The previous researches in the work-family interface were mainly from the perspective of work-family conflict, while the most recent studies have started to explore the positive relationship between work and family. Indeed, researchers have increasingly examined positive relationships between work and family lives by developing some concepts such as work-family enhancement, work-family positive spillover, work-family facilitation and work-family enrichment. Work-family enrichment is defined as how work and family benefit from each other and emphasizes the spillover of resources between the work and family roles, in consequence to affect an individual’s performance and life quality in both roles. There has been much research on work-family enrichment, however, previous research on the impacts of role resource on work-family enrichment discussed less about individual perception and the change of psychological state and ignored that the enrichment level can also be affected by work-family boundary features. Based on that, this study emphasized on aspects below:①By integrating the exiting literature, this paper proposed the main logic line under the mechanism above, which was “role resource accumulation---psychological change--- cross-domain enrichment---role evaluation and engagement”, and also constructed the role resources cross-domain enrichment model. As the precondition of work-family enrichment, role resource accumulation is the foundation of the entire logical mainline. ②Role resources (work-related resources, organizational-related resources, and family-related resources) acquisition relies on the organization and family climate, this study discussed the direct relationship between role resources and work-family enrichment. The circular accumulation of resources serves as a safeguard to the work-family enrichment and cross-domain enrichment as well as is the guarantee for resource accumulation. ③Cross-domain enrichment is generated in the psychological process of individual perception and gain of role resources. This article also pointed out the indirect relationship between role resource accumulation and work-family enrichment, through change of psychological factors. The individuals have difference in perception and accumulation of role resources that can give rise to the individual role cognition and the change of the psychological state. Work and home resources increase personal resources. ④The enrichment level is affected by work-family boundary features, individual features and domain features. The degree of work-family boundary strength affected cross-domain enrichment, suggesting that different levels of boundary strength might moderate the relationship between psychological resources and work-family enrichment. Specifically speaking, the stronger the boundary between work and family is, the less enrichment happens cross domains. To sum up, we suggested few directions about work-family enrichment for the future studies in the end. ①The model showed that individuals’ perceptions and accumulation of role resources affect work family enrichment through psychological resources. Therefore, future studies could discuss the gain and loss cycles of role resources over time and explore dynamics of the relationships among work and family resource gain and loss, work-to-family enrichment over time.②Future studies could also try to explore the influencing mechanism, in which accumulation of role resources affect role evaluation and psychological factors, in turn influence work-family enrichment. ③In order to generalize the model in a broaden way, it is necessary to add moderation effects such as individual characteristics, domain features and work-family boundary features and so on. The culture factors should also be taken into account. It will be necessary for future studies to introduce the local cultural situation variables to enrich the comparative study on work-family enrichment.
