企业的多层次最优投资策略与其神经网络控制研究
Research on Multi-Level Optimal Investment Strategy and Its Neural Network Control

所谓的以经济建设为中心，重点是以企业为中心。总体讲，实力强大的企业，会更有能力考虑和使用多方面、多层次经营模式。但是企业的多元化经营策略也是有很大风险的。本文给出了更为实用的两要素多层投资决策模型，并论证了其最优解的存在性。探究了投资预算对企业价值的科学机理。研究结果为使用的有效性提供了直接的证据，该结果推广了T. Cover教授等人建立的两要素单层投资决策模型。
For the so-called economic construction as the center, the focus is on enterprises as the center. Generally speaking, the larger the enterprise scale, the stronger the strength, the more conditions to adopt diversified business strategy. But the diversification strategy of the enterprise is also a great risk. A two-factor multi-level investment decision-making model is given, and the theoretical correctness of the model is proved. This paper probes into the scientific mechanism of the investment budget to the enterprise value. The results of this study provide direct evidence for the effective-ness of the application. Our results improve the ones of the two-factor single-layer investment decision model established by professor T. Cover et al.
