Aim. The article shows the increased productivity of heterodox approaches in the part of economics that studies the problems of the world economy, including regional integration.Methods. Illustrations of the apparent paradoxicity (for representatives of the economic mainstream) of geopolitical and world economic dynamics after 2022 are used to explain the importance of analyzing economic processes in the world economy, taking into account approaches of related social disciplines. The connection of some important scientific results of Russian scholars in the field of economics with the achievements of historians, orientalists and cultural scientists, representatives of economic and political geography and studies of international relations is shown.Results. The article describes the boundaries of the mathematization of the considered segment of heterodox analysis related to the unreliability of world economic statistics, with examples of the successful application of approximate (in a broad sense relative to mathematical terminology) calculations to assess shifts in foreign trade and foreign direct investment in contemporary Russia. The author demonstrates that the heterodox approach reveals the absence of contradiction between Russia’s intensification of Eurasian economic integration (including within the narrow limits of the EAEU) and our country’s efforts to build a more equitable polycentric world order, including strengthening the BRICS format. Greater interdisciplinary transparency for heterodox economists against the background of representatives of the mainstream, among other things, makes it possible to intensify fruitful cooperation between scientists and practical analysts representing analytical centers — think tanks of the post-Soviet space and neighboring countries in the interests of developing integration projects.Conclusions. The proposed methodological framework can enhance the effectiveness of the work of the analytical community of Russia and its friendly countries in obtaining new applied conclusions in the economic sphere, especially in terms of enhancing the effectiveness of integration efforts in Greater Eurasia. At the same time, heterodox economists are more receptive to cooperation with historians, political scientists and other analysts who have focused on Eurasian economic integration.
