The government system of' Iran is centralized, and because in unitary and single power states, the security of political center (capital) with the total security of political system (National Security) has a direct relationship, the capital movement in Iran becomes important from two aspects; the first is to organize Tehran city and balance urban and regional system of the country and the second is to maintain the political security of the country. Capital movement from Tehran to other cities has been among the issues for more than 220 years but nothing has been done for some reasons. The aim of this paper which is written by descriptive – analyzing and survey method is to identify the main obstacles and the challenges of processing the capital and to present the strategies to remove the obstacles. So 7 elements as Economic, political, security, executive, social-cultural, legal and natural-ecological elements are selected in 55 items and are weighed by the academic elite people. After analyzing the information and using the structural equations model the results showed that the legal factor holding 10 items has the most direct (0/089) and indirect effect and the natural-ecological factor has the least effect (0/033) in moving the capital. Also the results of the network analyzing model for preference survey showed that the experts give priority to executive obstacles which hold final weigh 0/218 and compatibility rate 0/022 stands at the first grade in the priority survey of the obstacles.
