Polycentric advocates that spatial pattern can create a balance between conflicting goals of economic competitiveness, social cohesion, and environmental sustainability on a large-scale. So far, many studies have looked at the effectiveness and efficiency of hypotheses raised to polycentric structures, but few studies have considered the relationship between land prices and affordable housing. In this regard, first, the provinces of the country were measured with two indicators of spatial and city size distribution. Then, using a bivariate regression, their relationship with land price indexes, land price growth and affordability of housing were investigated. Research findings support polycentric spatial patterns. So there is a positive and significant relationship between the spatial distribution of cities and the distribution of cities and land prices. Also, the balanced distribution of urban centers in the territory of the land could partly control the growth of housing prices. In addition, there is a relatively strong and significant relationship between polycentric and affordable housing indices. Consequently, polycentric structures seem to be more resilient in higher housing prices at peak times.
