Considering the dynamics of emission reduction and brand goodwill,we construct a three-level supply chain network in the electronic equipment industry consisting of suppliers,manufacturers and retailers,and introduce government subsidies to study the optimal equilibrium strategies of supply chain members and the government under different circumstances using differ-ential game theory.The theoretical and example results show that government subsidies can regulate the profit distribution of the supply chain,and the subsidy rate is affected by both the profit situation of the members and the position of the game;under cer-tain conditions,consumers'preference for online channels is beneficial to the improvement of the overall profit of the supply chain,but is not conducive to the retailers'related work.
