摘要
数字经济与人力资本是中国式现代化进程中经济高质量发展的重要因素。本文将数字经济指数与2014—2018年中国家庭追踪调查(CFPS)数据相匹配,通过划分高低技能层次的劳动力,考察了数字经济对家庭人力资本投资影响的长短期效应及作用渠道。研究发现,从短期来看,数字经济的岗位替代效应通过挤入高技能劳动力和挤出低技能劳动力,提高技能溢价水平,进而促进高技能劳动力家庭人力资本投资,反而在一定程度上挤出低技能劳动力家庭人力资本投资;从长期来看,数字经济的生产率效应促使低技能劳动力相对生产率提升,降低了技能溢价水平,进而促进低技能劳动力家庭人力资本投资,对高技能劳动力家庭人力资本投资的影响反而不显著。进一步地,家庭养老负担、宏观经济环境和政府治理水平等均会使上述影响产生异质性效果。
The digital economy and human capital are important factors for high-quality econom-ic development in Chinese-style modernisation.This paper matches the digital economy index with the data from the 2014-2018 China Family Panel Studies(CFPS)to examine the long-term and short-term effects and channels of action of the digital economy's impact on household human cap-ital investment by classifying the labor force at high and low skill levels.It is found that,in the short term,the job substitution effect of the digital economy raises the level of skill premium by crowding in high-skilled labor and crowding out low-skilled labor,which in turn boosts household human capital investment in high-skilled labor,but to some extent crowds out household human capital investment in low-skilled labor.In the long term,the productivity effect of the digital econ-omy drives up the relative productivity of low-skilled labor and reduces the level of skill premium,and thus promotes human capital investment in low skilled labor households,but the impact on hu-man capital investment in high skilled labor households is not significant.Furthermore,the above effects are heterogeneous in terms of household pension burden,macroeconomic environment and level of governmentgovernance.
