As a unique perspective，welfare pluralism emphasizes the transformation of welfare provision from state to multi-departments，such as the government，market and social factors，reflecting the concept of “small government，big society”，and providing a feasible scheme to achieve the 2020's goal of building a well-off society. But for the families of poverty caused by illness，the situation is different according to the field research in Puyang，Taiqian and Fanxian of Henan province. The poor families caused by illness account for 30.2% of the total sample of poor households. Because of age，physical condition and so forth，the costs of family care are increased. On the other hand，healthy labor of this kind of family can not depart from their families and make money. Therefore，one can't make bricks without straw. The market-oriented industrial policy of alleviated poverty has limited effects，so is the opportunity of getting welfare income for market. So，in this kind of places，people can only rely on the support of the government to provide basic live security. Meanwhile social factors are also important supplement.
