Abstract: The "amphibians" who retain their peasant identity and travel between urban and rural areas for a long time begin to flow back, with the increasingly serious "hollowing out" of rural and the comprehensive promotion of rural revitalization strategy. In order to study the interactions between rural revitalization and labor back-flow, the push-pull theory is proposed to study the factors affecting labor back-flow under the background of rural revitalization strategy, as well as the internal logical relationship and response mechanism between them through using with the theory of rural sociology. Then, the study points out that rural revitalization and labor back-flow affect each other, and there is a virtuous circle between them. The former not only attracts the latter but also is promoted by the latter. At the same time, it is also affected by three different forces in the process of labor back-flow, namely:the pull of the countryside, the push of the city and the resistance of the "three rural" problems. Therefore, this paper puts forward suggestions for rural revitalization and guiding labor back-flow from three aspects, which are transforming the industrial development mode, optimizing resource allocation and implementing policy guarantee.
