Many scholars believe that the city is a social innovation whose size, location, and internal organization are in terms of "power"; And many changes in the structure and role-playing of the city are due to the mobility of "citizens". The shape and appearance of the city, like the country, represents the pressure from the bottom up. Therefore, urban space processes have very low effects on the whole of politics, especially political development Competitiveness is one of the important issues that has been emphasized in urban literature in recent years and in this regard, different perspectives on the determinants of competitiveness have been presented. As a geographical phenomenon, the city has an effective role in power games and constitutes the most important spatial level of stress, action and competition in the present age. The present fundamental research with descriptive-analytical method express the fact that the necessary fields for their geopolitical study have been provided by creating a competitive environment and promoting the domestic and international competitiveness level of metropolises. Hence, an urban-scale geopolitics has made cities important actors in different geographical areas. The results of this study show that there is a relationship between the effectiveness of the roles of a place and the geographical area with its "power". That is, as the roles have more extensive and in other words the broader function, the power of geographic location increases, like global cities. Indeed, the phenomenon of the city is studied and investigated in various dimensions, with emphasis on the central elements of politics, power and competition.

Sunlight illuminates only 20 to 25 percent of the home space. Villagers usually thicken the walls to withstand the temperature (heat and cold). Also, it was shown that the average diameter of dry walls is between 100 and 75 cm. The results showed that 89% of the first-floor residential units are wet and damp.
