党的十八大以来，党政部门改革采取大部制的总体思路，很多职能部门被撤并。如何解释部门的终结是组织研究的重要问题。本文以40多年来广州市流动人口管理中的组织变迁为例，完整呈现这一领域的地方政府部门从产生到常规化，再到撤并的历程，并从技术和任务两个维度形成创新性分析框架。研究发现，随着治理任务从管理型向服务型转型，“高效办成一件事”的逻辑超越了部门逻辑。在交互式大数据信息平台和App支持下，综合性的平台型组织兴起，而提供单一服务型任务的职能部门存在着被撤并的可能性。

Since the 18th CPC National Congress, the Party and government institutional reforms have adopted overarching approach centered on the larger government departments, leading to the consolidation or abolition of many functional departments. Explaining "the end of departments" is an important issue in organizational studies. Taking the organizational transformation in migrant population management in Guangzhou over the past four decades as a case study, this paper comprehensively traces the trajectory of local government departments in this field from their emergence and institutionalization to their eventual consolidation. An innovative analytical framework is developed along the dimensions of technology and tasks. The study reveals that as governance tasks shift from regulation to service provision, the logic of efficient completion of specific tasks supersedes departmental logic. Supported by interactive big data platforms and Apps, comprehensive platform-based organizations emerge. Functional departments responsible for singular service tasks face the potential for abolition or consolidation.
