Abstract: The development of new energy vehicles in China is rapid, but the technological innovation ability is still need to be improved. In order to promote its long-term sustainable development of them, the Dual-Credit policy came into being. Sixteen A-share listed companies of new energy vehicles were selected as research samples, and the DID model was applied to study the impact of Dual-Credit policy on technological innovation. The results show that the "double points" policy can effectively improve the innovation performance of enterprises. At the same time, enterprises can promote their own technological innovation development by adjusting the proportion of talents and actively expanding research investment. Therefore, in the future, new energy enterprises can increase investment in R&D, and add more talents to promote the breakthrough and development on core technologies of new energy vehicles.
