Recycling Model Selection for Electronic Products Considering Platform Power and Blockchain Empowerment

This paper considers a dynamic platform-based, closed-loop supply chain consisting of manufacturer and an online platform. As distributor the manufacturer, platform expands market scale by exerting power. At same time, to solve problem inconsistency between actual recycling amount theoretical in process waste electronic products, whole-process supervision products is carried out with help blockchain technology, which difficult tamper traceable. With differential game theory, four models without are established. The state feedback strategies derived from Bellman’s continuous programming theory. Through analytical results comparative analysis, adoption conditions impact on selection obtained. illustrated that introduction technology effectively improves real rate electronics, building trust consumers, benefits corporations certain conditions. However, it amplifies double marginal effect CLSC. Nevertheless, implementation still beneficial as adverse compensated improvement consumer surplus. In addition, study shows incentivizes members, who benefit model when fixed cost share ratio residual value electronics thresholds. That is, both better off enabled blockchain. Moreover, this model, social welfare increased, enable CLSC achieve related economy, environment, society.
