Abstract: As an item of living necessity,the residential house falls into the category of inflexible commodity within certain range of price.When the suppliers of residential houses realize this,they tend to reduce the amount of supplies through coordination and thus raise the price with the purpose of gaining more profits.Then the curve that indicates the supply will become negatively skewed.Under such circumstances,because of the imbalanced demand and supply,the price of the houses may rise continuously.To check this trend,the government should make policies to interfere with the price in light of a balanced demand and supply of residential houses.

Key words: the husing price, living necessity, market mechanism

摘要： 住房作为我国居民的生活必需品,在一定价格区间内属于非弹性商品;当商品住房供给者认识到这个特点时,就会"互相勾结",减少供给量,提高价格以获取更多的收入,此时,供给曲线就成了负斜率的;在这种市场特性下,由市场需求和供给的共同作用,房价一旦背离均衡价格,就会出现持续上涨。为有效抑制房价的持续上涨,需要政府介入,针对商品住房市场供给和需求的特征,采取相应的对策。
