The effects of government subsidies on decentralised reverse supply chains
研究了政府补贴对分散式逆向供应链中回收材料流的影响，通过四层网络均衡模型和实际案例发现，补贴处理器层级在均衡量、补贴有效性和弹性方面表现更优。
This paper examines the impacts of exogenous government subsidies on recycled material flows in decentralised reverse supply chains where players behave according to their own interests. We present a four-tiered network equilibrium model consisting of the sources of electronic scrap products and the collectors, processors and demand markets. We mathematically transform the players’ optimality conditions governing players’ behaviours into a variational inequality formulation. We investigate the impact of alternate schemes of government subsidies on the equilibrium amount, subsidy effectiveness and subsidy elasticity. The real-world case study shows that subsidising the tier of processors demonstrates the superiority of the investigated performance measures.
