摘要
本文基于2008-2018年的制造业上市公司数据,采用RIF回归方法,通过企业内部薪酬差距和企业间薪酬差距两个角度,考察创新对收入不平等的影响及其影响机制。研究发现:创新不仅拉大了企业内部的薪酬差距,也拉大了企业间管理层的薪酬差距;创新并未有效地缩小企业间员工的薪酬差距;创新通过“生产率效应”拉大了薪酬差距,但通过“替代效应”减小了薪酬差距。最后,本文还发现创新影响收入不平等的效果在国企与非国企之间基本类似,但在东部与中西部地区之间存在一定差异。
Based on the data of listed companies in 2008-2018,this paper uses RIF regression method to examine the impact of innovation on income inequality from the perspectives of internal salary gap and inter-enterprise pay gap,then we try to reveal its impact mechanism.The results show that innovation widens the salary gap among employees of the company as well as the salary gap among managers.Innovation has not effectively narrowed the salary gap among the employees from different enterprises.Innovation can wide the salary gap through the“productivity effect”,but also can reduce the salary gap through the“substitution effect”.Finally,this paper also finds that the effect of innovation on income inequality is basically similar between state-owned enterprises and non-state-owned enterprises,but there are some differences between the eastern region and the midwest region.
