For a long time, East pivot of metropolis Tehran has been playing an efficient role in spatial urban and rural habitation development in its region; so that in different periods this capacity and potential caused the pivot develop rural and urban habitations without meeting planning rules and requisites. Lack of schedule, and scattered, however, created disorganization and unfavorable conditions from different economic, social, environmental, and demographic aspects. Accordingly, the government has taken decentralization in Tehran into account  based on new cities experiences in other countries and in order to decrease the population load, and also constructed and developed Pardis new town to organize habitation on this pivot in order for eliminating regional unfavorable conditions around Tehran. After more than two decades of Pardis new town construction, however, failure and success of this policy has received attention. Hence, this research serves to consider and comparatively analyze east pivot of Paris (as a successful instance of European new cities) and the one of Tehran. Research methodology is comparatively analyzing these two instances by means of spatial cartographic analyzes and comparative comparison of data related to spatial and skeletal characteristics of studied areas. perceived results indicate that planning without considering spatial relations between activities and habitation and a simple point attitude towards habitation are of main causes of failure in management and equalizing eastern region of metropolis Tehran. That is, new town Marne-La-Vallee in east of Paris comprises all houses and even old rural centers on its base beside spatial capacities of new development, whereas only determining the range of development and new buildings are considered regardless of habitations interrelations between Roudehen, Bumehen and Jajrud, and relations between other existing habitations in this pivot or spatial order has been neglected.
