摘　　要：当我们构造多部门数量经济模型的时候,往往要将千千万万种产品归结为几种产品或者几个部门.讨论如何将多种产品归结或综合成1种或少数几种产品.指出如何确定综合产品的数量与价格.并且给出相应的计算公式.指出综合产品的数量、综合产品的价格与不变价、现价、真实物价指数、通货膨胀率之间的关系.The construction of multi-sector econometric model often involves grouping millions of different goods into a few products or sectors. This paper discusses the ways to aggregate or group multiple goods into a composite product or a few types of products. It also shows how the quantity and price of composite product are determined and provides the corresponding equations. In addition, the relationships between the quantity of composite product, the price of composite product, constant price index, current price index, true price index and inflation are presented.
