Ranking Urban Areas for Distribution of Service Uses by PSI Method and Analyzing its Relationship with Municipal Revenue from Spatial Justice Perspective (Case Study: Arak)

Although urban planning researchers emphasize that the distribution of benefits from the implementation of urban policies should be distributed fairly, in some cases not only some areas of the city do not receive a fair share, but also spend the income of each region relative to its income. The area is disproportionate.The purpose of this study is to analyze the spatial distribution of public uses in the five districts of Arak to determine the relationship between the distribution of service uses and the municipality's revenue earned from construction crimes in each area. The research method is descriptive and correlational. The PSI technique was used to rank, the Kendall tau-c coefficient and gamma coefficient were used to determine the correlation. data are obtained from GIS data and library method. According to findings There is no spatial justice in the distribution of urban services in the five districts of Arak. District1are in the best condition and District5are in the worst condition. The relationship between the rank of regions in terms of per capita public uses with the revenues earned from construction violations in each region is -0.4,which is a significant, inverse and moderate intensity relationship.Therefore, the municipality must prevent construction violations; Then, as the most important institution in planning and implementing policies for providing and distributing resources of wealth and opportunity in society, to provide public services in each region in proportion to the income earned by the residents of that region, to provide services in each region. It is suggested that the laws be amended so that the budget allocation of the municipalities in the region is commensurate with their income. In this regard, it is necessary to change the laws to allow local governments to spend some of the revenues of the regions in proportion to the service deficit.
