The main purpose of this study is to measure and investigate factors affecting technical inefficiency of golden banana farms in Thailand under organic production system. In the first stage, to estimate efficiency scores, the data envelopment analysis (DEA) approach is applied to farm"=level cross"=sectional survey data of banana farms in two districts of a province in the Southern Region of Thailand. In the second stage, in order to examine the effect of farm"=specific socio"=economic and management factors on farm efficiency, a regression model is estimated where the level of inefficiency from DEA is expressed as a function of these factors. Then, Tobit estimation is used in this study. Previous studies have investigated technical efficiency and its components at both the farm and aggregate levels in Thai agriculture. However, this study, to the best of our knowledge, has been the first application of DEA in order to measure and explain technical efficiency and its components of banana farms in Thailand. The empirical results suggest two important findings. First, the technical efficiency scores of some farms were considerably low. Second, there is confirmation that farm size, producers' education and experience, and production system have influenced the technical inefficiency of banana farms while the differences in producers' age and the number of farm visits per year do not have different impacts on technical efficiency in Thai banana production in different farms. Therefore, the development policies of the above areas should be used to increase the technical efficiencies of these inefficient farms in Thailand.}
