The article deals with the development of methods and factors that determine the R&D labor intensity in high-tech enterprises. When assessing the labor intensity of R&D, a number of problems arise related to the distinctive characteristics of scientific work: originality, novelty and creative component. Such properties do not allow a comprehensive assessment of the complexity of research work without a detailed analysis of each stage of scientific work. The problem of rationing the costs of research labor at high-tech enterprises is expressed in the fact that labor includes both creative elements of activity and repetitive stages. However, the ratio between these components depends on the nature of research and development. The implementation of R&D is characterized by a high level of innovation, which makes it extremely difficult to identify the factors that are used to calculate data for building an optimization model.
