The purpose of the article is to determine the role of grain crop production in the social and economic development of Kostanay region in the context of integration. The production of grain in Kostanay region is able to provide enough food for the region and Kazakhstan as well. Also it is possible to export a number of agricultural and industrial products to EAEU countries. The increase in manufactured products and the organization of systems and services that ensure the most efficient functioning of all involved agricultural resources and infrastructure are especially relevant for increasing the competitiveness of grain products in Kazakhstan in modern conditions. Within this framework, Kostanay region has the potential strong enough to be competitive and participate in integration processes not only with the EAEU countries but also with other partner countries.The practical significance of the research lies in the real possibility and potential efficiency of using the proposals and recommendations for the development of grain products in Kostanay region and increasing its competitiveness.Critical analysis and generalization of materials as well as economic and mathematical modeling were used to study the problem.The study findings are based on the study of the work on the development of grain production, patterns of development of the agricultural sector of the economy in Kazakhstan and the EAEU countries, as well as legislative acts adopted in accordance with the agricultural reform, the State Program for the Development of the Agro-Industrial Complex of Kazakhstan for 2017–2021.
