Methodology for assessing the level of digitization development of complex economic systems

The rapid development of digitalization processes is one of the characteristic features of the modern technological transition. The efficiency of functioning of economic systems largely depends on the level of use of digital technologies today. This actualizes the problem of quantitative assessment of the level of digitalization of economic systems. For simple economic systems, this problem has known solutions. For complex economic systems, a unified approach to solving this problem has not yet been developed. Mostly used are various evaluation systems based on ratings. The article attempts to develop a methodology for assessing the level of development of digitalization of complex economic systems based on a recurrent procedure of level-by-level additive convolution ofprivate indicators of the level oof digitalization.
