In 2009, urban renewal policies and widespread level of informing people have opened a new chapter in urban renewal programs in Iran. The impacts of these policies are very evident in Tehran city. Since October 2009 to November 2010, about 5 percent of the residents of old fabric in the whole country received 25 percent of the budget devoted to urban renewal programs and considerable improvements in rebuilding of the old fabric have occurred. The purpose of this research was to determine the impacts of the urban renewal incentive policies during the past 1.5 years. The results of research show that the number of building permits issued for the old fabric in Tehran city had 212 percent growth, compared with 133 percent for the whole city. Also, the amounts of floor areas built, the number of dwelling units built, the amount of residential land areas within the old fabric, compared with the other areas shows the positive impacts of incentive policies. The numbers of housing permits issued had considerable growths (about 22 percent growth). The old fabric consists of only 5 percent of the Tehran's total land area. The results of study show that whenever there is a stop in receiving the incentives, especially financial incentives, there is a reduction in the number applicants for housing permits. The number of housing permits in old fabric had higher growth compared with the whole city during the past 1.5 years while the incentives policies have been implemented. In February 2010, the number of housing permits issued for the whole city had 254 percent growth compared with November 2009 and 285 percent growth for the whole city. Also, growth in the number of dwelling units built during this period had 134 percent growth for the old fabric compared with 260 percent growth for outside the fabric. The high difference between the numbers of dwelling units built within the old fabric and outside is due to a stop in receiving the financial incentives by the residents in the old fabric.

In today's word which its complexity is increasing day by day, having enough acquaintance of different areas causes informed and functional intervention and enhancements. To identify development and the lack of it in different regions, we need to evaluate the zonal disparities pattern and the difference between the regions, and assess the superiority of a location in compare of structural-similar places in the city. The aim of the essay is to deploy the mechanism of equal opportunities, and to achieve the level of provincial inequalities in the country through the investigated indicators. The research method is "descriptive and analytical", which quantitative modals are used to determine the development degree of Iran's provinces. 34 urban development indicators have been chosen, and by using factor analysis these indicators have been studied, which have been classified in 4 significant factors, and the provincial rankings are based on these 4 items. Also by using cluster analysis homogeneous states are set alongside each other and have the same level. The provinces are classified in 3 homogeneous clusters, deprived (level 3) (under developed), average development (level 2) (among development), and extended (level 1) (high developed).

The aim of this paper is to analyze the hierarchical network of urban areas of West Azarbaijan for examining the rate of balance in variance and spatial distribution of population of urban areas in the province of West Azarbaijan. The methodology in use is a pragmatic-developing one. The quantitative models, such as bulk modulus, urban centralization index, anthropy model and gini coefficient index, are used in order to analyze the urban hierarchy of West Azarbaijan. Findings of this study shows that Urban centralization index in all the studied periods was higher that one. Population bulk modulus of all cities of the province in the years of 1956, 1966 and 1976 had augmented but in the years of 1986, 1996 and 2006 has reduced. Anthropy index in all the studied periods was less than one, which shows the unbalance in population in urban areas of the province. Calculation of spatial coefficient LQ shows that small cities of the province are exporter of services and their basic economy is based of services sector. The communicative network of the province, specially the roads, is in a condition that economically targets the capital of the province and like a radius ends to Urumieh. The final conclusion of this research is that the unbalance in variance and the spatial distribution of population in urban areas of the province is the characteristic of network of urban hierarchy of the province of West Azarbaijan; in a manner that transactions between the cities of the province are also affected by the political-administrative structure of the country as well.
