Aim. To identify and systematize the factors of innovative development of modern socio- economic system.Objectives. To characterize the contribution of innovation in modern socio-economic development, including the need to achieve technological sovereignty; to analyze the approaches to identifying the factors of innovative development of modern socio-economic system; to propose the author’s systematization of factors of innovative development.Methods. The article is based on the application of mainly monographic method of research; using this method the author has studied approaches to innovative development, which are reflected in the modern economic literature. General scientific and specialized methods of scientific research were also used: analysis and synthesis, grouping method, system analysis, etc.Results. Innovations are recognized as one of the key tools of socio-economic development. Their importance has especially increased in modern conditions, when Russia was under the influence of sanctions of the collective West, limiting its technological development, which actualized the problem of achieving technological sovereignty and reducing the risks of import dependence. The problem of stimulating innovation activity has arisen and actualized, which requires an understanding of the factors influencing it. The study shows that these factors are diverse, there is no single approach to their identification and classification. This requires a combination of the available results of factor analysis in order to identify not only the composition and mechanisms of influence on innovative development of selected factors, but also to determine their mutual influence, which can act both as a stimulant and inhibitor of innovative development of socio-economic system.Conclusions. The formation of innovation potential is one of the key factors of economic growth, a necessary condition for the quantitative and qualitative development of socio-economic system. The research on identification and systematization of factors of innovative development of modern socio-economic system is a necessary prerequisite for this kind of development. The direction of further author’s research is the development of a methodology for assessing innovation potential, taking into account the impact and mutual influence of the identified factors of innovative development.
