Abstract: According to the connotation and extension of family life cycle theory, 456 micro-samples in Shaanxi area of Qinba Mountain Area were used to analyze the impact of family life cycle on farmers’ farmland transfer behavior by using statistical analysis and Heckman two-stage model. The conclusions are as follows: the family life cycle has a significant impact on the farmer's farmland transfer behavior. Furthermore, the influencing factors of rural family land transfer at different stages of life cycle are different. From the perspective of human capital,a good labor health condition is not conducive to the participation of families in the support period in the conversion of farmland. Non-agricultural employment rate has a significant positive impact on family participation in farmland transfer during the dependence period and the burden period. From the perspective of farmers' perception, restricting the use of farmland, understanding the inflow side, the promotion of the village committee and the government-led transfer have increased the possibility of farmers transferring farmland at different stages to varying degrees. For families with more non-agricultural employment opportunities during the dependence period and the burden period, the confirmation of farmland rights promotes the transfer of farmland and the work of migrant workers by strengthening the stability of land rights. Therefore, when implementing the farmland transfer policy in practice, accurate farmland transfer incentives should be adopted to differentiate households with different life cycles.
