In the context of the rapid processes of economy digitalization and integration, the issues of updating the forms and methods of public law impact on economic relations in the new modern conditions naturally arise. Taking into account the fact that control and supervision are traditionally positioned as basic management functions, the issues of substantiating public control and supervision in various areas of managerial influence in general and in the economic sphere in particular are becoming increasingly relevant. At the same time, the literature review allows to speak about the lack of common positions on the issues of structural and functional content of the category “public control and supervision in the economy”. In this regard, the purpose of the study is determined as the need for a theoretical and legal substantiation of the concept of public control and supervision in the economy, its structural and functional content and place in the general system of public administration. The materials for the study are the scientific works of domestic and foreign scientists in the field of public control and supervision, their individual areas (public financial control, public environmental control, etc.). Various opinions on the structural and functional content of public control and supervision in the economy, its individual areas, assessment of the subject composition, goals and mechanisms for implementing such activities have formed the basis for classifying the existing scientific approaches to justification of public control and supervision in the economy. It is proposed to distinguish at least three approaches to such justification: from narrow (public control and supervision as control and supervision of public authorities) to two options for a broader approach (at the national and supranational levels). The latter seems relevant from the point of view of unification of states on economic basis and formation of regional markets for goods and services in the modern economic space.
