摘　　要：本文通过数理经济模型的理论分析和计量经济模型的实证分析发现,决定社会产品初次分配中劳动收入份额高低的因素,除了政府的生产税税率之外,主要是劳动者的实际工资水平和生产技术水平,且二者的作用方向完全相反,都取决于要素替代弹性的大小。当资本和劳动的替代弹性小于1时,劳动者的实际工资水平越高,劳动收入份额就越高;劳动者的生产技术水平越高,劳动收入份额就越低。而当资本和劳动的替代弹性大于1时,则劳动者的实际工资水平越高,劳动收入份额就越低;劳动者的生产技术水平越高,劳动收入份额就越高。理论和实证的分析还表明,劳动者货币工资水平和实际工资水平的增长随着经济周期的波动而波动,实际工资水平增长率的波动与经济周期的波动方向相反,导致劳动收入份额也随经济周期反向波动。Through theoretical mathematical economic model and empirical econometric model analysis,this paper shows that the determinants of labor income share,in addition to government production tax,is mainly the real wage and production technology level. The influence direction of two factors is completely opposite,and their efforts will depend on the size of the elasticity of substitution. When the substitution elasticity is less than 1,the more is real wage,the higher is labor income share; the higher is production technology,the lower is labor income share. When substitution elasticity is more than 1,the more is real wage,the lower is labor income share; the higher is production technology,the higher is labor income share. The theoretical and empirical analysis also shows that the growths of money wage and real wage is fluctuation with the economic cycle,and the fluctuation of the real wage growth rate is contrary to economic cycle. Therefore,the fluctuation of labor income share is also contrary to economic cycle.
