This paper presents the inequality measures for different spatial groupings in China from 1997 to 2007. The intra-provincial inequality within each province, that is, the inequality amongst the county-level units within each province, is derived. It is found that the levels of inequality in the nation, the coastal and inland regions, the four economic zones, and most of the provinces increased over the study period. The levels of inequality amongst the county-level units in the eastern and western zones were higher than that in the other zones over the study period. The results show that the provinces with a high level of inequality are mostly situated in the northern part of China. The provinces are observed to have very different patterns of inequality, even if they are in the same economic zone. Moreover, it is found that Jiangsu had the highest level of intra-provincial regional inequality in 2007.
