模糊环境下寡头垄断企业战略投资期权博弈模型

Options Game Model of Firm's Investment Strategy in Oligopoly Under Fuzzy Environment

针对具有寡头垄断市场结构的投资开发项目,建立考虑项目建设时间的期权博弈模型,并用动态规划的逆向归纳法进行求解;在项目预期未来利润流、项目开发时间和沉没投资成本均为梯形模糊数的模型假设下,建立模糊环境下的寡头垄断期权博弈模型,将随机条件下的博弈均衡结果及其成立的条件推广到模糊金融市场。算例验证结果表明所建模型及均衡结果合理。

In view of the oligarchic monopoly market structure about investment and development projects, oligopoly option game model that considering project construction time is Established, and the dynamic programming are applied to solve the model. Second-ly, under the assumption of the project construction time, expected future profit flow and sunk cost are trapezoid fuzzy Numbers, and oligopoly option games model under fuzzy environment is established. The game equilibrium results under stochastic condition and the conditions of its establishment are extended to the fuzzy financial market. Finally, a numerical example is used to verify the rationality of the model and the result of equilibrium.
