要素市场、技术进步与我国劳动收入份额——基于资本体现式技术进步视角下的中介效应分析

Technological Progress and Labor Income Share in China

经过改革开放四十年的发展,我国经济已成为全球第二大经济体,但劳动收入占国内生产总值的比重仍不高,劳动收入份额相对较低。本文基于我国要素替代弹性的推测,资本体现式技术进步应是要素市场扭曲影响劳动收入份额的中介变量。基于中介效应模型的分析发现,资本体现式技术进步在要素市场扭曲和劳动收入份额间起完全中介效应。在要素替代弹性大于1的情况下,压低利率/工资率比率,可以促进与资本相融合的技术进步,即资本体现式技术进步,进而降低劳动收入份额。

Based on the speculation of China's factor substitution elasticity,the capital emphasizing technology advancement should be the mediator variable of factor market distortion affecting labor income share.The analysis based on the mediation effect model found that the capital-based technological advancement has a complete mediating effect between the factor market distortion and the labor income share.According to the research conclusions,the policy enlightenment of correcting the distortion of factor market and adjusting and transforming the technological progress path is proposed.
