成本差异对双寡头企业行为的影响分析

Analysis of Cost Variances Impact on Duopoly Enterprises

文章构建了生产成本不对称双寡头研发生产模型,采用逆推归纳法求解模型的Nash均衡解,研究了生产成本差异系数与参与程度、研发水平、产量间的关系。研究结果表明,生产成本差异系数与研发水平间呈正向关系、与参与程度和总产量间呈负向关系。

This paper constructs a RD production model of duopoly enterprises whose production cost is unsymmetrical.By using converse inductive method,the model is solved,and Nash equilibrium of the model is obtained.Furthermore,it studied the relationship among the diversity factor of the production cost,degree of participation,the RD level and the output.We found that the relationship between diversity factor of the production cost and the RD level is positive,and the participation degree and the total output is negative.
