Abstract: By using CHIP and CFPS household data, this paper studies the polarization of income and wealth distribution in China. The determinants of polarization are explored by the decomposition on DER indicators of income and wealth. It is found that 1) the polarization of wealth distribution increased from 2002 to 2013, while the polarization of income distribution were rather stable; 2) the polarization of wealth was higher than that of income for the same dataset and survey year; 3) urban-rural segmentation was the main contributor to polarization, although such segmentation contributed less and less to inequality; (4) wage income and household operation income were the main contributors to polarization of income distribution, and the contribution from property income to total income polarization were increasing; (5) the disposition of the polarization of property distribution by various property shows housing net value and financial assets plays a very important role in the polarization of total net property.
