Abstract: A Bertrand three-oligarch dynamic model for producing heterogeneous products is established, in which firm1 and firm 2 form R&D alliance. The stability of the model is theoretically analyzed using the stability criterion and the stability region of the speed of R&D adjustment is obtained by numerical simulation. The influence of the change of the speed of R&D adjustment and technology spillover rate on R&D input is also discussed. The result shows that with the increase of the speed of R&D adjustment, the market will lose its stability. When the technology spillover rate of firm 3 is certain, the smaller technology spillover of the R&D alliance will not be conducive to the stability of the whole market. Finally, through the study of multistability, it is concluded that the state of attractors and the size or shape of the basin will change with the change of the speed of R&D adjustment.

Key words: three-oligarch, heterogeneous products, technology spillover, bifurcation, multistability
