“小田并大田”模式是中国应对农地细碎化、推动农业现代化的重要实践。其推行的必要性缘于农地细碎化已严重制约农业规模经营、生产绩效与绿色发展，构成改革的现实压力；可行性则在于农户整合意愿增强、土地确权奠定权属基础、多元政策提供制度保障，共同为改革实施创造了有利条件。实践表明，该模式通过针对性举措有效破解了农地细碎化治理的资源、组织和实施困境，取得了农地集中连片和规模化经营、农业节本增效、耕地面积增加以及乡村治理能力提升的多重效果。机制分析表明，规划引导、社会化服务支撑、集体统筹和资源整合是其有效运行的核心机制。由此，可采取项目结合路径、新型经营主体引领路径和互换并地路径等推进“小田并大田”，治理农地细碎化。

The “Small Plots Merging into Larger Fields” model is a crucial practice in China for addressing farmland fragmentation and advancing agricultural modernization. The necessity for its implementation stems from the fact that farmland fragmentation has severely constrained large-scale agricultural operation, production efficiency and green development, thus posing practical pressures for reform. Its feasibility lies in three key factors: the growing willingness of farmers to engage in land consolidation, the solid property right established by rural land certification, and the institutional guarantees provided by diversified policies, all of which jointly create favorable conditions for the execution of the reform. Practice shows that this model effectively resolves the resource, organizational, and implementation challenges in tackling farmland fragmentation through targeted measures, achieving multiple outcomes including the concentration and contiguousness of farmland for scaled operations, reduction of agricultural cost, improvement of efficiency, increase of arable land area, and improvement of rural governance capacity. Mechanism analysis reveals that planning guidance, socialized service support, collective coordination and resource integration are the core drive forces for its effective operation. Consequently, pathways such as project integration, new-type agricultural business entity leadership, and land exchange and consolidation can be adopted to advance “Small Plots Merging into Larger Plots” initiative and address farmland fragmentation.
