摘要：The dual-credit policy imposes stricter product supply requirements on automakers, while subsidy policies are gradually shifting focus to infrastructure operators. This study examines how the synergy between these industrial policies influences the adoption of new energy vehicles (NEVs). Using a system dynamics model, we investigate the interactions and dependencies among stakeholders in the NEV ecosystem. By considering varying levels of collaboration between industry, universities, and research (IUR), we analyze the incentive-state-response mechanism to evaluate how the two policies affect NEV market penetration and technological innovation. Key findings include: (1) Enhanced IUR collaboration drives technological advancements among manufacturers, and when combined with the dual-credit policy, this collaboration accelerates commercialization of technological innovations. (2) While both the dual-credit policy and infrastructure subsidies positively impact the market diffusion of NEVs, their impacts differ. The dual-credit policy serves as a catalyst for rapid technological progress among manufacturers, whereas infrastructure subsidies exhibit a delayed effect on market adoption. (3) Optimal policy synergy is achieved under high-intensity IUR collaboration, maximizing market penetration and technological progress. These insights underscore the importance of coordinated policy frameworks in fostering sustainable NEV adoption and innovation.
