摘要
利用中国家庭收入调查数据(CHIPS)构造了66个城市居民的收入流动性及不平等指标,并结合历年城市统计年鉴和区域统计年鉴数据,对收入流动性和经济增长之间的关系进行了实证考察。回归发现,高收入流动性对于经济增长有着明显的正向推动作用,但随着地区内部收入不平等程度上升,这种正向作用会逐渐减弱。并且,以上两种影响在时间上具有持续性,即某一时期内的高收入流动性仍将对此后一段时期的经济增长具有促进作用,但对于收入不平等程度较高的地区,这种影响相对较弱。其政策含义是,创造公平的机会、增进社会流动性,不仅仅是一种增进社会公平的举措,也是一种促进经济增长的方法。另外,在处理收入分配问题时,动态的公平(收入流动性)和静态的公平(收入不平等)都具有重要意义。
By making use of the data from CHIPS, this paper constructs the indexes of income mobility and income inequality of the residents in 66 cities so as to conduct an empirical study of the relationship between income mobility and economic growth with reference to the data from the urban statistical yearbooks and regional statistical yearbooks over the years. It is found through the re- gression that higher income mobility has significant positive impacts on economic growth, but these effects will fade away when the income distribution becomes more unequal within the regions. Besides, these effects may last for a long time, namely, the higher income mobility within one period will still keep its role to promote the economic growth in the next period. However, in the regions with a higher degree of income inequality, this effect is relatively weak. Thc implication of the policy is that to create fair opportunities and promote social mobility is not only a measure to promote social equality but also a way to promote economic growth. In addition, when dealing with the issue of income distribution, both dynamic fairness （income mobility） and static fairness （income inequality） are of great significance.
