Abstract

This study was conducted with the aim of measuring the productivity index of all factors of production in agriculture and identifying the structures affecting it in 20 provinces of the country. In the first step, the productivity index of all factors of production under the agricultural sector in each of the studied provinces was measured and analyzed using the non-parametric approach of Malmquist productivity index hidden in data envelopment analysis (DEA-MQI) and data of crop years 1387 to 1397. In the second step, using the system of apparently unrelated regression equations (SURE), the factors affecting the increase in productivity index of all of production of the agricultural sub-sector of the studied provinces were estimated.Based on the research findings, the total factor productivity index of agricultural production sub-sector of Qazvin and Ilam provinces has the highest and lowest average factor productivity index, respectively. development of agricultural conversion and processing industries, extension training of farmers, crop insurance and intensity of mechanization have a positive and increasing effect on total productivity of agricultural sub-sectors.
