Abstract: 【Objective】 Facing the new development stage of China's poverty alleviation strategy transformation, how to achieve long-term effective assistance for poverty alleviation farmers and reduce income inequality has become one of the important issues to be solved urgently for the comprehensive realization of common prosperity. 【Method】 Based on the data of China Family Panel Studies （CFPS）, the risk of returning to poverty and income inequality of poverty-stricken households were measured by multidimensional poverty vulnerability and relative deprivation index, and the "prevent the return to poverty effect" and "distribution effect" of Maintaining the Sustainability of Poverty Alleviation Policies were empirically tested by FRD method. 【Result】 It is found that the policies of Maintaining the Sustainability of Poverty Alleviation significantly reduces the multidimensional vulnerability to poverty and the relative sense of deprivation of the farmers out of poverty, indicating that persisting in Maintaining the Sustainability of Poverty Alleviation policies is conducive to the formation of a win-win situation of curbing the risk of returning to poverty and improving income distribution in the post-poverty era. Further research shows that the policies of Maintaining the Sustainability of Poverty Alleviation can significantly improve the labor participation and business income of households that do not rely on the government's guarantee of subsistence, inspire their mental state of through-labor-to-change-life. However, it will make the families who rely on the government to guarantee poverty alleviation have certain welfare dependence, thus weakening the long-term stability of poverty alleviation policy effect. 【Conclusion】 The government should strengthen the top-level design of Maintaining the Sustainability of Poverty Alleviation policies and take multiple measures to enhance the endogenous development momentum of poverty alleviation farmers, so as to realize the connection between poverty alleviation and rural revitalization and common prosperity.
