经济变量不可能被长期低估或者高估。具体地说,名义变量可能被长期低估或者高估,而实际变量却不大可能出现这种情况,因为后者总是要趋于呈现其本来的面目。并且,实际变量要比名义变量重要得多。我认为人民币实际汇率不可能被长期低 Economic variables can not be underestimated or overestimated over the long term. In particular, nominal variables may be underestimated or overestimated in the long run, whereas actual variables are less likely to occur because the latter tend to tend to assume their true appearance. And, the actual variables are much more important than the nominal ones. I think the real exchange rate of RMB can not be long-term low
