We live in an era of digital transformation. Informatization of society has led to new realities, to a new paradigm of the state development, economy and society as a whole. Today, the main trend of Russian domestic policy is digitalization, accelerating the pace of technological change, opening up new opportunities for economic growth through digital transformations, including changes in the regions. However, the following problem remains unresolved – What is the digital economy and how to evaluate it? The authors offer their interpretation of the digital economy definition and the solution of its statistical evaluation problem. The study is devoted to the analysis of the impact of digital transformation on the socio-economic development of territories; attempts are made to solve the problem of assessing of digitalization contribution to the economy of the country and regions. An analysis of the advantages and disadvantages of various methods and techniques for assessing the unevenness of the digitalization process of the state, business and society has been performed. Well-known methods and indicators are not always effective, for example, the problem of the formation of the socio-economic indicators system, indicators of the digital transformation level at the municipal management level remains. To assess the digitalization level of business and households, we propose using integrated indicators calculated using 5 primary business indicators and 6 households indicators. A methodology for assessing of disproportions scale in the digital transformation of the Russian regions is proposed in the work. The authors performed a typology of the Russian Federation constituent entities according to the digitalization degree of business and households. Using the regression model, the dependence of the region economic development on the level of digital transformation and the territories disproportions degree is proved.
