摘要
该文通过建立二元经济结构的模型,分别分析了城市化水平、劳动力流动、产业结构变迁以及城乡收入差距对劳动收入份额的影响。研究发现,产业结构和城乡收入差距与劳动收入份额之间均存在着负相关关系,但劳动力转移并不一定带来劳动收入份额的下降,而城市化与劳动收入份额之间会存在着正相关关系。劳动力转移对劳动收入份额的影响,取决于从农村流入城市劳动力的数量,以及进入城市后所从事工作的资本密集度。城市化对劳动收入份额的影响,取决于新加入城市的人口所从事的工作的资本密集度。以上结论得到了1993-2014年间的省级面板数据的支持,实证检验表明在中国的二元经济结构中,产业结构的变化对劳动收入份额的影响最大,城市化次之,城乡收入差距再次之,劳动力流动的影响最小。
This study constructs a dual economic model to analyze the effect of urbanization,labor mobility,industrial structure evolution and urban-rural income inequality on the labor share. It is found that the evolution of industrial structure and the growth of the urban-rural income gap will reduce labor share. But labor mobility does not necessarily bring about the labor share decline,which depends on the amount of the labor mobile to city and the capital intensity of their jobs’ categories. Meanwhile urbanization could have a positive correlation with the labor share,and this also depends on the capital intensity of their jobs. Empirical studies using 1993-2014 Chinese provincial panel data support above findings,which shows that in a dual economy like China industrial structure changes impact the labor share most,followed by urbanization,urban-rural income gap,and labor mobility has the minimal impact.
