Abstract :

The purpose of this study was to estimate technical efficiency of cucumber greenhouses in Eastern Azarbayjan. In economic literature, it means the ratio of maximum output to the inputs. The objective of this research was to determinate the effective factors influencing it's inefficiency. The method of determination of deterministic and stochastic technical efficiency is corrected ordinary least squares (COLS) and maximum likelihood (ML) respectively. The average of technical efficiency in province’s cucumber greenhouse is approximately about 57 and 93 percent for deterministic and stochastic frontier method respectively. Production types had positive influence on technical inefficiency whereas experience of manager have negative influence on technical inefficiency.
