A calculated indices based sectoral and regional analysis of investments has enabled us to assess the achieved level of investment differentiation, to identify the most significant contributions to the sectoral concentration and regional specialization, as well as to perform a comparative analysis of investment flows. In order to address this wide range of topical issues, as studies have shown, we may use the methodology proposed by Mr. P. Krugman. The economic and mathematical models developed in this study can be widely applied to monitor and diagnose the level of investment in regions and industries, as well as to transform the national policy in order to increase the return on fixed capital investment of enterprises and organizations. The methodological significance of this work consists in the development of tools describing the investment processes in Russia, as well as in the assessment of the current level of their territorial and sectoral differentiation. We believe that further study should be conducted based on the data that characterize investments at the local municipality level.
