运用不对称双寡头期权博弈模型,在投资成本不对称的基础上引入建设时间不对称,采用逆向归纳法导出建设时间和投资成本同时不对称的双寡头企业投资期权博弈模型;对存在的抢先均衡、序贯均衡和同时投资均衡进行分析讨论,投资均衡分析表明,建设时间和投资成本都会对企业投资策略产生影响,对于每个企业而言能否成为领先者以及何时投资要视建设时间和投资成本的相对优劣势等具体情况确定,但努力建立建设时间和投资成本的相对优势会给企业带来更多投资先机;进一步分析建设时间和投资成本对投资策略的影响显示,与建设时间相比,投资成本对企业的投资临界值影响更大,因此企业应花费更多精力通过降低投资成本获得竞争优势。
By using asymmetric duopoly game model, asymmetric construction time is introduced on the basis of asymmetric investment cost. Adverse induction is used to derive game model of duopoly business investment with asymmetric investment time and investment cost. The preemptive equilibrium , Sequential equilibrium and simultaneous investment equilibrium analysis and investment equilibrium analysis shows that the construction time and investment costs will have an impact on business investment strategy for each business can become the leader and when to invest depending on the construction time and The relative advantages and disadvantages of investment costs and other specific circumstances to determine, but efforts to establish the relative advantages of construction time and investment costs will give businesses more investment opportunities; further analysis of the construction time and investment costs on the investment strategy shows that the construction time In contrast, the cost of investment has a greater impact on the firm’s investment threshold, so businesses should spend more energy gaining a competitive advantage by reducing their investment costs.
