Rice is one of the most important agricultural products, and improving productivity of its factors is a prerequisite for increasing its production growth. The objective of this research is to decompose total factor productivity growth of rice production in Iran. The required data for the period of 2000-2020 were collected from the Ministry of Agricultural Jihad and the Statistics Center of Iran. The rice productivity growth and its components, including scale and technological changes, were evaluated applying parametric (stochastic frontier analysis) approaches. Based on estimated translog cost function, the annual growth of the total factor productivity was calculated to be 2.1% and technological change was realized to be positive in the country throughout the years and the most of these changes are due to the improvement of the technologies used. Since the technological change has made a significant contribution to improving the total factor productivity growth in this approaches, utilizing, improved seeds, modern machines, fertilizers and nutritional solutions, etc. are recommended in the process of rice production. Therefore, the results obtained have sufficient confidence and it is suggested to use parametric approaches as much as possible in future studies.
