ERAE | Chang & Lin：农田分区是否影响农业收入：来自台湾农户的经验证据

摘要：农田分区会影响农业收入吗？为什么？本研究以台湾个案研究来探讨这些问题。我们使用一个独特的农田水平数据集，并应用不连续回归来量化分区对农业收入的影响。我们发现分区计划降低了农业收入。但该计划对不同农业主体影响不同，在农业收入分配中占比较高的农场效果更明显。此外，对年纪较大的农场经营者的影响更大。在机制分析中，我们认为分区计划为符合条件的农场产生了利益选择或财富效应。这种财富效应会将家庭劳动重新分配到非农工作中。因此，分区计划减少了农业收入。

Abstract: Does farmland zoning affect farm income, and why? This study addresses these questions using a case study in Taiwan. We use a unique farmland-level dataset and apply the regression discontinuity design to quantify the effects of zoning on farm income. We find that the zoning program decreases farm income. The programme effects are heterogeneous, as they are more pronounced for farms in the higher percentiles of the farm income distribution. Moreover, a larger effect is found for elderly farm operators. Concerning the mechanism, we argue that the zoning program generated an optional benefit or wealth effect for eligible farms. This wealth effect then reallocates family labour to off-farm jobs. Consequently, the zoning program reduces income from farming.
