本研究利用 2010 年、2012 年、2014 年和 2016 年越南河西省和义安省两个省份 618 个农户的面板数据评估了土地整理对家庭农业生产的影响。我们采用双重差分法来解决家庭参与地块交换的内生性问题——这是一项巩固越南分散农田的政策。我们的方法与以前的研究不同，以前的研究通常使用家庭的地块数量，而很少处理内生性问题。我们的结果表明，地块交换使家庭经营的一年生作物地块数量减少了近 50%。这种土地整理随后改善了农业灌溉和机械的应用。虽然对农业生产力的影响在统计上微不足道，但通过地块交换进行的土地整合减少了农作物生产的农业劳动力供应。因此，土地整理可以释放农场劳动力，刺激非农农村经济。
This study evaluates the impacts of land consolidation on household farm production with panel data on 618 rural households in 2010, 2012, 2014, and 2016 in two provinces of Vietnam: Ha Tay and Nghe An. We apply a difference-in-differences approach to address the endogeneity in household participation in plot exchange – a policy for consolidating fragmented cropland in Vietnam. Our approach differs from those of previous studies that typically use a household’s number of plots with little treatment of the endogeneity problem. Our results show that plot exchange reduced the number of annual crop plots operated by a household by nearly 50 percent. This land consolidation subsequently improved farm irrigation and the application of machinery. While the impact on farm productivity was statistically insignificant, land consolidation via plot exchange reduced farm labor supply for crop production. Thus, land consolidation could release labor from farms and stimulate an off-farm rural economy.
