Abstract: This paper discusses how to prevent durable goods from producing a large amount of waste in the short term like fast-moving consumer goods (FMCG) through extended producer responsibility (EPR). On the basis of existing research, from the perspective of planned obsolescence, this article builds a dynamic model of durable goods, based on continuous time using the optimal control method to explore the optimal result of centralized decision making and decentralized decision-making of market equilibrium. Meanwhile, this paper reveals the incentive effect of EPR constraints under different market structures for producers to extend the life of the product design. Finally, based on the analysis process of the theoretical model, the conclusions of the research are verified by numerical simulation and case study. The results show that under the perfect competition market structure, the implementation of a single Pigouvian tax or only deposit return system can realize the optimal output and also provide enough incentive for producers to extend the service life of the product design; In an imperfect competitive market structure, at least two EPR constraints, tax and subsidy, are needed to achieve the optimal outcome of output and design life.
