我们估计了菲律宾水稻部门的区域Farrel技术效率指标和Malmquist全要素生产率指数，使用1971 - 1990年期间的一个产出四投入模型，结果表明，吕宋岛在这一时期的全要素生产率仅为轻微的正增长，吕宋岛的全要素生产率在这一时期经历了强劲的正增长，技术进步也在这一时期得到了显著的改善70年代后期的绿色革命时期，引进了第二代现代品种，虽然低效的变化很小，但在米沙鄢中部和东部等一些地区，低效的生产仍在继续。80年代后期的负增长表明产量的增长赶不上投入水平的增长。JEL分类：O 13、O33、Q16
We estimated the regional Farrel measure of technical efficiency and the Malmquist total factor productivity index of the Philippine rice sector.Using the one output four input model for the period during 1971 1990,the results showed that the total factor productivity was only slightly positive during this period.Luzon Island experienced strong positive growth of total factor productivity as wel as the technological change during the post Green Revolution era in the late 70s when the second generation modern varieties were introduced.Although the change in inefficiency was quite smal,the inefficient production continued in some regions such as Central and Eastern Visayas.The negative growth in the late 80s suggests that the growth of the output could not catch up with the growth of input levels.
