Abstract: With the scarp tide of new energy vehicle power battery,China's power battery recycling industry has entered the key period of recycling policy system construction and channel construction.To analyze the impact of government policy on the recycling channels of scrap power,the ecological design level and recycling of power batteries was considered as a government fund policy of reward factors,and the choice of power battery closed-loop supply chain recycling channels in this policy was studied.Six power-based battery closed-loop supply chain recycling channel models with or without government fund policies were constructed,the impact of government fund policy on equilibrium decisions,economic and environmental performance was analyzed,the relationship between government fund policy and social welfare with government receipts was researched,and the best recovery channels from the perspective of different members was discussed.The results showed that the fund policy implemented by the government could improve the level of ecological design,environmental benefits and the profit of each member of the closed-loop supply chain.Manufacturer and retailer both favored the manufacturer's recycling channel.Third-party recycling company hoped to undertake recycling activities alone,and consumers who chose retailer or third-party recycling company to recycle would get a higher price difference.The government preferred manufacturer to recycle from the perspective of social welfare,but the recycling channel of manufacturer was not conducive to the perspective of fiscal balance.
