  • 摘要:In this study, estimating the production function and calculating technical efficiency of wheat producers of Darreh Shahr, where the required data were collected from 90 exploiters in the crop year 2014-2015 through questionnaire, were carried out. For this purpose, at first, Cobb-Douglas production function was chosen by econometric tests, and then technical efficiency was measured using stochastic frontier analysis (SFA). The results of this study showed that the technical efficiency of farms is in the range of 0.61 to 0.98 and technical performance average is 0.89. Investigating inefficiency model showed that experience, education and number of pieces of land have had negative effects on the technical inefficiency of exploiters and farmer's age and insuring the product have had positive effects on technical inefficiency of manufacturers
