我国农村收入流动性与居民经济地位的动态演化

利用CHNS数据,对1989—2009年间中国农村的收入流动性与居民经济地位的动态演变进行了分析。研究发现：（1）整体上中国农村居民的收入流动性呈现出不断下降且趋于稳定的态势,尤其是在2004年之后收入流动性的下降趋势较为明显。此外,不同收入阶层的收入流动性存在较为明显的差异,中等收入阶层的流动性最高,而最高收入阶层的流动性最低。（2）2006年之前收入流动性基本上有利于大多数农村居民经济地位的改善,但是2006年之后则不利于居民经济地位的改善。此外,1989—2006年间农村居民收入地位的改善更多地来自于较低收入阶层以及最低收入阶层强有力的向上流动的推动。（3）不同收入阶层经济地位的动态变化存在较大的差异。最低收入阶层向上流动较最高收入阶层向下流动要相对更为强势;较高和较低收入阶层向底层分化的态势日益明显;中等收入阶层的经济地位不容易巩固,其经济地位改善的前景不明朗。

Income Mobility and Dynamic Evolution of Economic Status in China's Rural Areas

Base on the data from the CHNS,this paper analyzes the income mobility and the dynamic evolution of economic status in rural China.The major findings are:(1) The income mobility presented a tendency of continuously decreased,and then kept stable,esp.after 2004.Meanwhile,the difference of income mobility between residents at different income levels was significant;mobility in the middle income group was higher than others.(2) The income mobility was advantageous to improve most rural residents’ economic status,except for 2006—2009.In addition,the improvement of economic status was mainly duce to the strong upward mobility of lower group during the period of 1989—2006.(3) The difference of the dynamic evolution of economic status between different groups was significant.The bottom class’s upward mobility was relatively stronger than the top class’s downward mobility;the second and forth class showed the tendency of differentiation to the bottom;the economic status of middle-income class was more vulnerable,their economic status will be improved was uncertain,and the source of its members were not sustainable.
