本文旨在探討金融發展與民主化程度對所得不均度之影響。利用111個國家自1970年至2009年的橫斷面資料，並且以分量迴歸方法進行實證分析，本文的發現如下。在低所得不均度的國家中，民主化程度對所得不均度有負向顯著的關係，這說明在低所得不均度的國家中，提升該國家的民主化程度有助於改善其所得不均度，另外，在各種所得不均度下，金融發展對所得不均度則是不顯著，這說明提升一個國家的金融發展能改善其所得不均度的能力不顯著。因此，提升一個國家的民主化程度較能改善其所得不均度。 This study investigates the non-linear relationships between income inequality, financial development and democracy in 111 countries over the period 1970-2009 using a quantile regression approach. The empirical results show that democracy is statistically significant and has a negative relationship in those nations that have lower levels of income inequality. Moreover, the financial development indicator is insignificant in nations with any income inequality, indicating that financial intermediary development has a minor effect on everyone. According to our empirical results, improving democracy ameliorates income inequality in countries with lower levels of inequality in terms of income distribution.
