Abstract:
This paper firstly decomposes the Erreygers index into income growth effect, income distribution effect, income flow effect and population aging effect. Then by selecting middle aged and elderly people over 45 from CHARLS and adopting mixed interval regression model, this paper obtains Erreygers index of full sample and subsampls with different characteristics. Finally it decomposes the dynamic change of income-related health inequalities. The results show that pro-rich health inequalities among middle aged and elderly people have been growing, which is mainly aggravated by income growth effect and income distribution effect, while eased by income flow effect partly and by population aging effect slightly. Different from rural area, urban pro-rich health inequalities are mostly induced by income growth effect and income flow effect.
