As more and more attention was paid on the problem of poverty，the rate of absolute poverty has been declining significantly. Adequate food and clothing is no longer a critical issue that troubles us，however，in many large cities there are some new phenomenon of poverty，including transformational poverty generated by the transformation of the social basic institutional system and revenues shrinking with expenses arising poverty generated by long-term economic growth exceeded income growth，which caused a growth rate of relative poverty and subjective poverty. With the future of urbanization and Urban-rural integration，rural poverty will continue to reduce，while poverty in large cities will become increasingly prominent，the focus of pro-poor policies should gradually shift from rural to urban areas，especially large cities. The study researches on new types of poverty in megacities，exploring multidimensional poverty indicators；measuring the poverty levels of some typical megacities；analyzing reasons and mechanisms of the poverty arising in megacities；and then combined with the problems of existing anti-poverty policies proposing some recommendations of anti-poverty policy for megacities.
