Digitalisation as a new vector of domestic enterprises development

The article explores the role of digitalisation as a key vector in the development of domestic industrial enterprises within the framework of the modern economy and the transition to Industry 4.0. It analyses the impact of digital technologies on production efficiency, competitiveness, and the structural transformation of manufacturing processes. Particular attention is paid to the implementation of digital tools such as artificial intelligence, big data, cloud platforms, and cyber-physical systems, as well as their influence on business performance. The paper also addresses major institutional and economic challenges faced by Russian enterprises, including insufficient R&D funding, outdated equipment, lack of qualified personnel, and cybersecurity risks. The research highlights the best domestic practices in digital transformation, using leading metallurgical companies as case studies (e.g. Severstal, NLMK, MMK), and assesses their technological strategies and investments in IT infrastructure. The importance of coordinated efforts between state policy and corporate strategy is emphasised, especially in the context of geopolitical constraints and technological sanctions. Ultimately, the study substantiates the necessity of a systematic approach to industrial digitalisation as a means of increasing productivity, reducing production costs, and enhancing long-term sustainability. The practical significance lies in the identification of mechanisms to support digital transition across industrial sectors of the Russian economy.
