One of the principles of sustainable urban development is equal access of all citizens to the required services. Basically this matter comes true when different urban lands and resources, equally allocate to the spatial and social units of the city.Sincecommercial and service land uses are used by city dwellers daily, their locating and spatial distribution in cities is very important. Proper distribution of chain stores plays a significant role in reducing transpotation costs, quick supply of goods and services, suitable access to parking and other urban supplementary services. A chain store consists of several co-owned and centralized retail stores. The purpose of this study is improvement on spatial distribution of chain stores in Tabriz. To this end, first, the indicators of chain stores locating identified through available resources and documents and then through quantitative and spatial analysis methods using GIS capabilities, distribution of chain stores in urban areas of Tabriz was studied. Six criteria including population, type of communication, centrality, compatible uses, local equilibrium and radius of access have been used for a comprehensive analysis. After preparing the layers related to the above parameters using analytical tools in Arc Map software, they were integrated and the final layer was extracted. The results show that the distribution pattern of chain stores in Tabriz is random and it doesn't have a specific pattern. Also, the location criteria for the current stores have not been met in a desirable manner.
