摘要: 本文通过构建动态一般均衡模型,研究劳动力大规模转移对GDP中投资率、劳动收入份额以及经济增长的动态影响。主要结论是:劳动力转移是中国经济高增长的重要原因之一,并深刻影响了投资率与劳动收入份额变化。在劳动力转移初期,劳动力从高劳动收入份额的农业转移到低劳动收入份额的非农部门,降低了总体劳动收入份额;转移初期剩余劳动力丰富,企业支付给转移劳动力的工资低于其边际产出,导致非农部门劳动收入份额不断下降。随着劳动力转移的持续进行,转移劳动力工资越来越接近其边际产出,非农部门劳动收入份额开始上升。

Abstract: By constructing a dynamic general equilibrium model, this paper examines the dynamic effects of large-scale labour-force migration on investment rate, labour share and economic growth. The main conclusion is that labour-force migration is an important reason for China's high economic growth, and it has a profound impact on the evolution of the investment rate and labour share. In an early stage of labour migration, the labour force transfers from agriculture, which has a high labour share, to other sectors with a low labour share, which reduces the overall labour share. As the surplus labour force is abundant, the wages paid by firms to the migrant labour force are lower than its marginal output, leading to a continued decline in labour share in the non-agricultural sector. As labour migration continues, the wages of the transferred labour force are getting closer to its marginal output, and the non-agricultural sector's labour share is beginning to increase.

Key words: labour migration, economic growth, investment rate, labour share
