Abstract
The subject of the study is the innovative activity carried out within the territorial innovation systems of the West of the USA. The latter is considered depending on the directions of the regional innovation policy in the period 1981—2020, carried out by the state authorities. Empirical confirmation of the heterogeneity and regional differentiation of innovation activity in the specified macro-region of the country allowed us to identify some trends in spatio-temporal development and features of the functioning of these systems, determined by the dynamics and nature of the interrelations of the average annual indicators of the studied economic phenomena. According to the results of the study, the conclusion is made, on the one hand, about the flexibility and appropriateness of regional innovation policy, historically a priority for the development of the innovation process in the Western United States, and on the other hand, about the change in the trend in the functioning and spatial structure of technological and institutional forms of innovation in the Pacific states of the country.
