The Effect of Land Fragmentation on the Technical Inefficiency of Dairy Farms
利用爱尔兰奶牛场的详细数据，研究发现土地碎片化（地块数量多、距离远、分散）会显著增加技术效率损失，而扩大地块面积、减少运输距离、增加咨询服务和雇佣劳动可缓解这一问题。
Abstract 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.
