To explore the transformation path and realization premise of conventional vehicle enterprise, a dynamic evolutionary game theory model is constructed between conventional vehicle enterprises and platform enterprises to explore the policy selection and main influencing factors from the perspective of platform ecosystem.How to cooperate between conventional and platform enterprise is studied. Computational results show that the total revenue, the distribution ratio, the cooperation cost and the cost-bearing ratio have a significant impact on the policy selection to guarantee the cooperation success between conventional vehicle enterprises and platform enterprises. In this new-energy transformation procedure, distribution and cost sharing mechanisms should be established so that benefits and advantages of synergistic performance, networking effects and value co-creation could be achieved.
