The analysis based on the China Labor-force Dynamic Survey data shows that China’s education return rate has significant difference in income hierarchies, that the education return rate rises with the rising of income level as a whole, that there is big difference between lower income hierarchy and other income levels, that the education return rate of middle income hierarchy is the highest, and that the labor immigration can obviously promote the education return rate for receiving high education of middle and high income groups and for receiving middle education of middle income group to further strengthen their income advantages. The contribution of education return rate to income difference is more uneven than education level, as a whole, the labor immigration is conducive to narrowing the income gap related to individual education (especially high education). Thus, the allocation of education resources should be helpful to raise the education level of lower income groups, we should eliminate the systematic barrier resisting labor immigration to narrow the income gap resulting from the difference in individual education.
