Imports and the current structure of the world economy play an important role in developing countries growth strategies. Therefore, any change in Iran's imports will affect the production and growth. Hence, the investigation of different aspects of imports in relation to development requirements of the country is essential for policy purposes. In this article the long run pattern of import demands from major trading partners is investigated using almost ideal demand system model (AIDS) and seemingly unrelated regressions.
The results indicate that Iranian long run import allocation is formed in one stage budgeting and depends on domestic sales. Homothetic and symmetry hypotheses are rejected. The imports from five major trading partners are necessary goods.
Uncompensated down price elasticities of United Arab Emirates, Korea and France have the negative anticipated signs and imports from Germany and France have a complementary relation. Imports from Korea are strongly affected by import prices.
