“…The conducted research is based on the theoretical basis created by both foreign and Russian scientists. Of particular value were scientific works in which: conceptual approaches to the origins of the effects of trade relations are outlined (Viner, 1950); theoretical foundations of economic integration are revealed (Krugman and Venables, 1996;Lumineau et al, 2021;Tan et al, 2020), the dynamics, stages, and forms of economic integration associations (Balassa, 1967;Glazyev, 2019; Postel-Vinay, 2020); the forecast of the strength of economic integration in the terms of global challenges is given (Chia and Plummer, 2015;Shenkar et al, 2020); the applied aspects of the analysis of integration processes are revealed (Akhunbayev et al, 2020;Froese et al, 2021;Kets and Sandroni, 2021;Kӧpid, 2015); the vision of possible solutions to integration problems (Jones, 2015;Krugman and Venables, 1996;Oliveira and Lumineau, 2019). The statistical data and analytical reports of the Eurasian Development Bank, international reports of researchers representing the EU and EAEU member states, as well as other materials of other authoritative organizations served as an information base.…”
