英文摘要：

This paper, based on the theoretical basis which combines land-regulated economy with the ＂three-in-one＂ attribute of land, analyzes the mechanisms of land policy, which are applied to macroeconomic adjustment in the financial crisis, in three aspects, the physical allocation, the value allocation and the property rights allocation. It is concluded that the three-in-one attribute of land and land-regulated economy are useful for formulating more efficient macroeconomic policies.
