基于产业生命周期的视角,实证检验了企业内外关系网对创新绩效的正效应。结果显示随着产业阶段的推移,内部关系网对创新绩效的影响是先降后升的,而外部关系网则相反。在成长期和衰退期,企业内部关系网对创新绩效的贡献超过了外部关系网,成熟期的结论与之相反。 Based on the perspective of industry life cycle, this paper empirically tests the positive effect of internal and external network on innovation performance. The results show that with the development of the industrial stage, the impact of the internal network on innovation performance is the first to rise later, while the external network is the opposite. During growth and recession, the internal network of enterprises contributes more to the innovation performance than the external network, and the conclusion of the mature period is the opposite.
