数字化转型下供应链网络结构、关系特征与企业技术创新绩效OACHSSCD

Against the backdrop of the accelerating global digital transformation wave and persistent corporate innovation challenges,unlocking innovation potential through optimizing supply chain network structure has become a critical issue for enhancing core competitiveness.Based on 4 204 observations from Shanghai and Shenzhen A-share listed companies spanning 2015-2023,this study empirically analyzes the impact of supply chain network characteristics and relationship characteristics on corporate technological innovation performance and explores the moderating mechanism of digital transformation.The findings reveal that betweenness centrality and structural hole richness significantly promote tech-nological innovation performance,while the clustering coefficient exhibits a U-shaped relationship with innovation performance,and relationship strength demonstrates an inhibitory effect.Further analysis in-dicates that digital transformation strengthens the promoting effects of betweenness centrality and struc-tural holes on technological innovation and significantly moderates the U-shaped relationship of the clustering coefficient,making it flatter;however,its moderating effect on the negative impact of relation-ship strength is limited.Mechanism tests show that digital transformation enhances the enabling effect of network structure on technological innovation through three pathways:improving information transparen-cy,expanding knowledge integration channels,and enhancing network responsiveness.By examining both structural and relational dimensions of the supply chain network,this study reveals the internal mechanisms through which digital transformation influences corporate technological innovation,provi-ding theoretical foundations and practical insights for optimizing supply chain layout and building col-laborative innovation ecosystems in the digital context.
