In this article, for the first time, economic and statistical methods are used to study the interaction of innovation and investment activity and competitiveness at the regional level. The Granger test and the correlation and regression analysis are applied for the comprehensive study of individual and joint impact upon the region's competitiveness and its innovation and investment activity. The Granger test provides an opportunity to identify cause-effect relationships between the indicators of innovation and investment activity in the region. Accordingly, pairs of indicators of innovation and investment regional activity are identified and grouped together in accordance with the presence of connection, strength and direction of impact.
