基于2011年、2013年和2015年的"中国社会状况综合调查"数据，研究农民工在流入地住房困难的代际差异，其结果表明：老一代农民工比新生代农民工更易发生住房困难；婚姻状况、单位性质、就业身份、居住地区类型对两代农民工住房困难的影响有显著差异；上一年度家庭总收入显著负影响两代农民工的住房困难；无论是新生代农民工还是老一代农民工，租住集体宿舍的农民工比租住廉租房、私人出租房的农民工更易发生住房困难；代际差异既直接影响也间接影响农民工的住房困难。为缓解两代农民工的住房困难，应当提高他们的收入水平，增加与他们的可支付能力相适应的租赁住房供给，适时为具有一定支付能力的已婚新生代农民工供应共有产权保障房，鼓励和支持用人单位改造宿舍或建造高品质的蓝领公寓。

Based on the data of "Chinese Social Survey", this paper studies the intergenerational difference of migrant workers' housing difficulties and their influencing factors. The results show that the intergenerational difference is obvious. Through the analysis of the function mechanism of the intergenerational difference, it turns out that the intergenerational variables not only have a direct impact but also have an indirect influence on their housing difficulties. The factors of marital status, employment status, unit nature and area types have significantly different influence on two generations of the migrant workers' housing difficulties. Household income in the previous year not only has a significant negative influence on the housing difficulties of the old generation of migrant workers, but also has a significant negative influence on the housing difficulties of the new generation of migrant workers. Whether the new generation of migrant workers or the old generation of migrant workers, the probability of housing difficulties of migrant workers who rent low-rent houses and private rental houses is lower than that of migrant workers who rent dormitories. Therefore, the government shall take specific measures to ease the housing difficulties of different generations of migrant workers. To reduce the probability of their housing difficulties, we shall improve their income, increase the supply of rental housing appropriate to their affordability, supply common-property affordable housing for the married new generation, encourage and support employers to renovate dormitories or build high quality blue-collar workers apartments.
