Comparison of innovative development indexes in the space of regional differentiation characteristics

Currently, one of the priorities of the country's development is the transition of the economy to an innovative path of development. Analysis and evaluation of innovative development at the regional and national levels, quantitative assessment of regional innovation activity, and development of methods for evaluating the effectiveness of interaction between science and business that allow choosing the right strategies for solving management problems are of particular relevance. The subject of the research is the indexes of innovative development of regions. The purpose of the study is to compare the indexes of innovative development of regions and identify indexes that do not have significant differences. Eight indexes describing the innovative development of Russian regions are compared. We use four of the author's indexes, published earlier: the index of technical efficiency innovative space for international patent applications TEMPZ, the index of technical efficiency innovative space for patent applications TEPZ, the index of technical efficiency innovative space issued patents TEPV and the index of technical efficiency innovative space developed for new technologies TETECH. Along with the author's indexes, four other indexes with a similar applied focus are considered, published by the Institute for Statistical Studies and Economics of Knowledge (ISSEK) in National Research University - Higher School of Economics (HSE), RIA rating, and Association of Innovative Regions of Russia (AIRR). In the course of the study, a comparative analysis of the indexes of innovative development in the space of expert-defined characteristics of regional differentiation was made. Analysis of the cosines of the angles between the indexes constructed using the beta coefficients of the regressions of these indexes on the differentiation characteristics allows us to refine the results of correlation analysis and identify a subset of indexes that are not distinguishable when solving control problems parameterized using the differentiation characteristics.
