As a result of the pandemic, both the internal needs of the territory (country, region) and the importance of providing humanitarian assistance to the countries with food shortages may grow significantly. The food security assessment and the application of measures to improve it, should be carried out in advance. The reorientation of import substitution policy to export-oriented one should also be based on the competition development in the industry. In the article, the authors suggest to calculate a new type of Herfindahl-Hirschman index, which characterizes the level of producers’ concentration at the market by the share of gross profit of economic entities. The research purpose is to provide scientific justification of practical recommendations for the development of food markets in the region, taking into account the level of their concentration. Based on multidimensional statistical calculations, the authors analyze the hypothesis of a positive impact of large economic entities (including monopolies) development on the provision of local food products to the population; consider tools for forming the vector of industrial and competitive policy based on matrix positioning, as well as conduct correlation and regression analysis on the example of the regional beef market.
