基于生态学态势理论，以2015~2023年1 459家制造业上市企业的面板数据为样本，从知识基础观的角度探究了企业生态位对创新溢出效应的影响机制。研究表明：企业生态位的两维度特征，即生态位位态和生态位位势对创新溢出效应具有正向影响；知识耦合在企业生态位两维度与创新溢出效应间发挥中介作用；资源依赖负向调节企业生态位位势与创新溢出效应的关系。

Based on the ecological situation theory and the knowledge-based view, this study uses panel data from 1459 listed manufacturing enterprises from 2015 to 2023 to explore the mechanism of the impact of enterprise niche on innovation spillover effects. The findings reveal that the two-dimensional characteristics of enterprise niche-niche state and niche potential-exert a positive impact on innovation spillover effects. Furthermore, knowledge coupling acts as a mediator between these two niche dimensions and innovation spillover effects. Additionally, resource dependence is found to negatively moderate the relationship between niche potential and innovation spillover effects.
