在竞争日益激烈的当代社会，家庭-工作关系无论对个人还是对企业来说，都显得越来越为重要。本研究以零售业的员工为例，通过一个全国范围内的大样本研究，探讨了家庭-工作关系的两个基本表现形式，即家庭-工作冲突和家庭-工作增益对于员工工作投入、工作绩效的关系。结果发现，家庭-工作冲突与工作投入呈负相关，与工作绩效的相关不显著；而家庭-工作增益则与工作投入的三个维度和工作绩效呈正相关。 进一步的中介分析发现，工作投入可以中介家庭-工作增益与工作绩效之间的关系。 这些结果深化了对家庭-工作关系与工作绩效之间的关系的认识，对当下中国日益增加的家庭-工作关系问题的应对提供了实践指导依据。

Family-work relationship is becoming more and more important in modern China. In this research, we examined the relationships between family-work relationship, work engagement and work performance in a large sample recruited from various cities in China. In doing this, we distinguished between family-work conflict and family-work enrichment. Results showed that family-work conflict was negatively correlated with work engagement and was not related with work performance, while family-work enrichment was positively correlated with these outcomes. Moreover, mediation analysis showed that work engagement mediated the relationship between family-work enrichment and work performance. These findings extend the understanding of the influences of family-work relationship on work engagement and work performance. Practically, these findings may help coping with the increasing family-work relationship issues.
