组建横向型企业集团抉择的博弈分析

建立了一个博弈模型,研究横向型企业集团的形成抉择. 在模型中,有三家企业,其中两家生产同质产品,另一家生产相关产品. 博弈分为两个时期,在第1 时期,生产同质产品的两企业采取战略:组建集团或不组建集团,在第2 时期,三家企业进行Cournot2Nash 竞争. 文章给出了没有集团形成时Cournot2Nash 均衡结果,并且研究了替代系数对最优产量的影响;给出了形成集团时Cournot2Nash 均衡结果;研究了形成横向型企业集团的抉择,并且给出了数字化分析

Game analysis on formation choices of horizontal industrial group

In this paper , a game model that studies the formation choices of horizontal industrial group is devel2oped. In the model , there are three firms ; two of them produce a homogeneous product , and the other produces aninterrelated product . There are two periods. In period one , the firms that produce a homogeneous product select astrategy : to form a group or not . In period two , three firms play Cournot2Nash competition. Cournot2Nash equilibri2um outcomes is reached when no group is formed and the effects of substitutability coefficient on optimal outputs isstudied.Different Cournot2Nash equilibriumoutcomes can be got when a group is formed. The paper also studied theformation choices of horizontal industrial group , and a numberical sample is given.
