Abstract: Consolidating and expanding the results of poverty alleviation, enhancing the endogenous motivation of poverty-stricken areas and the masses, and promoting the common prosperity of farmers and rural areas are essential requirements for comprehensively building a modern socialist country. From targeted poverty alleviation to common prosperity, achieving sustainable poverty escape development is the fundamental path. This article constructs a conceptual framework for sustainable poverty escape from three aspects: poverty alleviation resilience, poverty alleviation levels, and endogenous sustainable development after poverty alleviation, explains its meaning and influencing factors, explores sustainable poverty alleviation paths and mechanisms, and thus consolidates poverty alleviation during the transition period. The results provide ideas and strategies for promoting the integration of people who have been lifted out of poverty into rural revitalization and urban and rural economic cycles. It also provides research inspiration for the sustainable development of underdeveloped areas after the transition period, the continuous increase in income of low-income people and accelerating the modernization of agriculture and rural areas.
