Analysis and estimation of the efficiency of regional US innovative systems

The study is based on methods of analysis and subsequent assessment of the effectiveness of regional innovation systems operating at the US state level, used by both Russian and English and American specialists. Based on statistical data and the results of previously published works by the author, revealing the empirical essence of the spatially heterogeneous innovation activity of the United States, characterized by the corresponding indices and integral indicators, an assessment of the effectiveness of regional innovation systems of each US state is given. Based on the results of the analysis using a number of methodological categories, carried out in the context of the country’s subregions, the author put forward some provisions justifying the spatial heterogeneity and unevenness of the development of US innovation activities in 2015-2019 from the standpoint of assessing the effectiveness of regional systems. The undertaken hierarchical clustering of regional innovation systems reflects a five-member diversity that characterizes, first of all, inventive efficiency in the spatial context of the United States, which takes various options depending on the qualitative characteristics of the scale and boundaries of various factors of innovation activity.
