One of the important strategies that have been taken into consideration in the last half-century to counter regional imbalances, caused by the increasing growth of large cities, is the creation of small cities. Due to the availability of some facilities and services, small cities are considered as one of the important centers for bringing balance to regional development. The method of the present research is a descriptive-analytical one, and the purpose of this research is to study the status of changes in the urban system of the small cities of Alborz province in order to bring balance to the regional sustainable development. In order to find out the status of small cities in the urban system in a 30-year period (1986-2016), rank-size models, as well as entropy and balance sheets models were used, and then their role in bringing balance to the regional development was evaluated. The results of the study show that the Entropy coefficient without counting the small towns, will still have imbalances. The rank-size logarithmic model, by counting small cities with the slope of the line amounting to -1.94 and without counting small cities reduced to -1.21, indicating the undeniable role of small cities in the urban system. Also, the results of the balance sheet model show that component changes are mainly intra-class and are due to the growth of cities. Moreover, concerning the process of changing villages to cities, changes resulted from the formation of new cities can be seen only in 2006.
