我国城镇化进程中农村收入阶层经济地位演化分析

文章运用CHNS数据库，从收入流动性视角，通过反事实计量和数值模拟方法，从众多影响因素中分解出城镇化因子对收入流动性的净效应，进而研究城镇化对我国农村收入阶层经济地位变化的影响。研究发现，农村虽存在较高收入流动性，但底层居民向上流动的机会并不大，且阶层联动结果证实了农村收入分布存在极化效应。在这一过程中，城镇化效应引起的农村收入流动性并不高，主要是引起相邻收入阶层之间经济地位转换；同时，从城镇化导致的阶层联动看，既有促进较高收入阶层和较低收入阶层向两极分化的作用，又有抑制中等收入阶层规模变小的作用。总体表明，城镇化对农村中等收入以上阶层经济地位提高更有利。

Analysis of the Dynamic Evolution of Rural Income Hierarchy Economic Status in China's Urbanization Process

In this paper, using CHNS database, from the perspective of income mobility, through the use of counterfactual measurement and numerical simulation methods to separate the net effects of urbanization on the factor of income mobility from many factors, we studied the effect of urbanization on rural income groups in China's economic status change. The study found that there is a higher rural income mobility, but the quality is not high In the rural areas. The results confirmed the presence of polarization effects on income distribution in rural areas. In this process,rural income mobility promoted by urbanization. It’s mainly caused economic status transitions between adjacent income groups. Class linkage results resulted from urbanization have increase rural income polarization and inhibited changing tendency of the proportion of the middle-income group. Overall，this paper show that urbanization is more favorable to middle-income strata above in terms of raising raise economic position.
