The purpose of this research is to study the sustainable development of the region and propose a model for the effective functioning of an innovative cluster that meets modern technologies and economic conditions. The research used empirical, theoretical, general biological methods of scientific knowledge, which allow identifying and substantiating the directions of sustainable development of territories. The work proposes a methodological approach, which consists in the development of organizational and methodological tools for the functioning of the innovation cluster in the context of ensuring sustainable regional development. The feasibility of forming an innovative cluster is due to the fact that it serves as a vector of growth in economic, production and social indicators of the efficiency of the region. The cluster within the region's economy creates infrastructure links that enable the generation, dissemination and application of new technologies and innovations. The authors highlighted the criterion features of the innovative cluster: the presence of modern infrastructure; the use of digital and information and communication technologies; specialization in innovative developments and their introduction into production; Large data and information flows using the latest digital platforms and software products a certain structure of participants. The use of an innovative cluster provides opportunities that contribute to sustainable regional development: ensuring the investment attractiveness of the region, increasing cash flows to the regional economy, increasing gross regional product, increasing business activity of production and financial structures, increasing tax revenues to the budget of the territorial unit, increasing exports of knowledge-based products, developing the regional industrial complex and related industries. The creation of innovative clusters contributes to the sustainable development of the territories within which they operate. The
