We estimated the regional Farrell 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 well 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 small, 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. © 2006, JAPAN SECTION OF THE REGIONAL SCIENCE ASSOCIATION INTERNATIONAL.
