多团队系统（MTS）是当前重大科技项目实现跨组织合作、协同增效的重要组织形式。课题以MTS中的边界管理者为切入点，在明确区分其扮演MTS成员和MTS子团队领导角色形成的双重心理契约的基础上，探究边界管理者双重心理契约及其组合对重大科技项目MTS绩效的影响机制。主要研究：（1）重大科技项目MTS中边界管理者双重心理契约识别；（2）边界管理者双重心理契约对MTS绩效的独立作用机制；（3）边界管理者双重心理契约组合对MTS绩效的复合作用机制；（4）基于边界管理者心理契约的重大科技项目MTS绩效提升策略。课题通过重大科技项目案例分析、纵向追踪调查和实验室模拟实验，挖掘边界管理者双重心理契约作用过程中的关键中介变量，阐明边界管理者双重心理契约发挥作用的边界条件，既可为MTS绩效提升目标下边界管理者心理契约设计和管理提供理论依据，也可为构建充分发挥边界管理者积极作用的重大科技项目绩效保障机制指明方向。

Multi-team system (MTS) has been an important organizational form in major science and technology projects for its advantage of facilitating cross organization cooperation and synergism. This study focuses on the boundary spanner in MTS. Based on the acknowledgment of the dual psychological contracts of boundary spanner, as MTS members and as MTS component team leaders respectively, the study explores how the dual psychological contracts with their combination impact the MTS performance in major science and technology projects. The main contents are as follows: (1) identifying the dual psychological contracts of MTS boundary spanner in major science and technology projects; (2) working mechanism of each of the two particular psychological contracts on MTS performance; (3) working mechanism of the combination of the dual psychological contracts on MTS performance; (4) MTS performance improvement strategies in major science and technology projects based on the psychological contracts of boundary spanner. The methodology of this study contains case study on major science and technology projects, longitudinal tracking investigation and experimental simulation within laboratory environment. As the roles of key mediators in the process of dual psychological contracts of boundary spanner are identified, and as the boundary condition of the dual psychological contracts is articulated, the study is importance both on contract design and management for boundary spanners in purpose of MTS performance improvement, and on institutional build-up in major science and technology projects for fully activating boundary spanners.
