摘要: 打造具有更强创新力的产业链供应链是“十四五”时期及未来更长时期的重要战略任务。基于上市公司供应链创新数据,从理论和经验上深入探究供应商创新对下游客户创新的影响。研究结果显示,第一,供应商在创新能力上相比下游客户具有一定的领先优势,体现为供应商的发明专利申请时间整体早于下游客户,并且在高度依赖创新驱动的行业中发明专利数量更多。第二,供应商创新具有显著的溢出效应,有效地推动了下游客户的创新产出。经过一系列内生性检验和其他稳健性检验,这一结论依然成立。第三,供应商创新有助于促进知识溢出、增加合作创新以及提升下游客户的研发效率,从而促进下游客户创新产出的增加。第四,供应商创新具有明显的经济效益,能够显著地提升下游客户的公司价值和成长性。上述研究发现有助于深化对企业创新和供应链合作的理解,同时为促进我国供应链的整合和创新能力的提升提供政策参考。

Abstract: Building a supply chain with strong innovation capabilities is a crucial strategic task for China during the “14th Five-Year Plan” period and beyond. Based on the data of supply chain innovation from listed companies, this study delves into the impact of supplier innovation on downstream customer innovation from both theories and experiences. The main findings are as follows: Firstly, suppliers have a certain leading advantage in innovation ability compared to downstream customers, which is reflected in the fact that their invention patent application time is generally earlier than that of downstream customers, and they have a higher number of invention patents in industries highly dependent on innovation driven development. Secondly, supplier innovation demonstrates significant spillover effects, significantly increasing the innovation output of downstream customers. After a series of endogeneity tests and other robustness tests, this conclusion still holds. Thirdly, supplier innovation contributes to promoting knowledge spillover, increasing cooperated innovation and enhancing the R&D efficiency of downstream customers, thereby increasing their innovation output. Fourthly, supplier innovation yields significant economic benefits, boosting the corporate value and growth prospects of the downstream customers. The above findings contribute to a deeper understanding of corporate innovation and supply chain collaboration, at the same time, offering new policy insights to promote the integration of supply chains and enhance innovation capabilities in China.

Key words: supply chain, innovation, spillover effects, downstream customer
