Subject This article analyzes the regional features of the relationship between Investment in Fixed Capital and Gross Regional Product variables. Objectives The article aims to determine the specifics of the implementation of investment activities in the Sakha Republic (Yakutia), taking into account the group specifics for the regions of the North of Russia and the formed specific features of investment processes. Methods For the study, I used general logical methods of scientific knowledge and the correlation method. Results The analysis of correlation dependencies of the Investment in Fixed Capital and Gross Regional Product variables by subject of the Russian Federation for quite long periods of time reveals the dominant feature for most northern regions, precisely, the absence of a significant apparent correlation between the variables or the presence of any specifics. At the national level, short time lag or lack of it clearly prevails. Conclusions Economic and statistical analysis and forecasting of GRP production depending on investments in the northern regions, including the Sakha Republic (Yakutia), are significantly hampered by the peculiarities of the dynamics of investment processes.
