Spatial inhomogene in USA innovation

The subject of this study is the spatially heterogeneous innovation activity carried out at the regional (meso) level of the United States, analyzed and evaluated on the basis of qualitative indicators (indicators and integral indicator) of the level of innovation potential and innovation activityof regional innovation systems that have received development and statistical accounting of the results of these activities in within specific states. The identified combinations, high correlation dependence and interconnection of indicators of the innovative potential and innovative activity of regional innovation systems of the US states, made it possible to substantiate a number of trends in the development of these systems, to assess the features of spatial integration and, at the same time, the different-level differentiation of these systems, reflecting the heterogeneity and uneven development innovation activity on the “center- peripheral” principle. The final typology of regional innovation systems of the US states, based on the logarithmically normal distribution of the indices of innovation activity and the integral indicator of the level of innovative potential of the average values for the period 2015-2019, results in a qualitative spatial diversity of these systems, determined bythe joint influence of both economic phenomena on the deepening of heterogeneity and differentiation of the latter.
