Three strategies:non-cooperation(N),price-discount(D)and cost-sharing(S)strategies,are es-tablished to analyze the impact of"dual credit"policy on the production strategies of the gasoline vehicle manufacturer(GV)and the new energy vehicle manufacturer(EV).The results show that when the credit price is lower(higher),the increase in market size,decrease in cost efficiency factor and battery price will induce GV to increase(decrease)the production of G-vehicles and fuel economy level.The profit of GV is always the highest under the S strategy.The profit of EV is higher under the N strategy when credit price is lower,while profit of EV is higher under the D strategy when credit price is higher.The S strategy should set a lower price discount than D strategy to attract EV to participate in collaborative R&D.The above findings suggest that larger market sizes,lower battery prices and lower cost efficiency factors will weaken the actual effect of the"dual credit"policy when the credit price is lower,which also provides some important management insights for automotive manufacturers.
