摘要：工作重塑作为员工的一种主动性工作行为，关于其作用后果的研究一直以来都是学界备受关注的话题。关于工作重塑与工作投入之间关系的讨论还未达成一致，急需突破从单方面角度探讨的局限，且现有研究忽略了工作环境因素在其中的边界作用。本研究基于社会认同理论，通过一个情境实验和一个全模型问卷调研，全面考察了在不同程度的工作不安全感情境中员工工作重塑对其工作投入的双刃剑作用机制。研究结果表明：一方面，工作不安全感越弱，工作重塑对职业认同的正面影响越强，进而提高其工作投入；另一方面，工作不安全感越强，工作重塑对员工组织认同的负面影响越强，进而降低其工作投入。本文有助于辩证地理解工作重塑行为，在实践方面为组织有效进行工作重塑干预提供了有益启发。

Abstract: Job crafting is an active work behavior of employees, and the research on its consequences has always been a topic of concern in the academic community. However, the existing research on the relationship between work crafting and work engagement has not reached a consensus, ignoring the boundary role of work environment factors. It is urgent to break through the limitations of one-sided perspective. Based on social identity theory, this paper introduces job insecurity as a situational variable to investigate the double-edged-sword effect of job crafting on work engagement through a situational experiment and a comprehensive model survey. The results show that, on the one hand, the lower the job insecurity, the more positive impact of job crafting on professional identification, so as to improve work engagement; on the other hand, the stronger the job insecurity, the stronger the negative impact of job crafting on employees' organizational identification, thus reducing work engagement. This paper is helpful to dialectically understand job crafting behavior and provide useful inspiration for organizations to effectively implement job crafting intervention in practice.
