Main Provisions of the Methodology for Studying the Dynamics of Changes in the Spatial Localization of Economic Sectors and Determining Regional Development Priorities

The existing structure of regional industries and territorial distribution of productive forces predetermine state regulation in the field of industrial, regional, and competitive policy. Intensified transformation processes (transition from a resource-based to a service high-tech model of the economy) in the face of severe investment, geopolitical restrictions require a fundamentally new methodological approach to determining the priorities for the development of industries, their territorial localization and the management system of regional production systems. The paper presents the main provisions of the methodology for studying the spatial localization of economic sectors at the regional level, based on the principles of the "new" spatial economy, as a synthesis of modern theoretical and applied research with the inclusion of theoretical and methodological tools for empirical analysis of long-term trends characterizing changes in the structure of the Russian economic space and territorial placement of productive forces to select the priorities of regional policy. The purpose of the study is to create a model for determining the key areas of sustainable development of regions, taking into account the factors of spatial development based on aggregation, the development of a theoretical basis, methods, ways for analyzing the spatial localization of economic activity. The article contains the key aspects of the methodology: theoretical basis, stage-by-stage decomposition of the analysis, a set of econometric methods for solving the tasks posed, the structure of the empirical results obtained, which determines the novelty of the study in the context of the development of the theory and methodology of spatial economics.
