摘要
企业在维持原有经营过程中,将资金投资到股票市场.以盈余用作投资资本,进行多阶段动态投资.盈余过程由布朗运动刻画,效用函数刻画企业对风险和收益的态度.在效用函数最大的前提下,得到了各投资时刻的最优投资组合.该研究为企业提供了一种切实有效的投资策略.
Enterprises in maintaining normal operation invest into the stock market. The surpluses are used as investment capital by multi-stage dynamic investment. The surplus process of the enterprise is depicted by a Brownian motion and the attitude towards risk is depicted by utility function. The optimal investment portfolio at each investment time is obtained un- der the premise that the given utility function is maximum. The research provides a practical and effective investment strate- gy for enterprises.
