国际贸易量是指按一定时期的不变价格为标准来计算的各个时期的国际贸易值,即用进出口商品价格指数除当期的进出口总值所得出的数值。各个时期的国际贸易量同某一时期作基期的国际贸易量相比较,就得出反映国际贸易实际规模变动的贸易量指数或物量指数。例如,根据联合国统计,工业发达国家出口值,1970年为2800亿美元,1978年为11736亿美元。出口价格指数,1970年为100,1978年为265,那么,1978年的国
The volume of international trade refers to the value of international trade in each period calculated according to the constant price for a certain period of time, which is the value obtained by dividing the import and export commodity price index by the total import and export value of the current period. The amount of international trade in each period compared with the amount of international trade in a given period as the base period leads to a trade volume index or quantity index reflecting the actual scale of international trade. For example, according to the statistics of the United Nations, the export value of industrialized countries was 280 billion U.S. dollars in 1970 and 1.7736 billion U.S. dollars in 1978. The export price index was 100 in 1970 and 265 in 1978. Then, in 1978,
