伴随我国经济持续快速增长,我国城乡居民收入差距问题不断凸显.依据中国健康和营养调查的微观调查数据,利用非参数核密度估计方法对我国城乡居民收入密度曲线进行估计和分析.研究发现:我国城乡居民收入整体在持续提高,大部分城乡居民分享到了经济快速增长的成果,但中低收入家庭仍然是主体;我国城乡居民收入分布变动与改革开放进程高度相关;城镇居民收入增长速度和向高收入水平流动的速度都要快于农村居民,城乡居民收入差距持续扩大.

Most urban and rural residents shared the fruits of rapid economic growth, but low- and middle-income families were still the mainstay.
