| 内容提要 | 城镇化受到多种因素的动态变化影响，这些因素不仅决定了城镇化的路径，而且影响着劳动收入不平等的变化，从而共同决定了城镇化与劳动收入不平等之间关系的规律性和多样性。本文从劳动市场均衡条件出发，对城镇化水平变化率进行了动态分解，并且应用对数方差和对数绝对差指标，从城镇化的视角动态分解了劳动净收入和总收入的不平等关系式。理论分析表明：一方面，城镇化水平的提高率低于城镇正式部门就业规模的扩张率，城镇正式部门的扩张率高于劳动收入不平等的上升率，并对劳动收入不平等变化率有先正向而后反向的影响；另一方面，城镇化的相关因素对上述数量关系的影响是不同的。基于中国1983—2015年相关数据的经验分析基本上验证了上述结论。本文还结合城镇化结构优化和劳动收入平等约束，讨论了我国下一步城镇化的相关政策选择。 |
| Abstract | Urbanization is affected by many factors. These factors not only determine the path of urbanization, but also make an influence on the evolution of earning inequality. As a result, these factors codetermine the regularity and diversity of the relationship between urbanization and earning inequality. This paper decomposes the change rate of urbanization under labor market equilibrium condition. At the same time, this paper applies the indexes of logarithm variance and logarithm absolute deviation to decompose the inequality formula of the net income and gross income from the dynamic perspective of urbanization .Theoretical analyses show that: on the one hand, the increasing rate of urbanization is lower than the expanding rate of employment scale from urban normal factors, and the expanding rate of urban normal factors is higher than the increasing rate of earning inequality which has a positive influence first and then negative influence on the change rate of earning inequality. On the other hand, the different factors related to urbanization have a different impact on these numerical relationships. The empirical analyses of China between 1983 and 2015 basically verify the conclusions. Finally, this paper discusses the policy choices for urbanization combined with the optimum structure of urbanization and the constraints of earning equality in China. |
