State management of the socio-economic development of Russian society is carried out in the context of unprecedented anti-Russian sanctions, which necessitates a rethinking of approaches to economic analysis, which is the theoretical basis for the development of long-term forecasts of socio-economic development and socio-economic policy of the state. In the process of economic analysis in the emerging conditions of public administration, along with economic ones, it is necessary to take into account other significant social phenomena and processes, including the political and legal systems, social values immanent in Russian society, which is possible through the application of institutional economic theory based on an interdisciplinary approach to economic analysis. However, firstly, the founders of institutionalism are American scientists who analyze the American political and legal system and the culture of the American people, which excludes the direct use of institutionalism for the analysis of Russian political and legal reality and, secondly, to date, institutionalism has not been incorporated into a unified economic theory. formed. Based on the fact that institutionalism is recognized as a promising direction in the development of economic theory, the article points out the need for its adaptation to the socio-economic conditions of the development of Russian society, for which, first of all, it is necessary to develop common approaches to the definition of such basic concepts used in Russian institutionalism, as "institutional structure", "institutional environment". The analysis of the approaches of American and Russian scientists to the definition of the concept of the analyzed terms is carried out, on the basis of which, taking into account the Russian political and legal system, the author's definitions of the concept of "institutional structure" and "institutional environment" are proposed. The conclusion is substantiated that the use of these concepts in the proposed interpretation in the course of institutional analysis corresponds to an interdisciplinary approach to economic analysis, immanent institutionalism, is aimed at establishing institutionalism as a unified economic theory adapted to the realities of Russian society, capable of acting as a theoretical basis for effective public administration.
