基于2010～2022年我国A股上市企业数据，探究供应链网络中企业双元创新同群效应。研究发现，供应链网络中企业开发式创新决策与探索式创新决策均存在同群效应，且表现为不同的行为特征差异。调节效应显示，供应链网络关系嵌入正向调节开发式创新的同群效应，负向调节探索式创新的同群效应；供应链网络结构嵌入正向调节探索式创新的同群效应。异质性分析表明，开发式创新同群效应在宏观环境不确定性较高时更为显著，探索式创新同群效应在宏观环境不确定性较低时更为显著，且开发式创新同群效应和探索式创新同群效应均在非国有企业、行业发展前景低迷的样本中更为显著。

Utilizing the data of China’s A-share listed enterprises from 2010 to 2022, this study constructs a cross-linked connection network based on supplier-customer relationships and examines the peer effect of enterprise ambidextrous innovation in the supply chain networks. It is found that both exploitative and exploratory innovation decisions exhibit peer effects within supply chain networks. Further research shows that the peer effect of enterprise ambidextrous innovation in supply chain networks exhibits different behavioral characteristics. From the perspective of enterprises’ own network characteristics, supply chain network relationship embedding positively moderates the peer effect of exploitative innovation and negatively moderates the peer effect of exploratory innovation. Supply chain network structure embedding positively moderates the peer effect of exploratory innovation. From the macro-environmental perspective, the peer effect of exploitative innovation is more significant when the macro environmental uncertainty is high, the peer effect of exploratory innovation is more significant when the macro environmental uncertainty is low. Both the peer effect of exploitative innovation and the peer effect of exploratory innovation are more significant in the samples of non-state-owned enterprises and in industries with sluggish development prospects.
