家庭住房消费的最优决策

Families′ Optimal Decision on Housing Consumption

在中国住房市场快速发展的同时,房价逐渐攀升引起的一系列问题逐渐凸显,近年来政府持续出台政策进行多方位的调控。从属性上讲,住房是兼具消费品和投资品双重属性的特殊商品,通过将住房的这一特点纳入到以效用最大化为决策目标的家庭住房消费函数中,得出的均衡住房消费数量与家庭的财富总水平、未来价格水平正相关,与住房的购置价格负相关,并与住房信贷政策密切相关。因此,以住房双重属性为前提,才能进一步提高住房调控政策的效果,住房金融政策作为最重要的住房政策部分,应该从住房消费行为的微观层面完善相应的作用机制。

With the rapid development of housing market in China,a series of problems caused by increasing house price arise,and the government has published policies to control the problems from several aspects.Housing,in nature,is a special product with the double attributes of consumption product and investment product.By taking the attribute into the housing consumption function of families with utility maximization as the decision-making purpose,the author finds out that the equilibrium amount of housing consumption is positively correlated to the overall wealth of the families and the future house price.It is negatively correlated to the purchasing price and closely related with housing credit policy.Therefore,only by taking the double attributes of housing into consideration,can we improve the effect of housing adjustment policy.As the most important part of housing policy,housing financial policy should perfect its function mechanism from the microscope of housing consumption behaviors.
