The causes of income inequality in urban China: A household assets perspective

Abstract

Despite income inequality in China being a heated topic in scholarship and public discussion, little research has explored the trend in income inequality since the mid-2010s or focused on the implications of household assets on income inequality. Using pooled cross-sectional data from the Chinese General Social Survey, we estimate income inequality at the household level from 2012 to 2021 and further examine the effects of two types of household assets (housing assets (HA) and financial assets (FA)) on income inequality in urban China, as well as the moderating effects of socioeconomic status (SES) and regional marketization. The results indicate that national income inequality was sustained at a high level between 2012 and 2021, while income inequality in urban households was higher than that in rural households. Both HA and FA were positively related to income inequality, and the latter assets had a stronger effect on income inequality. The association between the two types of household assets and income inequality strengthened along with an increase in family SES and regional marketization levels. The study highlights that FA, relative to HA, are a more important contributor to income inequality among urban households, thus extending the literature on inequality and social stratification in contemporary China by revealing the causes underlying rising income inequality from the household assets perspective.
