Preventing the return to poverty is the basis and prerequisite for consolidating and expanding poverty alleviation efforts and effectively linking them with rural vitalization，and the effective improvement of digital governance capacity of preventing the return to poverty is of great practical significance for high-quality promotion of rural revitalization strategy. From the perspective of application of New IT， there are four major problems in preventing return to poverty，namely, insufficient integration of multivariate data, poor application of intelligent monitoring and early warning； imperfect research on coordinated and precise policy implementation, and insufficient support for dynamic monitoring and control. The growth of digital countryside can promote the overall level of informatization，digital participation degree and network application scenarios，and comprehensively improve the ability of the integrated application of the new generation of information technology to help prevent poverty or the return to poverty. As the integration of the new generation of information technology continues to evolve and upgrade，driven by the digital countryside construction, the integration and application of big data，block chain，artificial intelligence，digital twin can provide a new means to solve the above problems and further improve the anti-poverty digital governance capacity. The improvement of anti-poverty digital governance capacity is not only one of the key tasks of digital rural development，but also the transformation and upgrading of rural social governance capacity supported by the achievements of digital rural development as a whole. By further strengthening the integration of New IT，it can construct a “digital twin”world of the population vulnerable to returning to poverty that is highly simulated and synchronized with the real situation of rural society. Through the two-way interaction of virtual and real space as the core evolution mode，the system adjustment and upgrading mechanism with three mapping as the main line can be formed in the whole process of poverty prevention. The mechanism of the intelligent anti-poverty digital governance will have the key capabilities of being driven by big data and intelligent models，enabling real-time prediction，decentralizing decision-making and precisely controlling the helping process. The digitalization and intelligence level of China’s national defense poverty alleviation can be effectively improved. At the same time，this paper proposes to improve the digital governance ability of preventing returning to poverty through five paths： change of thinking，planning and guidance，multi-level linkage，credible process and overall coordination.
