated abatement costs are well below the social cost of carbon and lower than those of other major U.S. climate policies. The results suggest that place-based green industrial policies can effectively direct clean energy investment toward disadvantaged regions, but their capacity to generate broader local economic or political benefits may be limited.
