The article is concerned with the study of the theoretical and methodological patterns of the genesis of labour relations during evolution of socioeconomic systems. The approach developed by the authors makes it possible to single out the basic blocks of the labour relations system, considering the actors and objects of the relations. Adopted as a basis, such an approach makes it possible to describe the labour relations of any economic system. The allocation of mandatory elements (objects) and subjects in the structure of labour relations makes it possible to disclose the content of the category "labour relations". The relevance of theoretical studies of the characteristics of the economy at a substantial level, the increased interest in the methodology and theory of economic knowledge is due to the inconsistency and alternativeness of the current stage of development of the world economy and global society. For Russian society, such studies are determined by the exceptional complexity of transformation processes and the prospects for its evolution.
