Abstract :

Today all countries are seeking to achieve high productivity. This means that they can achieve more production with fewer resources. Productivity has an important and effective role in increasing production and growth in sectors of economy. Through calculating and analyzing the indicators of productivity the efficiency of various economic sectors can be reviewed. In this study with a Solow residual and lag model, total factor productivity growth in agricultural production during the period 1387 - 1358 were calculated. For this purpose, the Agriculture crop sector production function with capital, labor and energy was estimated using the ARDL approach. Then, using the index of Solow, TFP growth in agriculture crop sector was calculated. The results showed that total factor productivity growth in agriculture crop sector had experienced periods of high volatility. So that the average period of 0.8 percent. The mean total factor productivity growth in crop sector of agriculture , with the figure predicted in the fourth program (2.2) are of significant difference. It is suggested that the cycle of productivity policy should be done, to increase TFP in this sub-sector of agriculture.
