摘要
本文基于2000-2016年中国28个制造业行业的面板数据,运用CES函数测度中国制造业行业资本与劳动的要素替代弹性和技术进步偏向性,并在此基础上,进一步探究偏向性技术进步与劳动收入份额的关系。研究结果表明:(1)全样本下,28个制造业行业的资本与劳动的要素替代弹性在2000-2016年均小于1,资本与劳动呈现互补关系且制造业的技术进步总体偏向于资本;(2)制造业的技术进步偏向性对劳动收入份额有显著的抑制作用;(3)不同创新来源对劳动收入的影响存在异质性,其中技术原创对劳动收入份额具有正向效应,技术引进对劳动收入份额具有负向效应。
Based on the panel data of 28 manufacturing industries in China from 2000 to 2016,this paper uses CES function to measure the factor substitution elasticity and technological progress bias of capital and labor in China’s manufacturing industry,and further explores the relationship between biased technological progress and labor income share.The results show that:(1)in the whole sample,the substitution elasticity of capital and labor in 28 manufacturing industries is less than 1 in 2000-2016,capital and labor are complementary,and the technological progress of manufacturing industry generally tends to capital;(2)the technological progress bias of manufacturing industry has significant inhibition on the share of labor income;(3)the impact of different innovation sources on labor income There is heterogeneity in the impact,in which the original technology has a positive effect on the share of labor income,and the introduction of technology has a negative effect on the share of labor income.
