By examining the relationship between financial inclusion and income inequality while focusing on financial and macro data of 62 countries over the period 2003 – 2017, this paper analyzes the impact of quality factor of financial inclusion on the improving income inequality. It is able to use the results of its empirical analysis to draw the following four conclusions. First, the financial inclusion plays an important role of reducing income inequality in low income countries in which the scale of income inequality is relatively high while the tax progressivity has less impact on those countries. Second, the effect of quantitative expansion of financial inclusion is rather strong in high income countries while its reducing impact of income inequality is very weak in low income countries. In case of Korea, it has a similar pattern with the case of high income countries. Third, The expansion of quality factor of financial inclusion has great impact of reducing income countries in low income countries, and such a tendency is a little stronger in case of Korea too. Finally, under the factor component analysis(PCA), the quality factor of financial inclusion is the first factor in low income countries while the quantitative factor of financial inclusion is the first factor in high income countries.
