Abstract: The migration issue is a key issue in water conservancy and hydropower projects, which is related to social stability and rural revitalization. In this paper, the factors influencing the willingness of reservoir migrants to transfer in farmland and the willingness of farmers in resettlement areas to transfer out of farmland and their coupling coordination relationship are studied by using geographic detectors, factor analysis method and coupling coordination degree model. The results show that（1） community integration status in resettlement sites, distance to farmland, skills training in farming and other skills, farmland value, number of agricultural laborers in households, and non-agricultural employment opportunities play a major role in influencing migrants’ willingness to transfer in farmland; non-agricultural employment level, degree of concern about damage to land rights and interests, availability of idle land, non-agricultural employment opportunities, knowledge of land transfer policies, and expection for income from land transfer play a major influence on the willingness of farmers in the resettlement area to transfer their farmland.（2） There is a two-by-two interaction relationship between the influencing factors, in which the explanatory power of the factors is significantly enhanced after any two factors interact. The interaction between the distance to farmland and the integration situation in the resettlement area has the greatest influence on the migrants’ willingness to transfer to farmland; the interaction between the degree of fragmentation of farmland, whether there is idle land, and non-agricultural employment opportunities are related to the impact on land rights and interests, has the greatest influence on the willingness of residents in the resettlement area to transfer out of farmland, and the per capita family cultivated land area of the resettlement area residents’ willingness to transfer out of farmland has a stealthy role.（3） There is a strong correlation between the migrants’ willingness to transfer in farmland and the resettlement area residents’ willingness to transfer out of farmland, which are mutually reinforcing and are in the basic coordination stage of farmland transfer willingness exceeding.
