Abstract

This study examines the moderating impact of individual income tax on skilled wage premiums in China from 2003 to 2017 using a non-parametric pointwise regression model. The findings indicate that: Individual income tax has an inverted U-shaped moderating effect on the wage premium between high-skilled and low-skilled workers; it can reduce the skilled wage premium of low-skilled individuals but not the skilled pay premium within the group of high-skilled workers.
