综合汇率指数方法研究

汇率属于价格的范畴,某货币与各种货币汇率的动态综合,就是综合汇率指数。综合汇率指数既然是一种价格指数,其编制的方法与一般的价格指数编制原理是一致的。在我国,综合汇率指数方法的研究,可以在一些金融学、价格学的文献中看到。我们把所见到的综合汇率指数的计算式列举如下:1]综合汇率指数=计算期一国对各国的平均汇率/基期一国对各国的平均汇率(1)式中,平均汇率的计算方法是:平均汇率=Σ(本国货币对各国货币汇率×本国对各贸易量)/Σ本国对各国贸易量综合汇率指数=Σ(本国对各国货币的单一汇率指数×本国对各国贸易量)/Σ本国对各国贸…

Study on the Composite Exchange Rate Index

Composite exchange rate index can be obtained through the ratio of average exchange rates of tow periods, or weighted average of single exchange rate index. These two methods will reach unanimity while the former exclude the influence of trading structure movement to get the fixed composite exchange rate index, and the latter weighted by “mixed currency” of reporting period calculated with the exchange rate of base period. Being regarded as a kind of price, the compilation of exchange rate index is similar to common price index. It is featured by the weights of “mixed currency” of trading volume according to the requirements of itself as a relative. And the average index is merely a variety of composite exchange rate index rather than an independent form.
