Dynamic equilibrium mechanism of the closed-loop electric vehicle industry chain based on super-network model
构建了包含制造商、销售商、消费者和回收商的闭环电动汽车产业链超网络模型，用变分不等式分析各主体行为策略并求解动态均衡，通过数值分析找出主要影响因素，为政策制定提供建议。
At present, electric vehicle (EV) development has been widely accepted as a coping strategy by countries encountering environmental issues. However, there remain some uncertainties surrounding the future of China’s EV industry. The super-network provides an effective solution to the research on optimising subject decisions in a multilevel network model. On this basis, a closed-loop super-network model of the EV industrial chain system is proposed, which involves four different participants: EV manufacturer, sales company, consumer market, and recycling company. Furthermore, the variables are extracted based on practice, the behavioural strategies of each participant are analysed, and the dynamic equilibrium is determined with variational inequalities. Through numerical analyses, a further study is conducted on the main influencing factors and the extent of their impact on the dynamic equilibrium of the system. According to the results, the main research questions are answered, and some suggestions are made on the formulation of appropriate regulations.
