Policy evaluation and mechanism design on farmland transactions

我们发现，日本农民仍然持有传统的偏好“ie”和社区，这可能会阻碍农田集中。另一方面，有一部分农户对通过交换地块来整合分散的地块持积极态度。农田改良项目刺激了核心机械作业的外包，但没有刺激购买或租赁农田。基于模拟分析，我们发现，通过自愿地块交换无法解决农田碎片化问题。然而，集中的集体交换可以实现近乎完美的农地整理。

We found that Japanese farmers still hold traditional preferences on “ie” and community, which may hinder the concentration of farmland. On the other hand, certain fraction of farmers is positive in exchanging plots to consolidate fragmented plots.Farmland Improvement Projects stimulated outsourcing of core machinery works but not purchase or rental of farmland.Based on a simulation analyses, we found that farmland fragmentation cannot be resolved through voluntary plot-exchange. However, a centralized, collective exchange can achieve nearly perfect farmland consolidation.
