摘　　要：数字服务贸易开放是赋能贸易高质量发展的重要举措,更是促进高技术制造业全球价值链升级的核心所在。文章基于2012—2022年高技术制造业A股上市公司的数据,运用多元线性回归模型和中介效应模型,探讨了数字服务贸易开放与高技术制造业全球价值链升级之间的关系。研究结果表明,数字服务贸易开放能有效推动高技术制造业全球价值链的升级。传导机制检验显示,数字服务贸易开放可从创新层面增加创新产出与创新投入、从产业层面推动产业结构合理化与产业结构高级化,进而赋能高技术制造业全球价值链升级。异质性分析结果表明,在资本密集型与高一体化程度样本中,数字服务贸易开放对高技术制造业全球价值链升级的赋能作用更为显著。进一步的检验表明,数字服务贸易开放对中国高技术制造业全球价值链升级的影响具有持续性。The opening-up in digital service trade is not only an important measure to enable the high-quality development of trade,but also the core of promoting the upgrading of the global value chain of high-tech manufacturing industry.Based on the data of A-share listed high-tech manufacturing companies from 2012 to 2022,this paper uses multiple linear regression model and intermediary effect model to study the relationship between the opening-up of digital service trade and the upgrading of the global value chain of high-tech manufacturing.The research results show that the digital service trade opening-up can effectively promote the upgrading of the global value chain of high-tech manufacturing.The transmission mechanism test reveals that the opening-up in digital service trade can increase innovation output and innovation input at the innovation level and promote the rationalization of industrial structure and the upgrading of industrial structure at the industrial level,and then enable the upgrading of the global value chain of high-tech manufacturing.Heterogeneity analysis results show that in the capital-intensive and highly integrated samples,the opening-up in digital service trade has a more significant promoting effect on the upgrading of the global value chain of high-tech manufacturing.Further tests show that the opening-up in digital service trade has a sustained impact on the upgrading of the global value chain of China's high-tech manufacturing industry.
