【摘要】：构建了关于信息化水平、劳动力技能结构以及生产率的理论框架,探讨了信息化水平对生产率的直接和间接影响,以及劳动力技能结构在其中的中介作用,并利用中国省际面板数据对理论框架进行验证。结果表明:信息化水平对生产率同时具有直接影响和间接影响;信息化水平对生产率的直接影响呈现出动态的阶段性特征,两者之间存在U形关系,信息技术对生产率的促进作用只有在信息化水平达到一定程度后才能显现;信息化水平对生产率的间接影响通过劳动力技能结构的中介作用来实现:信息化水平的提升对低技能劳动者有明显的挤出效应,并带来了中、高技能劳动力需求上升,导致劳动力技能结构升级,从而促进劳动生产率以及资本生产率的提高;劳动力技能结构在信息化水平与全要素生产率之间的中介作用不显著。要使信息化更好地发挥作用,必须匹配较高水平的人力资本,劳动者需要进行持续学习与提升,以适应不断变化的社会需求。
[Abstract]:The theoretical framework of informatization level, labor skill structure and productivity is constructed, and the direct and indirect influence of informatization level on productivity is discussed, as well as the intermediary role of labor skill structure in it. The theoretical framework is verified by using Chinese provincial panel data. The results show that the level of informatization has both direct and indirect effects on productivity, and the direct influence of informatization level on productivity shows a dynamic stage characteristic, and there is a U-shaped relationship between the two. The promotion effect of information technology on productivity can only appear after the level of information technology reaches a certain degree. The indirect influence of informatization level on productivity is realized through the intermediary function of labor force skill structure: the improvement of informatization level has obvious crowding-out effect on low-skilled workers, and has brought about an increase in the demand for high-skilled labor force. It leads to the upgrading of labor force skill structure, which promotes the improvement of labor productivity and capital productivity, and the intermediary function of labor skill structure between information level and total factor productivity is not significant. In order to make informatization work better, it is necessary to match the higher level of human capital, and the laborers need to study and upgrade continuously to adapt to the changing social needs.
