中文摘要：

为了研究政府保障性住房的租金管理问题，引入住房过滤理论对保障性住房的租金设定分析讨论。以出租型保障性住房为研究对象，对保障对象进行分类并设计了包括过滤器、保障条件、租金限定的保障性住房租金模型。结果表明：在保障条件方面，低收入者和中低收入者根据收入线限定，而夹心层根据收入线和工作年限限定；在租金限定方面，低收入者可免收租金，中低收入者根据成本收益法收取租金，夹心层根据学历和工作年限分层收取租金。

英文摘要：

To invest igate the issue of rent management in government affordable housing,in this paper,we discuss affordable housing rent based on the filtration theory. In our study of affordable rental houses,we classified users and built an affordable housing rent model,which includes filtration, guarantees ,and rent limits. The results show that, with respect to guarantees, those with low and medium- low incomes were lim i ted by their incomes, while earners in the sandwich layer were limited by both their income level and their length of work. In terms of rent,the rent of low-income earners may be completely subsidized,whereas the rent of medium-low-income earners should be set according to cost-benefit principles. Lastly,the rent of earners in the sandwich layer should be based on their education level and length of work.
