Abstract

This study investigates the evolution of wealth polarization throughout the 21st century, using data from the Chinese Household Income Project (CHIP) and the Top Incomes in China (TIC) database. Our findings reveal a significant increase in polarization from 2002 to 2013, followed by a period of stabilization and signs of moderation by 2018. Decomposing polarization into alienation and identification, we observe that alienation (between group inequality) continues to rise from 2002 to 2018, while identification (within group cohesion) increases until 2013 but declines thereafter. The underrepresentation of rich households leads to an underestimation of alienation and an overestimation of identification. While these counterbalancing effects contribute to higher polarization levels, they do not alter the trend during the period. However, as the mitigating effect on identification diminishes and the growing effect on alienation intensifies, it suggests potential challenges in accurately tracking future changes in wealth polarization using survey data.
