资本-技能互补性假说认为,相对于低技能劳动者,高技能劳动者与设备资本的互补性更强,技能偏向型技术进步表现为设备资本的快速积累,会拉大高低技能劳动者之间的工资差距。本文利用1995年、2002年、2007年和2008年的中国家庭收入调查(CHIP)数据与省际数据,实证考察了设备资本积累对我国技能工资差距的影响。研究发现,1995—2008年间城镇劳动者技能工资差距持续扩大;回归结果及稳健性检验显示,设备资本积累对技能工资差距有显著的正向影响。
The capital-skill complementarity hypothesis argues that, compared with low-skilled workers, highly skilled workers are more complementary to equipment capital, and skill-oriented technological progress is manifested in the rapid accumulation of equipment capital, which will widen the gap between high- and low-skilled workers The wage gap. Using the Chinese household income survey (CHIP) data and inter-provincial data from 1995, 2002, 2007 and 2008, this paper empirically examines the impact of capital accumulation on skill wage gap in China. The study found that the wage gap between skilled workers and urban workers continued to widen during 1995-2008. The regression results and robust tests showed that the accumulation of equipment capital had a significant positive impact on wage gap.
