In order to win the war of poverty reduction，China should try its best to improve the quality of poverty reduction，realize stability of poverty reduction，and implement a guarantee mechanism for keeping lifting people out of poverty after the end of the war. This report asserts that，high-quality poverty reduction just means stable poverty reduction，and improving the quality of poverty reduction means continuously increasing the proportion of real poverty reduction and enhancing sustainability of it. China attaches great importance to improving the quality of poverty reduction，and has taken a series of measures，including adhering to poverty standard，conducting dynamic adjustment，monitoring and evaluating，improving the human capital and endogenous power of the poor，coordinating development measures with security measures，implementing specific measures of consolidating outcomes of poverty reduction and preventing falling back into poverty. So the current situation of poverty reduction is good，and the rate of poverty has dropped substantially year by year. However，in the last year of war of poverty reduction，restrictive factors on stable poverty reduction still exist，some of which are confusion in standard application，insufficient “development” of certain measures and lacking endogenous power. It is believed that absolute poverty should not be expected to disappear immediately and absolutely after 2020，thus a guarantee mechanism for sustainable poverty reduction is necessary. It is suggested that，in the first three years or so of the 14th Five-Year Plan，the current rural poverty alleviation system and the poverty registration system should be preserved，the important poverty alleviation measures should be embedded into the Rural Revitalization Action，and a more inclusive and integrated comprehensive social protection system should be explored. Meanwhile，it is suggested that a incidence of poverty below 1% could be taken as the sign of winning the war of poverty reduction.
