本文在不对称双头垄断期权博弈模型基础上讨论了利润流现值和沉没投资成本为梯形模糊数的情形并进行了扩展,对企业技术创新投资策略进行了分析。构建了模糊环境下追随者、领导者的投资价值和投资临界值的模糊表达式并进行数值分析。分析表明模糊环境下仍存在最优投资策略,随着梯形模糊数的沉没投资成本期望值的增加,企业的投资价值下降而投资临界值上升。为模糊环境下投资决策提供了一种解释。
Based on the asymmetric two-headed option game model, this paper discusses the case that the present value of the profit flow and the sunk investment cost are trapezoidal fuzzy numbers, and expands the investment strategy of technological innovation of enterprises. The fuzzy expression of follower, leader’s investment value and investment critical value in fuzzy environment is constructed and analyzed numerically. The analysis shows that there still exists the optimal investment strategy in the fuzzy environment. With the expected value of the sunk investment cost of trapezoidal fuzzy numbers increasing, the investment value of the enterprises declines while the investment threshold increases. It provides an explanation for the investment decision in the fuzzy environment.
