中文摘要：

把科研团队的生命周期划分为初创期、成长期、成熟期、衰退期或蜕变期四个阶段。运用案例研究方法探讨科研团队不同生命阶段的特点。在综合三个案例分析结果的基础上提炼出如下结论：初创期,科研团队的领导者是团队发展的规划者与团队成长的指导者,团队初步建立了外部沟通机制,团队文化呈现出参与和协商、和谐与个性自由等特征;成长期,领导者是团队激励者与团队沟通的垂范者,团队建立了定期沟通机制,在激励与奖惩机制上有所发展,团队文化呈现出鼓励个体的主动性和自主权、公平活跃的工作环境等特点;成熟期,团队领导是团队发展的再规划者与新生力量的培养者,团队有良好的管理体制,有规范化的工作程序和工作场所,成员习惯按照既定规章办事;衰退期或蜕变期,团队的创新精神渐渐弱化,管理与领导方式僵硬等。
