Grey Income Debate
Grey income was estimated as high as 5.4 trillion Yuan in 2010 (Wang Xiaolu, 2010)
Grey income is an issue to be concerned, but probably is not as serious as that estimated by Wang (Luo, Yue, and Li, 2010)
3. Implications for China’s
Economic Growth in the Future
Decreasing poverty, either in income poverty or multidimensional poverty, but
• Low standard of poverty line
• Less focus on other dimensions
• Less focus on Children poverty
•Segmentation of Policies
The income inequality probably has reached to a turning point, at least in some aspects, but Income inequality is still serious
It’s not sure whether the trend will be sustained?
Dramatic widening urban inequality
Will transfer schemes among regions and between rural and urban areas be affordable and sustainable?
Achieving a more equitable and sustainable economic growth
Improve human capital
Promote Urbanization
Growing middle class and structural change
Reform the factor market
