This section provides an overview of the materials of the 12th (120th) issue of the magazine, with which we complete the next, 14th, year of our regular communication with the reader. In the opinion of the editor, the publications in this issue serve to continue the development of our concept of theoretical economy. That is, they continue the work that we have been carrying out on the pages of our publication for almost a decade and a half. It is shown in the section what this consists of using each published work as an example. It is noted that it manifests itself, although to varying degrees, in the speeches of both well-known and new authors. The main attention in the content of the proposed issue is still paid to current problems of theoretical economics, theoretical and economic aspects of the study of new industrialization, modern problems of the world economy, and the creativity of young scientists.
