Income inequality in China

The economy of the People's Republic of China has a high degree of income inequality. According to the Asian Development Bank Institute, "before China implemented reform and opening-up policies in 1978, its income distribution pattern was characterized as egalitarian in all aspects." A study published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) estimated that China's Gini coefficient increased from 0.30 to 0.55 between 1980 and 2002.
