摘　　要：在新质生产力培育背景下,数字技术创新在全球价值链体系中发挥着日益关键的作用。通过分析中国工业企业的数字技术专利数据,本文探讨了数字技术创新如何影响企业出口产品质量升级。研究发现,数字技术创新显著促进了企业出口产品质量的提升,这一结论在采用不同方法的稳健性检验中均得到验证。渠道分析表明,数字技术创新通过推动创造性破坏、强化出口稳定性和促进数字产品进口多样性驱动企业出口产品质量升级。进一步地,数字技术创新在研发网络和供应链网络中存在显著的溢出效应。异质性分析表明,数字技术创新的作用在位于较强知识产权保护地区的企业、数字技术创新质量较高的企业、以质量竞争策略参与出口竞争的企业、采用合作研发模式的企业、向数字经济弱国出口的企业、处于产业数字化行业的企业及企业非核心出口产品的样本中更为突出。这些结论可为以数字技术创新助力推进贸易强国建设、增强产业链供应链安全稳定提供参考。Under the background of cultivating new quality productive forces,digital technology innovation has played an increasingly crucial role in the development of global value chain.This paper shows that digital technology innovation significantly promote the upgrading of export product quality,and it is robust after replacing variable measurement method,adding stricter fi xed eff ects,eliminating extreme samples,using lag eff ect test and PSM-DID test,adopting instrumental variables and IV-2SLS.The channel analysis shows that digital technology innovation drives the upgrading of export product quality by promoting creative destruction,strengthening export stability,and promoting the diversity of digital product imports.Further,there are signifi cant spillover eff ects of digital technology innovation in R&D networks and supply chain networks.The heterogeneity analysis shows that the role of digital technology innovation is more prominent in the samples of enterprises located in areas with strong intellectual property protection,enterprises with higher quality of digital technology innovation,enterprises participating in export competition with quality competition strategy,enterprises adopting cooperative R&D model,enterprises exporting to countries with weak digital economy,enterprises in industrial digitalization industry,and enterprises’the export quality non-core products.The article provides research reference for promoting the construction of a strong trading nation and enhancing the security and stability of industrial and supply chains through digital technology innovation.
