劳动收入份额下降对收入不平等的影响——兼论皮凯蒂的《21世纪资本论》

the Impact of Labor Income Share's Dropping on Income Inequality——Comments on Thomas Piketty's Capital in twenty-first Century

皮凯蒂在其著作《21世纪资本论》中,对过去300年欧美国家丰富的收入、财富数据进行了时间序列分析,认为20世纪70年代以来,欧美国家的收入与财富不平等已经扩大,出现了"两个世界"现象。本文借鉴其研究成果,认为中国的国民收入要素分配面临劳动收入份额持续下降与财富集聚的双重压力,这导致中国的收入不平等有扩大的倾向,通过实证检验,提出政策建议:提高劳动收入份额,改变资本偏向型战略,实现收入代际流动以及充分发挥国有企业的作用等。
