A Generalized Measure of Farm‐Specific Technical Efficiency
利用菲律宾中央吕宋地区22个水稻农场的面板数据，通过随机前沿生产函数残差计算农场随时间变化的技术效率，发现效率范围在84%到95%之间，表明通过资源再分配提高产出的空间有限。
Abstract Single measures of farm‐specific technical efficiency over time are calculated for rice farms in Central Luzon, the Philippines, from the residuals of a stochastic frontier production function. Panel data from the International Rice Research Institute's periodic “Loop Survey” are used. Results show a narrow range of efficiency between 84% and 95% across the twenty‐two farms, so that there is limited scope for increasing output by resource reallocation. A comparison is made with measures of technical efficiency using traditional covariance analysis.
