摘　　要：数字技术的全面发展与企业运营的深度融合,已成为企业探索新增长机会和提升全球价值链分工地位的关键因素。本文基于中国上市公司数据和中国海关数据库,通过测算企业的数字化转型程度及其与出口国内附加值率的关系,验证了企业数字化转型对提升出口国内附加值率的影响及其作用机制。研究的主要结论包括:企业数字化转型显著提升了出口国内附加值率,主要通过优化人力资本结构、提高生产率和增强创新能力三个途径实现。针对不同类型企业的异质性分析显示,在非劳动密集型企业、一般贸易企业、国有企业及数字经济发展水平较高的地区,企业的数字化转型对提升出口国内附加值率的效果在统计学上显著。研究结论为推进企业的数字化转型和促进中国企业向全球价值链高端迈进提供了微观证据和决策依据。The comprehensive development of digital technology and its deep integration into enterprise operations have become critical factors for businesses exploring new growth opportunities and enhancing their position in the global value chain division of labor.Based on data from Chinese listed companies and the Chinese customs database,the impact of enterprise digital transformation on increasing domestic value-added export rates and its operational mechanisms was verified.Key findings of the research include:digital transformation significantly enhances the domestic value-added export rates of enterprises,primarily through optimizing human capital structure,improving productivity,and enhancing innovation capabilities.Heterogeneous analysis across different types of enterprises shows that in labor-intensive enterprises,general trade enterprises,state-owned enterprises,and regions with higher levels of digital economic development,the effect of digital transformation on increasing domestic value-added export rates is statistically significant.These research conclusions provide micro-level evidence and a decisionmaking basis for advancing enterprise digital transformation and promoting Chinas enterprises towards higher tiers of the global value chain.
