供应链的创新溢出效应研究——来自A股市场的经验证据

Research on the Innovation Spillover Effect of Supply Chain:Empirical evidence from A-share market

从创新溢出视角出发,以2008—2019年A股市场非金融类上市公司为样本,利用双向固定效应模型实证考察供应链的创新水平差异对企业创新的影响。结果发现供应链的创新水平与企业创新呈显著正相关关系,说明企业的供应商与客户的创新水平越高,企业自身创新水平也显著更高。上述结论在进行倾向得分匹配(PSM)控制内生性问题后依然成立。据此提出有关进一步推动供应链创新与应用、强化供应链创新溢出的策略建议。

From the perspective of innovation spillover,taking the non-financial listed companies in the A-share market from 2008 to 2019 as samples,the two-way fixed effect model was used to empirically study the impact of innovation level differences in the supply chain on enterprise innovation.The results show that there is a significant positive correlation between the innovation level of supply chain and enterprise innovation,indicating that the higher the innovation level of suppliers and customers,the higher the innovation level of enterprise itself.The above conclusion is still valid after the control of endogenous problems by propensity score matching(PSM).Based on this,puts forward some strategic suggestions to further promote the innovation and application of supply chain and strengthen the innovation spillover of supply chain.
