The development of the modern economy is accompanied not only by the active introduction of innovations but also by digital technologies, which are their separate component. Currently, digital technologies cover all spheres of activity, regardless of the organizational and legal form and way of life. At the same time, very few scientific papers consider in detail the tools by which the digital economy functions. And it is virtually impossible to consider all the tools of the digital economy in a single work. It should be noted that the tools of the digital economy are only a small component of the organizational and economic mechanism of the entire digital economy. Obviously, it is necessary to consider the tools of the digital economy in the context of industries, or according to any scientifically sound classification. This paper attempts to systematize the economic research of individual foreign authors and companies. In addition, reliable statistical data are used. There is data on the quantitative impact of certain digital economy tools on gross value added, certain production indicators, the effectiveness of the use of certain digital technology tools by countries around the world. © 2022, Association Res Militaris.
