摘要
作者利用城市经济学理论模型分析长效性保障房供给规模对城市空间和社会福利的影响。长效性保障房的供给会提高低收入居民的效用,缩小社会的贫富差距,抑制商品住房价格,但是也会扩大城市边界并减少公共服务。过度的长效性保障房供给将导致财政困难,减少社会福利。因此,应把握好长效性保障房供给规模和商品住房供给规模的均衡问题,只有供给适当规模的长效性保障房,才能实现社会福利的最大化。
Using urban economic model,the author analyzes the effects of long-term affordable housing supply scale on urban spatial structure and social welfare.Long-term affordable housing supply will improve low-income households utilities,mitigate inequality,and inhibit commodity housing price,but it will expand city size and reduce public service.If the supply scale of long-term affordable housing is excessive,it will lead to financial difficulties and reduce social welfare.Therefore,the balance between long-term affordable housing supply scale and commercial housing supply scale should be hold well.Only when the supply scale of long-term affordable housing is appropriate,the social welfare will be maximized.
