车辆动力电池回收的演化博弈分析
Evolutionary Game Analysis of Vehicle Power Battery Recycling

倡导可持续发展背景下，电动汽车企业通过打造旧产品回收体系以履行产品延伸责任，并通过生态化设计产品和提高再生料的应用水平降低生产成本。以电动汽车企业有义务对其销售的车辆上的动力电池回收为前提，针对回收过程参与者间策略抉择问题构建综合车企、专业车企、非正规企业及用户四方演化博弈模型，分析四方达成理想稳定演化策略的条件，得出：综合车企与专业车企的合作机制需要合理控制双方成本，以保障双方产品延伸责任的同时履行；综合车企作为产业骨干，其有力的控制保证了回收体系的运转效果，车企合作中，综合车企保持适当控制强度有助于维持良好博弈状态；两方车企集中力量选择干预用户或非正规企业，可以实现对另一方的间接控制。
In the context of advocating sustainable development, electric vehicle companies fulfill product extension responsibility by building a recycling system for used products, and reduce production costs by ecological product design and high level of recycled material usage. Based on the premise that electric vehicle companies have the obligation to recycle the power batteries on their vehicles, a four-party evolutionary game model of comprehensive car companies, specialized car companies, informal enterprises and users is constructed for the strategic choices of participants in the recycling process, and the conditions for the four parties to achieve an ideal stable evolutionary strategy are analyzed. The cooperation mechanism between comprehensive car companies and specialized car companies needs should be cheap enough. And then the fulfillment of the extended responsibility of both parties’ products will be ensured; as the backbone of the industry, the comprehensive car companies have strong control to ensure the operation effect of the recycling system. In the cooperation between the car companies, the comprehensive car companies maintain appropriate control intensity to help maintain a good game state; The two car companies concentrate their efforts on intervening with users or informal enterprises, which can achieve indirect control over the other party.
