城郊居住分层理论的拓展:基于市场摩擦的角度

为了研究异质性收入居民的空间分层,在一个单中心模型中融入公共服务根据有无住房实施差异性分配,以及房子有最小面积这种市场摩擦,发现存在住房需求收入弹性为零的刚性需求者,得到完全分层和混合分层两种模式.数值模拟表明,完全分层模式下,城区公共服务优势能够减少郊区的穷人数量,增加所有居民的福利;混合分层模式下,城区公共服务能够增加郊区的穷人数量,并使得城区刚性需求者的福利受损.郊区土地供给增加,在完全分层模式下会吸引低收入者流向郊区,但在混合分层下,会减少郊区的低收入者.
Expansion of the theory of residential stratification:Based on the market friction
To re-explores residential stratification of people with heterogeneous income,in the monocentric model,we account for the market friction that public services are enjoyed by people according their house ownership and there is minimum area of the house.It is found that there are people with zero income elasticity of housing demand,and completed stratification and mixed stratification.In the completed stratification,the more urban public services,the less number of poor people in the suburbs and the more welfare of all people.In the mixed stratification,the more urban public services,the more number of poor people in the suburbs and the less welfare of urban rigid demanders.The increase of land supply in the suburbs would attract low-income people to the suburbs in the completed stratification,but would reduce the suburban low-income people in the mixed stratification.
