中文摘要：

笔者使用北京市2002年8月到2010年8月的月度数据，研究了地价与房价的非线性动态关系。研究结果表明：北京市房价的变动对于地价变动的影响是非线性的，其关系适合使用LSTR1模型来拟合，如果前1期的地价变动高于27．61％，前3期和前5期房价的变动对于当期地价的影响是非线性的正的影响。其政策含义是，在现阶段通过相关政策的实施。调节地价的过快增长（增长速度低于27．61％）是非常重要的，只有这样才能大大减缓房价对地价的推动作用。

英文摘要：

The authors used the monthly data of Beijing from 2002 to 2008 and researched the nonlinear dynamic relationship between land price and housing price. The findings show that the influence of housing price on land price is nonlinear and their relationship can he simulated with LSTR1 model. If the change in land price is higher than 27.61% in the former first period, the change in the hous- ing price in the former three and five periods has nonlinear positive effect on the land price of the periods. The implication of the research for policy-making is that it is of great significance to restrain the fast increase （ the increase rate should be lower than 27.61% ） in land price through implementing related policies. Only in this way can the promotion effect of housing price on land price be retarded.
