中国30省のパネルデータ（2011-2023年）を用い、新たな農業経営主体の発展が農業炭素排出の限界削減費用を有意に低下させることを実証。農民合作社や家族農場が特に重要で、信用制約の緩和、土地配分効率の改善、技術進歩が経路。空間的波及効果も確認。

English

Using panel data from 30 Chinese provinces (2011-2023), this study shows that the development of new agricultural business entities significantly reduces the marginal abatement cost of agricultural carbon emissions. Farmer cooperatives and family farms are particularly effective, with mechanisms including eased credit constraints, improved land allocation, and technological progress. Spatial spillover effects are also significant.

日本のGX文脈において

日本の農業分野では、みどりの食料システム戦略やカーボンニュートラル目標に関連し、農業経営体の規模拡大と脱炭素の経済性を結びつける示唆を提供。日本の農業構造（小規模経営が多い）に当てはめる際には、経営主体の類型や支援策の違いを考慮する必要がある。

In the global GX context

This paper contributes to the global literature on agricultural decarbonization by quantifying the cost-effectiveness of institutional innovations (new business entities) in reducing abatement costs. It offers insights for developing countries seeking low-carbon agricultural transformation, complementing technology-focused studies with an economic-organizational perspective.

📄 Abstract（原文）

Introduction The development of new agricultural business entities has become an important driver of agricultural modernization and rural transformation. Their growing role in promoting green agricultural development and carbon mitigation highlights the need to assess not only their emission-reduction potential but also the economic costs of carbon mitigation. However, whether these entities can reduce the marginal abatement cost of agricultural carbon emissions remains unclear. Methods Using panel data from 30 provinces in China from 2011 to 2023, this study empirically examines the impact of new agricultural business entities on the marginal abatement cost of agricultural carbon emissions and its underlying mechanisms by employing a two-way fixed effects model, mediation analysis, and spatial econometric models. Results The results show that the development of new agricultural business entities significantly reduces the marginal abatement cost of agricultural carbon emissions. Further analysis indicates that farmer cooperatives and family farms play a particularly important role in reducing carbon abatement costs, with stronger effects in major grain-producing regions and areas with greater governance capacity. Mechanism tests suggest that new agricultural business entities reduce marginal abatement costs by easing agricultural credit constraints, improving land allocation efficiency, and promoting agricultural technological progress. In addition, the spatial econometric results reveal significant spatial spillover effects, indicating that the development of new agricultural business entities in neighboring regions also contributes to lower local agricultural carbon abatement costs. Discussion These findings provide new evidence on the economic mechanisms through which new agricultural business entities contribute to agricultural carbon mitigation and offer policy implications for promoting the low-carbon transformation of agriculture in China and other developing countries.
