知识是项目型组织(project-based organizations, PBOs)持续发展的关键资源，其有效地转移和共享不但有助于项目的成功，更有利于PBOs的长远发展。本研究运用多层线性模型，通过采集和分析来自中国建筑第*工程局有限公司的480个项目型组织样本问卷数据，探讨组织情景对项目型组织成员知识转移动机和知识转移效果的跨层次影响。结果表明：知识转移动机是决定知识转移行为的关键所在；组织情境差异化影响成员的知识转移动机和知识转移效果。这一发现揭示了组织情景影响成员知识动机和知识转移效果的内在机理，拓展了主流文献的相关研究，并为项目型组织知识管理实践提供借鉴。

knowledge is a key resource in the project-based organizations, and its transfer or share not only effectively contribute to the successful of the project but more conducive to the long-term development of PBOs. In this study, hierarchucal linear model was used to analyze the organizational contex how to cross level impact on member’s knowledge transfer motivation and knowledge transfer effect in project-based organization by collecting and analyzing the 480 sample questionnaire data from China Construction Suilding(Group) Corporation limited. The results show that the motivation of knowledge transfer is the key factor to determine the behavior of knowledge transfer; the organizational context take a different influence for motivation and effection of knowledge transfer. The findings reveal the intrinsic mechanism of organizational context how to influence the motivation and effection of knowledge transfer, which will extends related research of mainstream literature and provide a reference for knowledge management in PBOs.
