Abstract:The high-quality development of family farms needs compound agricultural management talents, and multiple career experiences help to improve farmers" thinking cognition, knowledge level and diversified ability, broaden the network of social resources and realize complementary resources. it is an important way to shape compound agricultural talents. Based on the branding theory, social capital theory and dynamic capability theory, this paper constructs the theoretical framework and research hypothesis of "multiple career experiences-dynamic capabilities-farm high-quality development". Based on the survey data of stratified random sampling of 292 family farms in 6 cities and 12 counties in Hunan Province, the least square structural equation model (PLS-SEM) is used. This paper empirically explores the influence mechanism of multiple career experiences on the high quality of family farms. The results show that: 1) the multiple career experience of farmers significantly promotes the high-quality development of family farms, which can not only play a direct role on cognitive imprint and social capital accumulation, but also shape their dynamic ability through ability imprint to play an intermediary effect. 2) Learning and innovation ability, resource integration ability and environmental adaptability play a significant intermediary role in the mediating effect of multiple career experiences on farm high-quality development. among them, the contribution effect of resource integration ability is the highest, followed by environmental adaptability and learning innovation ability. 3) Multi-group analysis shows that multiple career experiences are more helpful to promote the high-quality development of family farms with high financing constraints, low policy support, non-provincial demonstration, aquaculture and start-up development. Therefore, in order to promote the high-quality development of family farms, returning entrepreneurs with multiple career experiences can be encouraged and guided to set up and operate family farms, pay attention to cultivating and improving the dynamic capabilities of the farms, promote the high-quality development of family farms, break down financing constraints, and optimize policy support according to the characteristics of different life cycle stages and different types of management and demonstration.
