The issue of income inequality is highly relevant in scientific literature. It is caused both by the population’s pursuit of achieving an acceptable level of social justice specific to a particular society and by the property, which is often attributed to income inequality, to negatively influence economic development and growth. This article conducts an analysis of cause-and-effect relations between income inequality in the Russian regions (measured by the Gini index) and the level of gross regional product (hereinafter referred to as GRP) per capita. The primary research method employed is the Granger causality test. The research is based on data from the Federal State Statistics Service on the socio-economic development of Russian regions. Direct and reversal causality tests were performed, revealing that GRP per capita influences income inequality, but not vice versa. Moreover, the logarithm of GRP per capita exhibits a bidirectional relationship with the Gini index for Russian regions. On the basis of the obtained results, it is concluded that for effective management of the issue of regional income inequality, it is advisable to use indirect methods of financial regulation instead of the direct ones and influence income inequality through indicators of GRP per capita in Russian regions, thereby creating conditions for an increase in the standard of living and average income.
