EPR约束下退役动力电池回收的闭环协同机制及政策调适研究

我国新能源汽车动力电池回收体系中存在的关键协同断点，正在严重阻梗产业的闭环良性发展。为此，考虑EPR（生产者责任延伸）制度约束下动力电池回收体系的多重反馈回路及动态高阶次复杂关系，从产业链层面、产业与政策交互层面和政策设计层面，自底向上探究促进我国退役动力电池回收利用的闭环协同机制，给出EPR制度创新及调适建议。具体包括：（1）构建覆盖“政府-电池生产商-整车厂-回收利用商-消费者”等利益相关者的决策模型，从产业链层面探究多责任主体间的闭环契约协同机制。（2）考虑多重非线性反馈回路和政策时滞性，构建因果回路图和存量流量模型，从产业与政策交互层面，探究EPR制度与动力电池产业耦合的闭环协同机制。（3）基于内容、工具和主体协同等维度，从政策设计层面评估我国动力电池回收领域现有政策的协同缺失，并给出调适建议。成果可为我国动力电池产业链责任主体的协同决策提供方法，为政府创新EPR制度提供理论依据。

The key cooperation breakpoints in China's new energy vehicle battery recycling system are seriously hindering the healthy development of the industry. Therefore, considering the multiple feedback loops and dynamic higher-order nonlinear complex relations of electric vehicle battery recycling industry under EPR (Extended Producer Responsibility) regulation, the study has a bottom-up exploration of the closed-loop collaborative mechanism to promote recycling and utilization of waste electric vehicle battery in China from the industrial chain level, industrial and policy interaction level, and policy design level, and gives adjusted or innovative suggestions on EPR System. Specifically include: (1) The study constructs decision-making model of several stakeholders including "government-producer-recycler-consumer", and explores the closed-loop contract coordination mechanism among multi-responsibility entities from the industrial chain level. (2) Considering multiple nonlinear feedback loops and policy lag, the study constructs causality loop diagram and dynamic stock-flow model, then explores the closed-loop coordination mechanism coupling the EPR system with the electric vehicle battery industry from industrial and policy interaction level. (3) Based on content, tools and subject collaboration dimensions, the study evaluates current policy’s collaboration in the field of China’s electric vehicle battery management and gives adjusted suggestions from policy design level. The research results can provide methods for collaborative decision-making in China's recycling industry chain and theoretical basis for policy innovation on EPR regulation.
