基于36个国家2014—2021年16个服务行业“国家-行业-年份”三维面板数据,实证分析了服务业数字化投入对服务业全球价值链分工的影响效应和机制效应。研究表明:数字化投入对服务业全球价值链分工具有显著的正向影响;经过稳健性和内生性检验之后,结论依然成立;从数字核心行业的投入异质性来看,电气和光学业的投入数字化对服务业全球价值链分工的正向促进作用大于金融中介业大于邮政和电信业;从服务业行业的异质性来看,数字化投入对生产性服务业全球价值链分工的促进作用大于生活性服务业;进一步分析结果表明,数字服务贸易限制对数字化对服务业全球价值链分工具有逆向调节作用,且其子指标数字化服务的其他贸易壁垒和电子支付系统的逆向调节效应更大。
