中文摘要：

通过对农民工家庭房价收入比的测算，揭示其城市住房购买力不足问题和存在的区域差异，探索提升其住房购买力的途径和政策建议。利用统计数据和实地调研数据的测算，揭示了我国部分省市农民工家庭房价收入比过高，城市住房负担过重的问题。通过对农民工家庭的收入构成成分的分析，发现农民工家庭的财产性收入占比过低，沉淀于宅基地和住房的财产基本未得到显化。结合浙江省德清市、湖南省浏阳市典型农村发展实践的调研数据，认为运用市场手段盘活宅基地及存量农房，能够显著提高农民工家庭的住房购买力。研究结论：农民工家庭房价收入比普遍过高且存在地域差异，过高的房价收入比与农民工家庭较低的财产性收入相关，显化农村宅基地和农房财产，利于实现城乡土地“同地、同权、同价”，也有助于实现农民的财产权。提高其城市住房购买力。
