The subject of the study is to substantiate classifications of the factors of innovation development of the industry: according to the priority, traditional, barrier, according to the hierarchical level of innovation, the nature of supply demand for innovation, the peculiarity of the influence of factors on the market environment, the influence of factors on innovation localization, importance of innovations, the effect of innovation, nature of the impact, the power of influence, the type of competition, and other classifications of factors of innovation development of the industry. The need to intensify the development of Ukrainian industry in an innovative way requires the identification of the impact on these processes of various factors. To group these influences, the assessment of these factors should be done in the context of separate classes. For this purpose, it is necessary to develop a classification of innovative factors of industrial development. The purpose of the paper is to investigate and systematize the defining conditions for the activation of innovative development in the industrial sphere. The following methods were used in the work: dialectical method of scientific knowledge, analysis and synthesis, comparative, as well as the method of data generalization. It is proved that the complex non-use of these classifications for the substantiation of innovative development of the industry will improve the quality of planning and forecasting documentation and provisions of industrial policy. The applied meaning arising from the criteria for the classification of factors is based on their specific spatiotemporal and situational application, in particular, in conditions of imperfect competition. The classification of innovative factors of industrial development according to their priority is given. In this classification, the priority is determined by the importance and relevance of innovative industry development tasks on the basis of conclusions made as a result of the literature review. Summarizing the factors of innovation development in the barrier classification allows us to distinguish three aggregated groups of factors: socio-political and managerial, socio-economic, and financial. Our socio-economic analysis of innovative development factors of industry also allowed us to identify the following their classification attributes: the hierarchical level of innovation implementation, the character of demand for innovation, the nature of the impact on the market environment, the type of impact, the time horizon of action, impact on the area of innovation localization, the economic essence of innovation, the nature of the significance of innovation, innovation effect, the nature of effective impact, the power of influence, the type of competition.
