Peculiarities of regional development in economy digitalization

The digital transformation of the modern economy necessitates a thorough analysis of the factors determining regional differentiation in the use of digital technologies by organizations. The relevance of the study is driven by the need to identify and systematize key aspects of digitalization at the level of economic entities, which is crucial for developing effective regional development strategies and overcoming the digital divide. This paper examines the theoretical foundations of digitalization and digital transformation, assesses current trends and the scale of economic digitalization at global, national, and regional levels, with particular attention to e-commerce dynamics as a manifestation of these processes. The insufficiency of analyzing e-commerce markets alone for a comprehensive assessment of territorial digital development is substantiated, and a methodology for calculating the Integral index of organizations' digitalization (IIOD) is proposed. Based on the IIDO, an analysis of regional differentiation in the digital development of organizations in Russia is conducted, identifying leading and lagging regions. The level of digitalization of organizations is compared with regional economic development indicators to assess the representativeness of the proposed index.
