随着农民工短缺的出现和扩大，关于中国是否已经达到刘易斯拐点（LTP）的争论越来越多。本文利用中国全国农产品成本效益调查数据，分析农业部门劳动力成本、劳动力投入、资本投入和边际劳动生产率的变化。本文发现，自2004年以来，农业部门劳动力成本快速上升，非熟练工人的工资也快速而显著地上涨。20世纪90年代中期以来，总劳动投入和三种主要粮食作物单位劳动投入不断下降，资本劳动比迅速上升。1980-2004年和2005-2008年期间，粳稻的劳动产出弹性和边际劳动生产率都有较大的上升。本文提供的证据可以帮助人们澄清中国是否已经达到LTP的争论。
With the emergence and expansion of a shortage of migrant workers, there is much debate over whether China has reached Lewis turning point (LTP). This paper uses China's national farm product cost-benefit survey data to analyze changes of labor cost, labor input, capital input and marginal labor productivity in the agricultural sector. This paper finds that rapid rise of labor cost has happened in the agricultural sector since 2004, accompanied by rapid and significant wage increases for unskilled workers. Total labor input and labor input per unit of three major grain crops have been falling and capital-labor ratio has risen rapidly since the mid-1990s. Output elasticity of labor and marginal labor productivity of japonica rice has risen by a large extent between the period 1980–2004 and 2005–2008. The evidence provided in this paper can help people clarify the debate on whether China has reached LTP.
