Abstract:

The impact of digital economy development on income gap is related to the overall realization of inclusive growth. Based on the panel data combining the individual level and the provincial level from 2010 to 2020, this paper empirically tests the influence and mechanism of digital economy development on the income gap between low-and medium-skilled labor and high-skilled labor by using the two-way fixed effect model. The research findings reveal that the development of digital economy widens the income gap, and industrial intelligence has played an intermediary role in this process. Additionally, the heterogeneity analysis shows that in eastern China and non-agricultural registered permanent residence labor groups, the role of digital economy in widening the income gap has been enhanced. However, in the central and western regions of China and agricultural registered permanent residence labor force, the impact of digital economy on the income gap is narrowing and has no significant impact. Moreover, it is found that the digital economy has no significant effect on the income gap in the early stage of development, but the effect of expanding the income gap gradually appears in the later stage. The conclusion expands the relevant research on digital economy and income gap, and provides operational suggestions for the government to formulate corresponding policies, which is helpful to promote inclusive growth of digital economy in the future.

摘要：

数字经济发展对收入差距的影响事关包容性增长的整体实现。使用2010~2020年个体层面与省级层面相结合的面板数据，采用双向固定效应模型检验数字经济发展水平对低中技能劳动力与高技能劳动力间收入差距的作用和机制。研究表明：数字经济发展水平的提高拉大了低中技能劳动力与高技能劳动力间的收入差距，且产业智能化在这一过程中发挥了中介作用。异质性分析表明：在中国东部地区、非农业户口劳动力群体中，数字经济对收入差距的拉大作用均得以增强；在中国中西部地区、农业户口劳动力群体中，数字经济对收入差距的作用分别为缩小和无显著影响。同时，数字经济发展前期对低中技能劳动力与高技能劳动力间的收入差距无明显作用，但后期扩大收入差距的作用逐渐显现。研究结论拓展了数字经济与收入差距相关的研究，为政府制定相应政策提供了可操作性建议，有助于为后期数字经济推动包容性增长蓄力。
