This section provides an overview of the materials presented in issue 11 (131) of our journal. This issue is being published during the 15th anniversary of our online publication: it was registered in November 2010, and its first issue was released on the morning of January 1, 2011. The journal immediately announced its advancement of the concept of theoretical economics as a new paradigmatic mainstream in socioeconomic research. Over the course of a decade and a half, communicating with readers, the editorial board and authors have persistently and consistently developed and advanced this concept. According to the editor, the publications in this issue offer ideas for the further development of this concept. In other words, they continue the work we have been doing on the pages of our online publication for the past decade and a half. This section illustrates this development through the example of each work presented in this issue. The editor notes that this is evident, albeit to varying degrees, in both the contributions of well-known authors and new ones. The focus of this issue’s content is traditionally, first, on current issues of theoretical economics, explored by the editor himself, his colleagues from fraternal Belarus, P.S. Lemeshchenko and N. Ma, and Professor N.K. Vodomerov from Kursk. Second, on the theoretical aspects of the new industrialization, examined in the works of I.B. Nuriyev and his co-authors from Novosibirsk, E.E. Golovchanskaya from Moscow, and I.G. Gerashchenko from Volgograd. Third, attention is drawn to the publications of young researchers, exemplified by the works of Yu.O. Andrianova from Moscow, and S.P. Kirilchuk and Yu.Yu. Nesterenko from Simferopol. The methodology of this editorial study is naturally based on our proposed concept of theoretical economics. The scientific novelty of this work lies in identifying the contribution of the articles published in this issue to the development of this concept.
