The role and significance of commercialization of innovations, the importance of the innovations commercialization processes development in modern society have been revealed. It has been proven that commercialization is an important element of innovative activity, as it represents the process of transforming the results of scientific and technical activity into a product and their further effective implementation on an industrial scale, and acts in the form of a kind of intermediary activity that connects scientific and technical and commercial activities and ensures the development of market relations and as a catalyst reflects their condition. The theoretical approaches to the interpretation of the concept of "innovations commercialization" by individual scientists have been analyzed. The essence and content of the process of commercialization of innovative activity, the directions of commercialization of innovative activity have been considered. An overview of the forms and methods of enterprises innovative products commercialization was carried out. The model for choosing priority methods of innovative products commercialization was presented. The modern mechanism of ensuring the commercialization of innovative technologies and the scheme of the functional construction of the mechanism of commercialization of the results of innovative activity were considered, which will allow to determine the degree of commercialization of the results of innovative activity even at the early stages.The key problems of commercialization of innovative products were outlined.The conclusion was drawn: that the innovations commercialization is an important element of the innovation process, which is explained by the fact that it (innovations commercialization) represents the process of transforming the results of scientific and technical activities into a product (service) and their further effective implementation on a large scale. And the success of the innovation commercialization is of strategic importance for the innovator’s innovative activity, as it determines their competitiveness and is an important component of the development of the economy as a whole.
