Аннотация:In the early 2020s, the situation on the labor market worsened sharply and there was an acute shortage of skilled labor, which hindered the Russia’s economic growth. There was also a new source of information for research in this area, namely, data from online recruitment sites. The article examines the sectoral structure and dynamics of the labor markets of Russia’s largest cities for 2019–2022 based on public vacancies and CVs from the HH.ru platform. A comparison of 19 largest cities in 7 occupational areas in terms of labor supply and demand was carried out, and a trend towards an increasing shortage of personnel was revealed. It has been shown that the shortage of workers has increased significantly in industry among highly qualified workers and mainly in cities with a high share of the military-industrial complex in production. In the service sector, the shortage of workers manifests itself to a much lesser extent, but, on the other hand, employment in the service sector turned out to be much more susceptible to crisis events. There are 4 types of cities according to the peculiarities of the sectoral structure of labor supply and demand: highly developed service-digital, service-digital, service, and industrial. The main factors determining the situation in the urban labor market identified are industry specialization and position in the center-periphery system. The main advantages and disadvantages of this data source are outlined. The digitalization of the labor market is a clear example of the spatial diffusion of innovation. Changes in the labor market in the early 2020s have led to a change in the hierarchical system of diffusion of innovations within the center-periphery model with the formation of new centers as leaders in innovation implementation.
