The Fourth Industrial Revolution has largely contributed to the reorientation of the manufacturing industry (under the concept of Industry 4.0) towards the implementation and adaptation of such digital tools as big data, the Industrial Internet of Things, blockchain and many others to its own needs and the needs of the market. All the above technologies provide the basis for digital platforms, which are an essential activity component for network innovation-intensive industrial clusters; it follows that their essence and characteristics represent a relevant research area, which determines the novelty of this research. Thus, the research aims to establish the essence and identify the characteristics of digital platforms for network innovation-intensive industrial clusters as well as to develop a classification of digital platforms. The paper uses the following methods: general scientific methods (synthesis and analysis), methods of interpretation (including graphical ones) and comparison, the combination of which has made it possible to achieve the goals and objectives of the research, to reveal the essence and characteristics of digital platforms for network innovation-intensive industrial clusters. The results of the research are as follows: key concepts associated with the concept of a clustered economy have been revised, and the authors have developed their own definitions of "a network innovation-intensive industrial cluster" and "a digital platform for a network innovation-intensive industrial cluster"; the specifics of the innovative and digital potentials of such clusters have been considered in detail; the structure of digital platforms has been examined, the authors have suggested a classification of digital platforms based on the level and area of their utilization and on the scale of operations. The practical significance of the research results is determined by their applicability in the operations of innovation-intensive industrial clusters in terms of establishing the essence of their innovative and digital potentials and defining the role of and opportunities for using digital platforms in their dayto-day and strategic operations.
