Abstract: Prices are one of the parameters of economic availability of goods and services. Large interregional differences in the price of any product lead to inequality in its availability in some regions and pose a threat to socio-political stability. Therefore, the study of regional prices for basic socially significant goods is a relevant area of economic research. The subject of our study is the phenomenon of spatial heterogeneity in the availability of food products in the Russian Federation, due to price differences. The purpose of the paper is to find patterns in regional price differentiation for the most popular product of the fish group - frozen whole fish and its substitute - beef. Both products are included in the list of basic food products, for which the Doctrine of Food Security of the Russian Federation sets threshold values for food independence, economic and physical availability. The paper analyzes data on the spatial distribution of prices for these goods, determines the main static and dynamic characteristics of price heterogeneity, and identifies key factors that can potentially lead to the emergence of disparity in regional prices. The main results of the work were the identification of a hidden trend of growth of interregional differences in fish prices in the Russian Federation, structuring of regions by price level, and detection of a number of patterns and anomalies in spatial differentiation of fish prices. The methodological basis of the work is statistical analysis tools, which are selected and adapted in accordance with the purpose of the study. The information base is data from publicly available sources.
