摘要
影子价格在资源的配置中具有重要的指导意义,但是在应用时如果不考虑资源约束项的应用范围,得出的结果将不具备指导性。运用影子价格的边际定义对其与资源常数项的关系进行考察,通过理论与实例分析影子价格在资源配置时的有效范围,避免影子价格的误用。
Shadow price has important guiding significance for resource allocation.However,in the application we often forget the scope.In this paper,we analyze the relationship between the shadow price and the resources,through the theory and examples to judge the range of resources.All of this is in order to avoid the misuse of the shadow price.
