The third phase of land reform, along with government modernization and modernization policies in agriculture, included three parts: establishing agricultural joint stock companies, selling leases, and encouraging agro-industrial capitalism. The reduction of agricultural products after the first and second phases of land reform forced the government to take action and compensate with government capital and the use of mechanized methods to reduce agricultural production. One of the new methods of agriculture, the laws and regulations of which were passed in 1967, was the establishment of agricultural joint stock companies. The first agricultural joint stock company (Aria Mehr Company) was established in Fars in 1968 and after that 14 other companies were established in Fars. Most of these companies were built around Shiraz, Marvdasht and Firozabad. In this research, we try to study how the establishment and performance of Fars agricultural joint stock companies and the social and economic consequences of these companies. The method of this research is descriptive-analytical based on historical documents and sources. According to the research findings, the government, by creating agricultural joint stock companies, apart from the economic goals that were included in the establishment of these companies, established these companies in a special area and closed the passage of part of the tribes, by announcing the area of the joint stock company. Agriculture led to the forced settlement of tribes and nomads within these companies. On the other hand, these companies, using more mechanized methods, made the farmers unemployed, and this led to the migration of more villagers to the city.
