Investigation of Efficiency Alternations and Technological in Olive Industry in Iran Print

Olive is one of the oldest plants in the world. With attention to ecological conditions of Iran for cultivation of olive and also importing of 80 percent our needed olive oil. The development design of olive groves in Iran started at 1993.This paper examines the performance of the Olive industry in Iran over 1985–2009 years. Malemquist index approach permits fully non-parametric estimation avoiding the usual curse of dimensionality that plagues traditional non-parametric efficiency estimators. The resulting estimates are robust with respect to outliers and noise in the data. The results of study show that following the removal of government intervention policy in olive industry and distribution, efficiency in all provinces improves for 1985-1993. For 1993-2001, jumping in technological progress with the average annual rate of 9.8 percent is remarkable.
