本文在产品市场需求与经营成本二重随机性以及二者具有相关性的条件下,建立了一个对称双头垄断期权博弈分析框架,研究了企业最优战略投资决策问题。在导出企业投资价值函数和最优投资临界值的基础上,着重分析了企业最优投资策略均衡规则及各均衡存在的条件,并就各参数对企业最优投资临界值的影响进行比较静态分析,得出了一些有意义的结论,同时给出了经济解释。
This paper provides a framework of symmetric duopoly option game and discusses the optimal strategy decision problems in corporate investment under the stochastic conditions of both project demand and operation cost which are correlative. We analyze especially the equilibrium rules of optimal strategy and its conditions and make a comparative static analysis to the influence of parameters to optimal thresholds after educing investment value function and optimal investment threshold. At last, we draw some significant conclusions and make economic explanations.
