Thailand is currently the world’s largest natural rubber producer. The country also has a strong of rubber production that represents a significant portion of the Thai economy and intensive labor force. Thailand has experienced a development of policies oriented to improving the rubber production. These policies have been implemented throughout the country, particularly at the Southern region. The purpose of this study is to measure the technical efficiency of rubber production of 14 cities, located in Southern Thailand by using a three–stage data envelopment analysis (DEA) model that was studied to remove environmental factors. Moreover, Malmquist productivity index (MPI) was used to measure the changes of rubber production efficiency and estimates of the rubber productivity trend from 2010 to 2012. Based on the estimated results of the proposed panel model with the adjusted inputs, in general it can be concluded that the rubber production in Southern Thailand had good performance efficiency improvement, technical progress, and productivity growth in 2012. The
III
Malmquist DEA model shows that for the rubber production, the productivity indicators including efficiency and technical change and productivity growth are in general showed a declining trend from 2010 to 2012. The study, however, found that the environmental factor was still a significant variable to explain technical efficiency in Southern Thailand.
