新产品开发是一种知识密集型活动，成功的新产品开发离不开高效的知识管理。在知识融合的背景下，企业如何优化知识管理决策以提升新产品开发绩效，正是本项目要回答的问题。本项目基于创新搜索视角提出知识网络对新产品开发绩效影响的整合性理论模型：首先，分析知识网络的演变以探究知识整合与配置的动态性，探究知识网络对企业新产品开发绩效的直接作用机理以剖析知识整合与配置在新产品开发过程中的重要性；其次，提出以创新搜索策略为中介作用的知识网络对新产品开发绩效的间接影响模型，以厘清知识整合与配置、创新搜索在新产品开发过程中的作用关系；最后，探寻“知识网络—创新搜索策略—新产品开发绩效”模型中的权变因素，以回答企业如何根据内外部特征优化知识整合与配置、创新搜索策略从而实现新产品开发绩效提升的问题。本项目的成果将丰富知识基础观下的新产品开发绩效研究，为我国企业开展高效的知识管理进而提升新产品开发绩效提供参考建议。

New product development belongs to the knowledge-intensive activity. Successful new product development cannot be separated from efficient knowledge management. Under the background of knowledge convergence, how to improve the performance of new product development through effective knowledge management is the question to be answered by this project. Based on the innovative search perspective, this project proposes the integrated theoretical model of the effect of firms’ knowledge network on the performance of new product development. Firstly, this project aims to analyze the evolution of knowledge network to reveal the dynamic nature of knowledge integration and configuration (KIC), and the direct effect of knowledge network on firms’ new product development performance in order to explore the importance of KIC in the process of new product development. Secondly, this project plans to discuss the indirect effect of knowledge network on the new product development performance mediated by the innovative search pattern in order to clarify the relationship between KIC and innovative search in the process of new product development. Finally, this project tries to explore the contingent factors in the “Knowledge network-Innovative search pattern-New product development performance" model, in order to answer the question of how firms optimize the decisions of KIC and innovative search to improve new product development performance according to the internal and external environment. The results of this project will enrich researches on new product development in the knowledge base view, and provide reference suggestions for firms in China to carry out efficient knowledge management to improve the performance of new product development.
