提高农业生产力是快速增长的经济体面临的一项紧迫挑战。核心农户的农田集中有助于实现规模经济。然而，农田分割往往成为这种结构调整的障碍。本文研究了日本的农田改良项目，该项目通过合并和扩大小块土地以及整合农民之间的地块，从物理上缓解了农田碎片化。我采用社区层面的面板数据，利用差异中的差异匹配估计，以衡量项目的影响。我发现这些项目以机械工作外包的形式对结构调整产生了积极影响。
Improving agricultural productivity is a pressing challenge for rapidly growing economies. Farmland concentration among core famers is instrumental for reaping the economies of scale. However, farmland fragmentation often serves as a barrier to such structural adjustments. This paper studies Farmland Improvement Projects in Japan, which physically mitigate farmland fragmentation by merging and enlarging small plots and consolidating land parcels among farmers. I employ community-level panel data to make use of difference-in-differences matching estimators, in order to measure the projects’ impacts. I find positive effects of the projects on structural adjustment, in the form of machinery-work outsourcing.
