摘　　要：自由贸易使得双方达到均衡的收入和福利水平,因而也就达到了均衡的货币购买力。本文研究发现,两国货币之间的汇率取决于两国相对的劳动力供给、两国临界商品生产的相对劳动生产率、消费者的消费偏好、两国相对的货币供给数量以及两国相对的货币周转速度。同时,得出汇率仅取决于两国临界商品价格水平之比的结论,这与Cassel购买力平价理论存在差异。本文提出解决人民币升值压力问题的基本思路是使临界商品向着中国具有更小比较优势的商品移动。When two countries participate into a free trade, they both achieve an equilibrium income. Therefore, both countries reach the equilibrium purchasing power of money. According to the study, the exchange rate between two currencies depends on the relative supply of labor between the two countries, the relative la- bor productivity in producing critical goods, consumer preferences, the relative money supply, and the relative turnover rate between two currencies. Further- more, conclusion that the exchange rate between two currencies only depends on the ratio of price of the critical goods produced in two countries is obtained, which is different from Cassellian purchasing power parity. One basic solution to the prob- lem of pressure on the appreciation of RMB is to change the critical goods of China from the goods with more comparative advantage to the goods with a less compara- tive advantage.
