《AAERS》| Takayama et al：DP政策覆盖地区报酬、耕地弃置和农场规模：来自日本丘陵和山区的证据

摘要：自2000年以来，日本已经实施了一项针对丘陵和山区的直接支付(DP)计划。该计划的目标是缩小这些农业生产不太有利的地区和其他地区之间的生产成本差距，防止弃耕地增加。符合条件的农村社区决定是否接受DP计划援助，该计划拨款的一半用于社区协作活动，其余一半直接分配给农民。我们采用双重差分模型（DID）来检验这些支付对耕地使用的影响。使用补贴开始前后大型农场的面板数据，我们采用一个处理组和两个对照组构建了一个因果分析框架。我们发现，补贴导致了幸存农场弃耕地增加的放缓。此外，补贴对幸存农民经营农场的规模存在边际递增效应。结果表明，在该政策覆盖地区，直接支付计划在保持耕地方面起着关键作用。

Abstract: A direct payment (DP) scheme for hilly and mountfainous areas has been in place in Japan since 2000. This scheme’s objective is to fill the gap in production costs between these less favourable areas and other agricultural locations and prevent abandoned farmland from increasing. Eligible rural communities decide whether to receive DPs, and half of the DP allocation in communities with DPs is distributed for collaborative community activities, with the remaining half allocated directly to farmers. We apply a difference-in-differences approach to examine the effect of these payments on farmland use. Using a large farm-level panel data set from before and after the payments were initiated, we employ a causal framework of analysis with a treatment group and two alternative control groups. We find that the payments led to a slowdown in the increase of abandoned farmland among surviving farms. Moreover, the payments have a marginal positive effect on the operated farm size of surviving farmers. The results imply that direct payment schemes in less-favoured areas play a key role in maintaining farmland.
