摘　　要：文章从信息成本和边际成本的视角出发,探讨了数字产品进口对企业技术创新的影响。研究结果表明,数字产品进口显著提升了企业专利申请的质量和数量,并促进了供应链上下游企业的协同创新。具体而言,数字产品进口通过降低企业的边际成本、改善企业间信息不对称以及技术溢出来有效促进企业创新。异质性分析显示,数字产品进口对人力资本和生产率较高的企业具有更强的创新激励效果。拓展性分析指出,数字产品进口对发明专利数和实用新型专利数的增加具有更强的促进作用,有助于企业实现实质性和原理性的创新变革。此外,与数字产品进口数量的上升相比,数字产品进口质量的提升对企业创新的促进效果更为显著。文章的研究有助于全面理解数字产品进口与企业技术创新之间的关系,并为中国利用数字贸易实现创新驱动提供了重要的政策启示。Based on the Statistical Classification of the Digital Economy and its Core Industries(2021) by the National Bureau of Statistics of China and the ICT products classification by the United Nations Conference on Trade and Development,this paper manually collates the 6-digit HS codes for digital products to obtain information on the digital products imported by enterprises.From the perspectives of information cost and marginal cost,this study examines the impact of digital product imports on firms' technological innovation.The findings indicate that digital product imports significantly enhance both the quality and quantity of firms' patent applications and promote collaborative innovation along the supply chain.Specifically,imports of digital products effectively promote firms' innovation by lowering their marginal costs,reducing information asymmetries between firms,and facilitating technological spillovers.Heterogeneity analysis reveals that digital product imports have a stronger innovation incentive effect on firms with higher human capital and productivity.Furthermore,expansive analysis highlights that digital product imports more significantly promote the increase in invention and utility model patents,facilitating substantive and principled innovation.Additionally,improvements in the quality of digital product imports have a more pronounced effect on fostering innovation than an increase in the quantity of imports.This research provides a comprehensive understanding of the relationship between digital product imports and firms technological innovation,offers critical policy insights into how China can leverage digital trade to drive innovation.
