In the last decade unprecedented technological changes have taken place, resulting in the emergence of a fundamentally new economic model. Based on the widespread spread of smartphones, the world has become more “connected”. The digitalization of demand and supply contributed to the creation of entirely new digital markets managed by platform enterprises based on an open business model, that enabled external consumers and producers to connect and interact with each other. A more interconnected world generates vast amounts of data, allowing platform companies to invest in machine learning and artificial intelligence and ultimately improve their efficiency. Finally, a steady digitalization of business processes, markets and global value chains is observed. In these circumstances, approaches to value addition are fundamentally changing in the context of new dimensions of the digital economy, the analysis of which was the purpose of our study. It has been identified, that in the absence of a standardized international methodology for measuring the digital economy, the latter is so far possible on disparate development-left and national statistics. Initiatives taken at the international level to overcome national differential approaches are still insufficient, as there is a lack of statistics and variables related to digital data. It has been revealed, that the lack of quality statistics on key indicators of the digital economy makes it difficult to assess the value added in the world economy scale and international comparisons. Much of the challenges of measuring value added in the digital economy, as shown in the article, are related to the principle of “scale without mass,” the intangible nature of capital, the intense growth of large-scale cross-border data flows, and the emergence of new sources of value creation.
