Purpose of the research: based on theoretical analysis, to develop a classification and structure of human capital, allowing for its development most optimally. The structure of human capital, proposed by the authors and considered in this article, consists of 5 main components, namely, demographic capital, educational capital, labour capital, research capital, socio-cultural capital. Along with the proposed structure of human capital, 8 third-party human capital structures by various authors were analyzed. To confirm the uniqueness of the human capital structure proposed by the authors, 25 state programs implemented in the Sverdlovsk region were analyzed. In this study, the authors propose their own classification of human capital, which meets modern realities and can be digitized for each item, which makes it possible to directly influence labour productivity in several aspects. Also, an important conclusion of this article is the need to develop educational and research capital, since these components of the proposed structure play an important role in innovative and economic development. The study's theoretical significance consists of proposing a new classification of human capital, which fully reflects its essence from different angles. Based on this, it allows formulating new hypotheses for the development and improvement of human capital. The practical significance lies in the relevance of the proposed structure for the next 10-15 years and specific recommendations for the development of educational and research capital in the Sverdlovsk region and other regions of the Russian Federation.
