从住房过滤思想的提出到住房过滤机制的正式模型化,经历了一个长期的发展过程。过滤模型不仅描述了住房市场的动态特征,而且可以分析税收、补贴、租金控制等政策变量以及人口变动、贫富分化等社会结构变量对住房市场过滤机制的影响。对住房过滤模型发展过程和基本结论的理解有助于分析我国当前住房政策对房产市场的影响和住房保障政策设计的理论基础。 From the idea of ​​housing filtration to the formal model of housing filtration mechanism, has undergone a long-term development process. The filter model not only describes the dynamic characteristics of the housing market, but also analyzes policy variables such as taxes, subsidies and rent controls as well as the impact of social structural variables such as demographic changes and the polarization between rich and poor on the housing market filtration mechanism. The understanding of the housing filtration model development process and basic conclusions helps to analyze the current housing policy on the housing market in China and the theoretical basis of housing security policy design.
