Abstract: How to deal with the relationship between foreign aid and endogenous development, economic development and social environment balance is a key problem for the country’s rural revitalization. The mechanism of how social entrepreneurship promotes rural revitalization show that: Rural revitalization is the process of creating, developing, and realizing social entrepreneurial opportunities. It is also a process in which social entrepreneurs help villagers discover rural values, co-creating values and sharing values through empowerment. The discovery of rural value mainly comes from the psychological empowerment to villagers; The creation of rural values is based on the ability empowerment to villagers and structural empowerment to village; The balance and sharing of values is achieved through the structural empowerment of social entrepreneurs based on the triple bottom line mechanism. Rural social entrepreneurship can be divided into four modes: project-based, exogenous-embedded, endogenous-initiative, and hybrid, and their effectiveness is also differentiated. Different villages can choose the appropriate social entrepreneurship model based on their own characteristics.
