基于"剩余收入法"的北京市居民住房可支付能力分析

长期以来,居民的住房可支付能力一直是我国住房政策所关注的主要问题.但是,住房可支付能力的测度一直是理论和实证的难点,特别是家庭收入差异以及住房质量差距的加剧又增加了住房可支付能力测定的难度.应用新的"剩余收入法"通过一个家庭购买一个"基准住房"总价格,并根据信贷政策测算了基本住房所需的融资成本,再测算基本的非住房消费,得到最低预算收入,并和真实收入比较来评估北京市居民的住房可支付能力.还比较了已购房改公房家庭和首次购房家庭的住房可支付能力.北京不同收入群体住房可支付能力存在明显的差异.中低收入家庭存在购买能力不足,拥有房改公房能提高家庭的住房可支付能力,经济适用房和限价商品房对提高中低收入家庭住房可支付能力的作用很小.提出发展共有产权经济适用房来满足中低收入人群的需要.
