实证结果表明，从长期看日本第三产业就业比重上升与实际汇率升值正相关，而中国的相应变量间不存在类似长期关系。比较分析得出结论：只有在汇率适度浮动，资源在部门间流动壁垒减少这两个条件满足时，汇率升值才会产生资源配置作用，推动劳动向非贸易部门转移，逐步优化就业结构。

Two kinds of models by estimating pool equations and panel estimation have been constructed. Based on the idea of Reduced Form Model, by adopting lags-adjustment or not, time-series dynamics models of the fluctuation of urban residential real estate market, in which the endogenetic and the exogenous sensitive variable include, have been estimated. In logarithmic form the models are applied in a case.
