Abstract: Product recycling is an important part of green manufacturing system. The recycling of waste household appliances occupies a large component of it. In the recycling of waste household appliances, the recycling mode that e-commerce platform connects professional recyclers with recycling users has become a new development direction. Inevitably, there are complex conflicts of interest between the two groups, which hinder the development of the recycling industry. Based on this, the complex interest distribution and investment decisions of recyclers and e-commerce platforms in collaborative recycling business are studied. An evolutionary game model is constructed to analyze the evolutionary stability equilibrium state and evolutionary stability path when both groups “increase investment”. Combined with numerical analysis, the influence of various influencing factors on the evolutionary results of the model is studied. The study show that: the e-commerce platform and recycler both choose the ideal state of “increasing investment” as the premise of ESS evolutionary stability strategy, and there is a sub-optimal situation. The function between investment cost and additional recovery amount is a key factor, when this factor presents a certain functional relationship, there i no suboptimal situation. The platform sets reasonable commission rates for recyclers to facilitate cooperation. It is better to improve the investment utilization rate of cooperation between both parties in exchange for more recycling quantity than to increase the recycling price to attract more consumers to participate in recycling.
