Quantifying Economic Benefits of Sow‐Herd Management Information Systems Using Panel Data
结合两项调查数据，通过面板分析估计母猪场采用管理信息系统后每头母猪每年多产0.56头仔猪，投资回报率在220%到348%之间。
Abstract Economic benefits of management information systems (MIS) in sow farming were quantified by combining data from two survey studies. Panel analysis was conducted through estimation of a mixed‐effects model by ordinary least‐squares. Effects were analyzed both within farms and over farms at the same time, controlling for self‐selection bias and changes over time. Adjusted for other effects in the model, production on farms adopting MIS increased by 0.56 piglets per sow per year, indicating a return on investment of between 220% and 348%. Additional tests and checks indicate that this outcome is robust.
