中文摘要：

如何平衡部门内探索式创新和利用式创新（双元创新）的矛盾，是管理实践和理论研究关注的重要主题。本文基于并行结构视角，运用社会网络理论和知识管理理论，分析了正式网络与非正式网络一致性对双元创新能力中探索式和利用式创新矛盾的平衡，并探讨了不同知识管理的调节作用。通过收集高新技术企业创新相关部门的实证数据进行分析，研究结果表明：部门正式互动或顺序工作流网络与非正式咨询网络的一致性与双元创新能力之间呈倒U型关系；知识交换与整合和知识冲突正向调节部门正式互动工作流网络与非正式咨询网络一致性与双元创新能力之间呈倒U型关系。说明适度重叠的部门正式互动或顺序工作流网络与非正式咨询网络能够有效平衡双元创新能力的矛盾，有效的知识管理能增强这一效果。该结论从社会网络视角细化了部门中并行结构自下而上实现双元创新能力的路径，并基于知识管理理论界定了并行结构实现双元创新的权变条件，也对企业借助正式与非正式网络一致性平衡探索与利用式创新的矛盾并形成双元创新能力具有重要指导意义。

英文摘要：

How to balance the contradiction between exploration innovation and exploitation innovation （ambidextrous innovation） in a department has become the hot subject for the business management theory and its practical research. From the parallel structure perspective, this paper applies social network theory and knowledge management theory to analyze how the consistency between formal and informal networks to balance the paradox between exploration innovation and exploitation innovation, and discusses the moderating role of different knowledge management. This paper collects the empirical data from innovation departments of high-tech enterprises to test the hypotheses. It comes to the conclusions as follows： firstly, the consistency between formal reciprocal/sequential workflow network and informal consulting network has an inverted U-shaped relationship with ambidextrous innovation; secondly, knowledge exchange ＆ combination and knowledge conflict have positively moderating effects on the relationship above. It shows that the appropriate overlap between formal reciprocal/sequential workflow network and informal consulting network can balance the paradox of ambidextrous innovation effectively, and efficient knowledge management can enhance this effect. The conclusion refine the path of achieving ambidextrous innovation from the bottom to up by parallel structure from a social network perspective, defines the contingency condition of achieving ambidextrous innovation by parallel structure based on knowledge management theory, and also has an important guide for enterprises to balance the contradiction between exploration innovation and exploitation innovation in a department and form ambidextrous innovation by the consistency between formal and informal networks in the future.
