Using the von thunen model the author analyzes the mechanism for the rise in urban commercial house price and draw the following conclusions : when the urban commercial house price difference between central area and peripheral area is equal to or more than the cost to reside in peripheral area , rational buyers tend to buy commercial houses in peripheral area ; with the reduction of the cost to reside in peripheral area , the urban commercial house price level in central area tends to be close to that in peripheral area ; given that the cost to reside in peripheral area is fixed , the urban commercial house price level in peripheral area is restricted by the price level in central area 摘要借鉴冯?杜能模型分析城市商品房价格上涨机理，可得出以下结论：当购买城市周边区商品房相比购买中心区商品房少支付的房价大于等于居住周边区所需多支付的居住成本时，理性购买者会作出购买周边区商品房的决策；随着周边区相比居住周边区居住成本的降低，周边商品房价格水平会趋近于中心区商品房价格水平；当周边区居住成本相对稳定时，周边区商品房价格水平受制于中心区商品房价格水平。

Therefore , the study on the land intensive utilization of the resource - typed cities is necessary no matter in the views of the protection of land resource , the perfection of land science , the development of the city or the sound collocation of the urban land . the land intensive utilization is brought forward by germany economist j . h . thunen , the sutra theory of land rational intensity , then continued by british economist , a . marshall , the law of land diminishing return , and developed by the current studies on the urban land intensive use , it has been classified into four types : capital intensive - typed , labor intensive - typed , technology intensive - typed and ecology intensive - typed 根据综合指标,得出葫芦岛市土地利用为中度粗放利用,其城市用地结构、利用空间和利用强度配置不合理,土地利用经济效益较差,城市可持续发展有待于进一步提高,城市土地集约利用潜力很大;而盘锦市和阜新市城市土地利用为一般集约利用,其城市用地结构、利用空间和利用强度配置较不合理,土地利用产出一般,城市可持续发展受到一定破坏,城市土地社会问题显著,土地集约利用潜力较大。
