Abstract
The research of socio-economic differentiation and regional convergence development allows us to give an objective assessment of the current state of the country's economy at the sub-territorial level. Research of the process of industrial regions convergence of the Russian Federation for the development of proposals aimed at eliminating the identified proportions. Check the scientific hypothesis about the presence of significant differences in the degree of development processes convergence among various groups of Russian regions, formed according to the principle of industry specialization of the production complex. The research uses economic, mathematical, and statistical information processing methods. The theoretical framework of the study is based on the works of Russian and foreign researchers in the field of regional development. The information basis includes statistical databases for the period 1999-2019. As a result of the analysis, it was revealed that for the regions of the Russian Federation it can be considered that there are no convergence processes. When conducting research on industrial regions with different specialization of the industrial complex, it was revealed that convergence processes were periodically observed among agricultural ones, including due to β-convergence, while regions with raw materials and industrial specialization had a pronounced divergence of development.
