Improvement and development of different areas of a country is one of the main regional economic theories. It is important to analyze and investigate the process of production and structure in each area through identifying talents, balancing potentials, and combining components in each area so that authorities can have a basic plan for each region of the country. To this aim, employing the method of transfer, the contribution of advantageous sections from 2000 to 2013 was investigated. The findings show that most of the provinces had a positive regional and structural contribution in terms of agriculture, fishing, industry, building, hotel and restaurant, water, electricity, natural gas, wholesale, retailing, vehicle fixing, goods, transportation, storage, communication, health care, real state renting, and services. This reveals the comparative advantage of the regions in these areas. In the area of industry, there was a positive structural and competitive impact in provinces such as Isfahan, Ilam, Boushehr, Chaharmahal and Bakhtiari, Khouzestan, Semnan, Sistan and Balouchestan, Fars, Qom, Kermanshah, Golestan, Mazandaran, Hormozgan, and Yazd, which show the comparative industrial advantages of these regions. There was a decrease in comparative advantage so far as education is concerned in provinces such as eastern Azarbaijan, Isfahan, Ilam, Tehran, Chaharmahal and Bakhtiari, Semnan, Golestan, Koygeloye and Boyerahmad, Gilan, and Markazi, and in public services in provinces such as western Azarbaijan, Ilam, Tehran, and Semnan. However, as their economic contribution is significant, serious measures should be taken to deal with their malfunctioning.
