Exploiting the link between land identification and farm accountancy data, we use a uniquely detailed database to conduct a robust analysis of land fragmentation and its effect on technical inefficiency on dairy farms in Ireland. Using a stochastic production frontier model, our results show that the number of parcels, the average distance between parcels and the main farm, and the portion of land separate from the main farm all increase technical inefficiency. Such inefficiency can be reduced through increased parcel area, reduced travel distances, advisory services contact, intensive practices and hired labour. Our findings support the need for policy to improve land and labour mobility, providing evidence to support incentives to promote the transfer and long‐term leasing of agricultural land.

土地分割对奶牛场技术效率低下的影响

利用土地标识和农场会计数据之间的联系，我们使用独特而详细的数据库对土地分割及其对爱尔兰奶牛场技术效率低下的影响进行了有力的分析。使用随机生产边界模型，我们的结果表明，包裹的数量，包裹与主要农场之间的平均距离以及与主要农场分开的土地部分都增加了技术效率。可以通过增加包裹面积，减少旅行距离，咨询服务联系，集约化做法和雇用人工来减少这种效率低下的情况。我们的发现支持制定政策以改善土地和劳动力的流动性，并提供证据支持鼓励促进农业土地转让和长期租赁的激励措施。
