As a result of the evolution of approaches from government to management, today the participation of the private sector in organizing disordered structures is one of the principles of planning in these areas. The study of the role of economic elites in the promotion of Isar neighborhood (the declining area of ​​Mashhad) is the main subject of this study. In terms of type, this research is descriptive-analytical and in terms of method, it is causal. In addition to field data and official censuses, in this study, 97 questionnaires were distributed among the managers of Isar Bazaar stores and 53% were answered. Spatial and non-spatial relationships were tested by general and spatial regression. In addition to increasing the population by one percent, the most changes are in both residential and commercial uses, and the creation of 20 educational uses, 11 religious uses and 6 health-medical uses are other changes. 65% of employees work in the service sector. Between 2001 and 2015, 52616 square meters of commercial use and 99596 square meters of residential use were added in this neighborhood. In this regard, the members of the growth machine have succeeded in increasing the value of their real estate and assets by investing in change of uses. Regression between the explanatory variables and population growth in the neighborhood, as a result of the participatory action of production-commercial elites in the development of Isar neighborhood shows that the variable of commercial use area with a coefficient of 54% has the highest explanatory rate among the variables. The development of the neighborhood is the result of the participation of the private sector and the management and control of land use change by Mashhad Municipality as a local government, a partnership that is not based on bureaucratic system, but on entrepreneurship, market economy and local community network communication. Given the role and role of the public and private sectors, the neighborhood in question is an example of real participation, in the Einstein model is at the top with the power of citizens.
