摘要
基于2011—2020年A股上市公司数据,运用多期双重差分模型实证评估了数字基础设施建设对企业劳动收入份额的影响效应及作用机制。研究表明:“宽带中国”城市试点政策总体上显著提高了企业的劳动收入份额水平;“宽带中国”城市试点政策通过提高工资水平、优化就业技能结构以及降低劳动生产率促进劳动收入份额的提高;但“宽带中国”城市试点政策带来企业技术水平的提高会产生“替代效应”,进而对劳动收入份额产生抑制作用;同时,“宽带中国”城市试点政策对不同特征企业劳动收入份额的影响存在显著差异。
Using data from A-share listed companies from 2011 to 2020,a multi-period double-difference model was applied to assess the impact and mechanisms of digital infrastructure construction on the labor income share of enterprises.Findings demonstrate that the“Broadband China”urban pilot policy notably elevated the overall labor income share.This was facilitated by increased wage levels,optimized employment skill structures,and reduced labor productivity.However,the technological advancement within enterprises due to the“Broadband China”urban pilot policy could potentially curtail labor income share through the substitution effect.This policy's impact on labor income share varied significantly due to diversified enterprises'characteristics.The conclusions provide crucial policy insights to stabilize residents'labor income,foster shared prosperity,and drive Chinese modernization amidst digital transformation.
