Abstract: The concept of successful aging at work (SAW) offers new insights for organizations seeking to develop their elderly human resources. However, existing studies have yet to conceptualize SAW clearly, neglected the influence of intergenerational factors, and little attention was paid to its outcome variable. To address these research gaps, we have scheduled to conduct three correlated studies: Study 1 schedules to draw on the perspective of intergenerational interaction and re-explore the concept and dimensions of SAW. Study 2 plans to examine the relationship between intergenerational knowledge sharing and SAW, and further reveal the dual-path mediation mechanism of occupational adaptability and intergenerational friendship, based on the perspectives of person-fit theory. Moreover, the Actor-Partner Interdependence Model was constructed to test the actor and partner effects of intergenerational knowledge sharing on SAW. Study 3 will draw on the cognitive appraisal theory of stress to investigate the double-edged sword effect of SAW on younger employees’ work engagement. In conclusion, we adopt a novel perspective-intergenerational interaction perspective, to elucidate the impact of intergenerational knowledge sharing on SAW and its underlying mechanisms. Furthermore, we extend the investigation of the consequences of SAW, thereby contributing to the theoretical framework of SAW and promoting organizational diversity management.we attempt to explore the concept and dimensions of SAW; 2) we first examine the relationship between intergenerational knowledge sharing and SAW, and further reveal the dual-path mediation mechanism of occupational adaptability and intergenerational friendship, based on the perspectives of person-fit theory.

We draw on a new perspective-intergenerational interaction perspective and reveal the influence of intergenerational knowledge sharing on SAW and its mechanism, and extend the research on its consequences, which contributes to improving the theoretical framework of SAW and promoting organizational diversity management.
