摘要
本文通过研究超额需求函数与多项式的关系得：（１）对于（ｎ—１）个关于ｐ１，ｐ２…，ｐｎ－１的多项式Ｅ。（ｐ１，ｐ２，…，ｐｎ－１），ｓ＝１，２，…，ｎ—１，若满足条件：则Ｅｓ，ｓ＝１，２，…，ｎ—１均为一个经济的超额需求函数．（２）对无穷级数ｇ（ｐ），也存在含有两个消费者与无穷种商品的经济，使得其超额需求函数恰好为ｇ（ｐ）．
In this paper, the relation among aggregating individual utility,excess demand function and polynomial functions is investigated. the main results are: (l) given n - 1 polynomials satisfying some conditions,then each polynomial can represent an excess demand function for corresponding commodity. (2) In economieswith infinitely many commodities, given a series satisfying some condition, then it can be generated as a excessdemand function for a particular commodity.
