Abstract: To discuss the effect of discarded electronics fund policy on operation decision and operation efficiency of closed-loop supply chain,based on the influence of government environmental tax,recycling subsidy and award-penalty for product design on the cost of new products and remanufactured products,the Stackelberg game theory was used to investigate the influences of fund policy on optimal product design decision,production decision and profit in the closed-loop supply chain.With the help of numerical analysis,the best regulatory level of environmental tax,recycling subsidy and award-penalty for product design were explored.The results showed that the manufacturer's choice of disassemblability design strategy was related to the cost parameter of product design and the level of award-penalty,but had no direct relations to the environmental tax and recycling subsidy.The environmental tax and recycling subsidy were always detrimental to the manufacturer but conducive to the remanufacturer,and the damage to the manufacturer's economy could be made up by the implementation of award-penalty policy for product design.The government should make the appropriate environmental tax,recycling subsidy and award-penalty for product design to promote synchronous development of new product and remanufactured product,and maximize the total social welfare.
