中文摘要：

将知识特性、知识提供方特性、知识接受方特性、知识提供方与知识接受方合作关系特性、知识共享环境特性作为航天型号研制过程中知识共享的影响因素．以知识水平提升程度和型号研制能力提升程度作为知识共享绩效评价标准，建立理论关系模型并进行了实证分析。结果表明：知识特性、知识提供方特性、知识接受方特性、合作关系特性、环境特性5因素对知识共享有显著影响，而知识提供意愿、地理距离、文化氛围、保密制度对知识共享的影响作用不显著。提出了促进航天型号研制知识共享的对策。

英文摘要：

This research blueprints a theoretical module and carries out an empirical study by taking knowledge characteristics, knowledge provider characteristics, knowledge recipient characteristics, cooperative relation characteristics, and knowledge sharing environmental characteristics as the influencing factors during the research and development of aerospace products and using the upgrade of knowledge and advancement in product research and development as the evaluation criteria for knowledge sharing performance. The study result shows that the above mentioned five influencing factors affect knowledge sharing prominently while other factors, such as knowledge providing intention, geographical distance, cultural atmosphere, and secrecy regime, have little influence on knowledge sharing. Based on that, the author puts forward strategies to facilitate knowledge sharing in the course of aerospace product research and development.
