Measuring Productive Efficiency in Multiple Product Agribusiness Firms: A Dual Approach
使用前沿多产品成本函数测量零售化肥厂的生产效率，发现平均工厂可通过更有效的运营降低10%的可变成本，且配置效率低下程度很小，建议管理者专注于提高技术效率。
Abstract Measuring retail fertilizer plant efficiency is difficult, given the range of outputs produced by these multiple product firms. A frontier multiproduct cost function was employed to measure productive efficiency. Results suggest the average plant could lower variable costs by 10% through more effective operations. Allocative inefficiency was minimal, indicating management should focus on improving technical efficiency. The limitations of employing a single‐product model in a multiproduct situation are demonstrated.
