Regional-demographic history of the Siberian borderland from the late XX to the early XXI century in the modern researchers’ works

The aim of the study is to analyze historical events related to regional development of the national economy and population of the border areas of the Altai Republic, Omsk Region, Altai Region, Tuva Republic and Novosibirsk Region in the 1990s-2010s. The study utilized general scientific methods (analysis and synthesis, induction and deduction), as well as historical methods such as comparative-historical, systemic and problem-chronological. The study of the history of regional-demographic processes in the Siberian borderland at the turn of the 20th-21st centuries allows us to trace the evolution of the national economy, the specifics of population development, and migration processes in this territory. The article analyzes publications by modern researchers on the history of regional-demographic development of the Siberian borderland in the 1990s-2010s. The study identifies three main thematic groups: the first group, devoted to the study of territorial transformations and determining the role of the border location in the development of Siberian regions; the second group, focused on examining the regional-demographic development of the Siberian borderland; the third group of studies, devoted to the evolution of economic processes in the border area of the Altai Republic, Omsk Region, Altai Region, Tuva Republic and Novosibirsk Region. The analysis of theoretical views of the Russian scientific community allows us to conduct a cross-section of the formation of scientific directions on the problems of adaptation of the population and national economy of the Siberian border territories to the conditions of market relations in the transition period of modern history of Russia. The identified scientific directions have practical significance in the formation and implementation of the strategy of regional development of Russia at present and in the near future.
