Spatial economic systems: methodological tools and applied solutions

Despite its high demand with regard to application, the scientific direction of the problems of the development of spatial economic systems is the least developed block in the field of studies of the territorial organization of the economy. The analysis of spatial economic systems requires a special toolkit, different from the methods of regional analysis. The combination of methodological principles of new economic geography, methodology of "new locality", system-dynamic and synergetic approaches allows to obtain new scientifically significant results. In terms of expanding the application potential, the article presents a study of the dynamic characteristics of spatial economic systems, namely, the rates of economic growth and their stability, the region's involvement in the country's economic space, and the flexibility of the sectoral structure of production. According to the results of the study, four patterns of the economic dynamics of the regions have been revealed. Increased spatial connectivity, diversification of production, and the development of new industries can be the possible mechanisms for the adaptation of the regional economy to new conditions and sources of recovery growth.
