影子价格与企业管理决策

The Shadowprice and the Enterprise Management Decision

本文利用线性规划与非线性规划模型，讨沦了目标函数增量，影子价格及相应的常数项增量的特征区间之间的关系，从理论上对文［１］、［２］、［３］中的问题作出了解释。我们还给出了线性规划与非线性规划发生悖论的充要条件，对文［５］。

In this paper, we discuss the relation among objective function increment, shadowprice and corresponding constant term incremental characteristic interval, using the model of Mathmatical Programming. we gave the explanation to the guestions in the papers [1], [2], [3] theoretically. Furthermore, we discuss the sufficient and necessary conditions for existence of the more - for - less paradox in Mathmatical programming. In this paper,we also entend the results in the papers [5], [7].
