知识的吸收能力对企业的创新绩效起重要作用，企业的知识基础理论认为组织只有不断地自行发展和吸收外部社会资本以提升自己的创新绩效才能维持持续的竞争优势。本文以企业的知识理论为理论基础，对205个样本进行实证分析，探讨在知识吸收能力的中介效应下，企业社会资本对创新绩效的影响。实证研究结果表明：知识吸收能力对企业创新绩效的影响呈正相关关系；企业社会资本的外部横向关系资本与纵向关系资本对创新绩效的影响呈正相关关系；斜向关系资本对企业创新绩效的直接影响呈U型关系；在吸收能力与社会资本的交互作用下，横向与纵向社会资本与创新绩效的正相关性加强；斜向关系资本与创新绩效由U型关系转化为显著的正相关关系。本论文研究结论对企业如何利用社会资本提高创新绩效提供了建议与参考

The absorptive capacity of knowledge plays an important role in corporation’s innovation performance. Corporation’s knowledge basic theory thinks that organizations only constantly develop and absorb the external social capital to improve their innovation performance, and in this way, it can maintain the sustaining competitive advantage. Based on corporation’s knowledge basic theory, this paper makes an empirical analysis of 205 samples, and explores corporate social capital's impact on innovation performance under the mediation effect of knowledge’s absorptive capacity. Empirical study results show that: (1) there is positive correlation between the knowledge’s absorptive capacity and corporation’s innovation performance; (2) the transverse and vertical relationship capital of corporate social capital is positively correlated with innovation performance; the direct impact of oblique relationship capital on corporation’s innovation performance is U shape (3) there is positive correlation between the three dimensions of social capital ( transverse, vertical and oblique relationship capital) and knowledge’s absorptive capacity; (4) the knowledge’s absorptive capacity plays a part role of mediation effect between corporate social capital and innovation performance. This paper studies provide suggestions and reference for corporation on how to use social capital to improve innovation performance.
