The article updates the issue of developing a methodology for analyzing investment activity and investment development at the regional level. The aim of the study is to generalize and further develop the methodological principles of analyzing investment processes at the regional level. It is proved that the analysis of investment processes in the region gives a more complex picture regarding the volumes, dynamics, structural characteristics and efficiency of investment activities in the regional economy. In general, in order to carry out a systematic and comprehensive analysis of the processes of development of investment activity and activity in the region, it is important to form a full-fledged regulatory and methodological support, consisting of approaches, methods and tools of analysis and diagnostics, as well as a system of indicators. It is established that the results of the analysis are conclusions regarding, on the one hand, the investment activity of economic entities, and, on the other hand, the quality of the regional investment policy. It has been proven that the regulatory and methodological support for the analysis of investment processes in the region consists of two blocks: (1) microeconomic, (2) macroeconomic. It is determined that the criterion of the first block is the ease (operational, cost-effectiveness, efficiency) of passing through the stages of the investment process, while the second block is the contribution (volume, structure, quality) of investments to the socioeconomic development of the region. It is substantiated that the introduction of the system of analysis of the investment environment at the regional level involves the following procedural stages: institutionalization of the practice of analysis; formation of resource support; identification of persons responsible for the analysis; consolidation of the system of indicators prepared by official statistics bodies; forming a database of experts; development of clear regulations for surveying and evaluating the characteristics of the investment environment; determination of procedures for "reaction" of authorities to the results of the analysis, publication of the results.
