摘要

摘要在城市经济学中,通常假设租户在可及性和住房规模之间进行替代,当住房规模较小时,这种替代将变得没有弹性。它解释了穷人是如何在市中心生存的。然而,对这一假设进行的实证研究有限,因为正规住房通常规定最低住房规模。非正规住房中的生活区域不受监管,为研究人员提供了检验这一假设的机会。然而,这两个市场之间的差异使它们不具有可比性。本文通过研究香港的细分单元(SDU)(主要在住房单位中非正式细分)以及邻近公共交通对住房规模弹性的影响,对租金的规模弹性进行了实证测试。研究结果表明,小型住房租金的规模弹性较低。SDU的尺寸弹性(占整个公寓平均尺寸的四分之一)约为整个公寓的一半。我们进一步发现,当SDU租户住在离地铁站更近的地方时,他们必须为同样规模的增长支付更多的费用。与整户家庭相比,他们不太愿意为更大的占地面积支付更多的费用。

How do the poor survive in an unaffordable city? – An empirical study of informal housing households living in Hong Kong
ABSTRACT In urban economics, tenants are commonly assumed to substitute between accessibility and housing size and the substitution would become inelastic when the size is small. It explains how the poor survive in city centres. However, limited empirical study on this hypothesis is conducted because minimum housing size is commonly regulated in formal housing. Informal housing, in which the living area is not regulated, offers an opportunity for researchers to examine this hypothesis. Yet, differences between the two markets render them non-comparable. This paper contributes by conducting empirical tests on size elasticity on rent by studying Hong Kong’s sub-divided units (SDUs), which are mostly informally subdivided in housing flats, and the effect of proximity to public transportation on size elasticity of housing. The results suggest that size elasticity on smaller-sized housing rent is lower. Size elasticity of SDUs (with one-fourth of the average whole flat size) is about half of the whole flats. We further found that SDU tenants have to pay more for the same size increase when they live closer to the metro station. Compared with whole flat households, they are less willing to pay more for larger floor area.
