中文摘要：

不同技能劳动的划分一直是劳动力市场的一个重要研究视角,也是难点之一。文章创新性地采用模糊聚类方法测算了我国第二产业中各行业的劳动高技能性,推算了高低劳动技能行业的工资比率,并进一步实证分析了高低劳动技能行业的工资比率、FDI等因素对我国劳动收入份额的影响。研究结果表明：（1）由于高技能劳动一般与资本结合得更为紧密,高低劳动技能行业工资比率的提高抑制了劳动收入份额的上升;（2）FDI引入对我国劳动收入份额也具有负向影响。

英文摘要：

The division of labor with different skills is always an important research perspective and issue in labor market.This paper employs fuzzy clustering technique to estimate the high labor skill of industries in the secondary industry and measures the wage ratio of industries requiring high-skilled labor to ones requiring low-skilled labor.Furthermore,it empirically analyzes the effects of factors such as the wage ratio of industries requiring high-skilled labor to ones requiring low-skilled labor and FDI on labor share in China.The results are as follows： firstly,owing to the close relationship between labor with high skill and capital,the increase in the wage ratio of industries requiring high-skilled labor to ones requiring low-skilled labor inhibits the rise in labor share;secondly,the introduction of FDI has a negative effect on labor share in China.
