基于社会信息加工理论，通过对来自多个知识型企业一线员工的514份三阶段追踪调查数据的实证分析，探究了平台型领导抑制员工知识隐藏行为的心理安全感和情感承诺双路径过程模型，以及上下级匹配在其中的调节作用。研究结果表明：平台型领导通过提升知识型员工的心理安全感和情感承诺，显著降低其知识隐藏行为；上下级匹配在上述过程中起到了正向调节作用，即上下级匹配度较高时，上述间接效应更强，反之则更弱。

Drawing on social information processing theory, through the analysis of three-wave data (including 514 valid samples from front-line knowledge workers in knowledge-based enterprises), this study investigates a dual process model, which encompasses both psychological safety and affective commitment mechanisms, to reveal how platform leadership inhibits employees’ knowledge hiding. It also examines the moderating role of person-supervisor fit. The results indicate that, platform leadership significantly enhances knowledge employees’ psychological safety and affective commitment, thereby effectively reducing their engagement in knowledge hiding behavior. In addition, person-supervisor fit positively moderates the indirect effect of platform leadership on knowledge hiding through psychological safety and affective commitment, that is, when the degree of fit between superiors and subordinates is high, the above-mentioned indirect effects are stronger, and vice versa.
