数字技术创新、租金分享与企业内部收入不平等

Digital Technology Innovation,Rent Sharing and Within-Firm Wage Inequality

本文利用理论模型推演探讨了企业数字技术创新对其内部高管与普通员工收入不平等的影响及其作用机制,并基于2012—2020年A股上市公司面板数据,采用Bartik工具变量对理论假说进行了实证检验。研究发现,数字技术创新显著扩大了企业内部收入不平等。机制分析表明,数字技术创新带来的技术租金分享是企业内部收入不平等加剧的重要诱因,尤其相较于普通员工,技术租金以薪酬的形式直接流向了高管。异质性分析显示,数字技术创新对高技术密度行业的企业内部收入不平等的影响更为显著,而通过政策干预增强普通员工薪资谈判能力可以有效减轻数字技术创新对企业内部收入不平等的影响。

Based on the panel data of A-share listed companies from 2012 to 2020,this paper uses theoretical models to deduce the impact of enterprise digital technology innovation on the income inequality of internal executives and ordinary employees and its mechanism,and uses Bartik instrumental variables to empirically test the theoretical hypothesis.The study found that digital technology innovations significantly expanded within-firm wage inequality.Mechanism analysis shows that the sharing of technology rents brought about by digital technology innovation is an important inducement for the increase in income inequality within enterprises,especially compared with ordinary employees,technology rents directly flow to executives in the form of higher pay.Heterogeneity analysis shows that the impact of digital technology innovation on intra-firm income inequality in high-tech density industries is more significant,and enhancing the ability of ordinary employees to negotiate wages through policy intervention can effectively alleviate the impact of digital technology innovation on intra-firm income inequality.
