Urban space is created in the balance of performance and urban components, positioning them optimally suited to their needs. To specify the parts of the city, techniques must be used to determine the best spatial organization was formed. Among these techniques, the Space Syntax. This study examined the interaction of the user space and the urban network link to achieve suitable spatial structure has been conducted. How to create spatial balance in Shiraz, in the context of the production and absorption of urban trips model Space Syntax is also the main research topics, And to determine the spatial and location are two important factors interact municipal, urban spatial balance has been put to the test. The purpose of this paper is to investigate the spatial structure of the city and the role of physical factors - Performance in shaping the structure.Analytical method - documentary that combines models and using the theory of gravity, the interaction between urban space is calculated, Then, using the technique of Space Syntax, the integrity of areas and then using linear regression to estimate the causal relationship between these factors, the equation is implemented. Sig = 0.493 indicates a correlation between actions to achieve integration of spatial and urban areas, and its impact on spatial balance in Shiraz. Among the areas of Shiraz Municipality, the difference between standard action with the margin of error in the 8th District 251, has a margin of error of 4 regional worst and 20 the best situation, in terms of spatial structural balance.The regression equation of activity and its spatial structure suggests that these two variables with R Square = 0.70, dependence than are good, the index shows that 70 percent of the dependent variable, independent variable arises. Data analysis showed that the physical structure of the city - urban spatial imbalance and the integrity of areas is very low. Shiraz space in urban areas and their integration and interaction between these two factors together suggest that, The result of this research shows, the correlation between location and interaction areas in the least amount of space or does not exist or is.
