文摘Status quo of urban and rural public goods supply in China is analyzed.Firstly,public goods supply in rural areas is inadequate,for example,inadequate supply of agricultural infrastructure,lack of expenditure in agricultural science and technology,problems of rural drinking water safety,problems of rural roads and transportation,low levels of health care,weak rural public culture,short supply of farmers'education.Secondly,the system and level of urban public goods provision can't meet migrant workers'demand,for example,less migrant workers are employed by the governments'direction;migrant workers are isolated by urban housing project and these workers have difficulty in receiving city social security.One reason of new generation migrant workers facing the double marginalization of rural and urban crisis is that urban and rural public goods supply are different in particular the inadequate supply of public goods in rural areas.Three countermeasures are put forward in order to relieve new generation migrant workers'double marginalization of urban and rural,which include increasing financial input in rural areas in order to achieve equalization of urban and rural public goods,perfecting the preferential agricultural policy to increase rural public goods supply,making urban public goods supply as a guide to promote the new generation migrant workers into the city.
