The purpose of this study is to identify the interrelationships of the main factors inherent in the regional economic system. The study was conducted using the method of correlation analysis. The scientific novelty lies in the development of conclusions on the interdependence of key indicators of regional development based on the statistical data of the subjects, taking into account the data of Rosstat, the Ministry of Finance of Russia and the Central Bank. The levels of relationships between the indicators were identified and statistically evaluated, which allowed us to conclude about the inherent "path dependence" of a number of factors. The calculation of indicators and visualization of results are prepared using data analysis algorithms in the programming language R. Conclusions are drawn about the high mutual conditionality of investments and accumulated fixed assets in the region, the credit load and the volume of deposits, investments and own budget revenues, etc. The results obtained can be used in the development of regional economic policy measures.
