在大多数权威的中外管理教课书上,学者们的注意力主要放在正式的组织结构、信息流动、授权等领域。本文则从总结非正式组织研究的起源、定义、作用入手,探讨了非正式组织成因及与正式组织的关系,最后结合组织管理研究分析指出非正式组织并不是组织中的“余缺问题”,而应当被作管理中比较“契约”和“科层”的第三种控制/合作机制。 In most of the authoritative teaching books both at home and abroad, scholars’ attention is mainly in the areas of formal organizational structure, information flow, and authorization. This article starts with the summary of the origin, definition and function of informal organization research, discusses the causes of informal organization and its relationship with formal organizations. At last, it analyzes that the informal organization is not the “remaining problem” in the organization. It should be the third control / cooperation mechanism in management that compares “deeds” with “bureaucratic levels.”
