在产品差异的情况下,消费者对各公司产品偏好不同从而公司定价优势也不同.以市场需求和定价优势为随机变量,建立了一个非对称双寡头期权博弈模型来研究异质公司的策略投资问题.推导出抢占投资阈值存在的条件,并根据其存在情况分析出子博弈纳什均衡策略.研究发现:需求下降诱发过度开发的现象除了因抢占市场所致外,还可能由公司定价优势更大程度的增加引起.此外,就相关参数对投资阈值的影响做了比较静态与敏感性分析,为公司的投资行为提供一定的理论依据和实践指导.
In the case of product differentiation, the consumers have different preferences for each company’s products and the company has different pricing advantages.Based on the market demand and pricing advantages as a stochastic variable, an asymmetric duopoly game model is built to study the strategic investment of heterogeneous companies Problem.The precondition of preemptive investment threshold is deduced and the subgame Nash equilibrium strategy is analyzed according to its existence.It is found that the phenomenon of overdevelopment caused by the decline of demand not only results from the preemption of the market but also the advantage of pricing by the company In addition, the author makes a comparative static and sensitivity analysis on the impact of relevant parameters on the investment threshold, and provides some theoretical basis and practical guidance for the company’s investment behavior.
