26作为优质中小企业的核心力量，专精特新“小巨人”企业不仅具备突出的创新实力，也是以点带链、助推产业链强链的关键主体。本文将新三板挂牌中小企业作为主要研究对象，借助国家级专精特新“小巨人”分批认定政策来构造准自然实验，采用多期双重差分模型探究了“小巨人”资质认定的供应链创新溢出效应。研究发现，“小巨人”资质认定能够通过资源效应、竞争效应和示范效应三重机制，显著促进其链上企业增强创新实力。进一步分析表明，该创新溢出效果因供应链主体和关系特征而异，当焦点企业替代性较弱、链上企业吸收能力较强以及供应链关系稳定性较高、交易强度较大、地理距离较近时，焦点“小巨人”企业发挥的创新外溢作用更突出。此外，“小巨人”资质认定还能对更高阶链上企业产生创新溢出效应。本文捕捉了“小巨人”沿供应链释放的“大能量”，既明晰了创新“正外部性”的供应链传播机理，也为政府着力构建中小企业梯度培育格局提供了实践启示。
