The subject of the study is the uneven development of the primary and service sectors of the economy in the microdistricts of Ryazan as a factor of intra-urban social inequality. It analyzes the spatial segregation of economic functions inherited from Soviet zoning, where industrial areas are separated from residential and commercial zones. Special attention is paid to the break in multiplicative connections between sectors: developed industrial clusters do not stimulate the local service sector, creating a transportation-trade dichotomy between the center and the periphery. A three-level structure of inequality is identified – transport compensation for the lack of services in the outskirts, premium business infrastructure in the center, and the absence of basic amenities in the periphery, forcing the population to travel to central areas. The study synthesizes the concepts of micro-realism by P.B. Struve and soft zoning to explain the atomic nature of the disparities. The methodological approach included sequential stages: initial normalization of indicators (30) on normalizers to eliminate the scale effect, secondary standardization with z-scores, principal component analysis by sectors to form localization coefficients for the primary and service sectors, calculation of the difference between them, and the global Moran index to assess the spatial distribution of resources. The scientific novelty lies in the empirical confirmation of Struve's micro-realism concerning intra-urban inequality: a negative correlation of r = -0.613 between the primary and service sectors quantitatively proves the break in multipliers in post-Soviet cities. The zero global Moran index (I = -0.022) establishes the atomic nature of development – 62 microdistricts function as isolated economic organisms without the neighborhood effect. The architecture of inequality in Ryazan represents a complex system, where transportation accessibility partially compensates for the lack of services in the periphery, but does not restore the disrupted multipliers. Central areas with ultra-high specialization in the service sector (successful diversification) contrast with industrial zones, which require targeted measures of soft zoning – tax incentives for trade in industrial clusters and infrastructure standards for the depressed periphery.
