摘要/Abstract

摘要： 现有的理论中，生产帕累托最优条件不充分，其最优状态不是唯一的，使得理论自身及随后的应用上产生了一些矛盾。确定唯一最优状态的充分条件应该是：双方都满意的交换利益分割和边际技术替代率相等。前者保证交换实现，后者保证交换产生的利益被完全穷尽。只要遵循新交换原则，交换必能实现，但不一定是帕累托最优。信息不充分时，如果信息不对称者对对方所判断的生产函数改变了其真实生产函数的技术性质，交换虽能实现，但生产并没有达到帕累托最优。

Abstract: In the existing theory, the state of the productive Pareto optimal condition is not unique because the Pareto optimal condition is insufficient, which brings about some contradictions in the theory and the application. The sufficient condition of the only optimal state is that division of the exchange benefit is satisfied with two parties and MRTS should be equal. The former guarantees the exchange be surely realized and the latter ensures the exchange benefit be used completely. So long as the new exchange principle will be followed, the exchange must be realized, but it isn’t quite sure that the state is Pareto optimal. The reason is that when information is not sufficient and the technique nature of the productive function is changed, the productive can not be the Pareto optimal, even if the exchange is realized.

Key words: Rational person, Exchange benefit, the Pareto optimal productive condition
