摘　　要：文章基于专利引用网络构建企业层面数实产业技术融合指标,从理论和实证两个方面深入探讨了数实产业技术融合对我国企业全球价值链稳定性的影响及其作用机制。研究结果表明,企业进行数实产业技术融合能显著提升其全球价值链的稳定性。融合垂直深度越深、水平广度越广,这一“稳链”作用越明显。机制分析表明,企业通过数实产业技术融合能够扩大出口产品范围、优化进口中间品布局策略及拓展专利知识宽度,从而提升我国企业全球价值链的稳定性。在异质性分析层面,数实产业技术融合对企业全球价值链稳定性的影响在具有不同内部特征和外部环境的企业中存在明显差异。文章为新时代促进数字新质生产力与实体产业的深度融合、提升企业全球价值链稳定性提供了实证支持与政策指引。This paper constructs an enterprise-level indicator for technological integration of digital industries and real industries based on patent citation network,and deeply explores the impact and mechanism of technological integration of digital industries and real industries on the global value chain(GVC)stability of China's Enterprises from both theoretical and empirical perspectives.The research results show that technological integration of digital industries and real industries can significantly enhance the GVC stability of the enterprises.The impact of technological integration of digital industries and real industries on the GVC stability will be more significant when the integration depth is deeper and the integration breadth is broader.The mechanism analysis reveals that the enterprises can expand the range of export products,optimize the layout strategy of imported intermediate goods and expand the patent knowledge breadth through technological integration of digital industries and real industries,thereby enhancing the GVC stability of China's enterprises.In terms of heterogeneity analysis,the impact of technological integration of digital industries and real industries on the GVC stability of the enterprises varies significantly among the enterprises with different internal characteristics and external environments.The paper provides empirical support and policy guidance for promoting the deep integration of digital new quality productive forces and real industries,and enhancing the GVC stability of the enterprises in the new era.
