摘要：经济发展和社会变迁在加速城镇化进程的同时，也加速了人们熟悉的故乡的消逝，乡愁成为普遍的社会现象，其对员工适应性绩效的影响已成为管理实践面临的重要问题。本研究遵循扎根理论的研究方法，深入探究乡愁对员工适应性绩效的作用机理并构建理论模型。研究发现：(1)乡愁会促使员工表现出工作过度和工作退缩的行为倾向；(2)工作退缩削弱员工的适应性绩效，而工作过度则对员工适应性绩效具有“双刃剑”效应；(3)组织积极情感基调缓解乡愁对员工工作退缩和工作过度的影响，而组织消极情感基调则强化上述影响。本研究揭示了乡愁对员工适应性绩效的影响路径，深化了乡愁的理论内核，并为组织管理实践提供了重要启示。

Abstract: While economic development and social changes are accelerating the process of urbanization, they are also accelerating the disappearance of people's familiar hometowns. Homesickness has become a common social phenomenon, and its impact on employees' adaptive performance has become an important issue of management practice. This study follows the research method of grounded theory, deeply explores the mechanism of homesickness on employees' adaptive performance and constructs a theoretical model. Research has found that: (1) Homesickness will prompt employees to exhibit overwork and work withdrawal behavioral tendencies. (2) Work withdrawal weakens employees' adaptive performance, while overwork has a "double-edged sword" effect on employees' adaptive performance. (3) Organizational positive affective tone alleviates the impact of homesickness on employees' work withdrawal and overwork, while organizational negative affective tone strengthens the above effects. This study reveals the path of impact of homesickness on employees' adaptive performance, deepens the theoretical core of homesickness, and provides important inspiration for organizational management practice.
