我国公共住房消费融资模式及绩效分析

通过构建不同收入家庭住房支付能力与住房公积金关系计量模型,实证检验我国公共住房融资模式绩效。实证结果表明,在总平均、低、中、高收入家庭,公积金缴存额对居民住房支付能力的影响弹性均为正值,公积金与住房支付能力同向变化。高收入家庭的公积金缴存额对居民住房支付能力的影响弹性是最高的,而低收入家庭的公积金缴存额对居民住房支付能力的影响弹性最低。这说明在我国公积金对高收入家庭福利的贡献大于中、低收入家庭,中、低收入家庭的福利得不到保障,而高收入家庭获得的好处更多。所以今后应扩大公积金制度的覆盖范围,对公积金制度实行收入层次分段制,不断完善公积金制度与公共住房协调配合的机制、设立健全公共住房基金。

Analysis of Public Housing Consumption Financial System and Performance Evaluation

This paper builds an econometric model including variables of family housing affordability of different income levels and housing accumulation fund policy,which makes an empirical analysis on public housing finance system in China.The result indicates that in every(overall average,low,medium or high)level of family income,the amount of fund deposit always has an positive impact on housing affordability.The two variables change in the same direction.The fund deposit of highincome families relatively have the highest influence elasticity,otherwise the low-income families have the lowest influence elasticity.It shows that in China high-incomers benefit more from the housing accumulation fund policy than low-incomers.This paper provides several policies,such as expanding the coverage of the policy,making detailed rules and regulations according to different income levels,improving the harmonization of public housing accumulation fund policy and public housing system,setting up a public housing fund.
