基于压力认知评价理论，通过对三阶段350份问卷数据的分析，探究了知识距离对年长员工向年轻同事知识寻求的作用机制和边界条件。研究结果表明：知识距离通过阻碍性评价抑制年长员工向年轻同事知识寻求；知识距离通过挑战性评价促进年长员工向年轻同事知识寻求；年龄包容型人力资源负向调节知识距离与阻碍性评价之间的关系，继而削弱阻碍性评价的负向中介效应；年龄包容型人力资源正向调节知识距离与挑战性评价之间的关系，进而增强挑战性评价的正向中介效应。

Drawing on the cognitive appraisal theory of stress, through the analysis of three-stage questionnaire data from 350 samples, this study examines the mechanisms and boundary conditions through which knowledge distance influences older employees’ knowledge seeking from younger colleagues. The results show that knowledge distance inhibits older employees’ knowledge seeking from younger colleagues through hindrance appraisal, while it facilitates such knowledge seeking through challenge appraisal. Moreover, age-inclusive human resources practices negatively moderate the relationship between knowledge distance and hindrance appraisal, thereby weakening the negative mediating effect of hindrance appraisal. In addition, age-inclusive human resources practices positively moderate the link between knowledge distance and challenge appraisal, thereby strengthening the positive indirect effect via challenge appraisal.
