本文首先明确了现金所包含的范围,并在此基础上阐述了确定并保持最佳现金持有量的意义。然后探讨了确定最佳现金持有量的四种最常用的模式,其中重点阐明成本分析模式中的成本涵义以及建立该模型的假设,存货模式的套用公式,和在现金需求量难以预知的情况下可采用的随机模式。 This paper begins with a clear definition of the scope of cash and, on that basis, elaborates on the importance of identifying and maintaining the optimal amount of cash holdings. Then the four most commonly used models for determining the best cash holdings are explored, highlighting the cost implications of the cost analysis model and the assumptions used to establish the model, the formula for applying the inventory model, and the case where cash requirements are unpredictable Can be used under the random mode.
