Figure 1
A diagram of the supply chain competition under subsidy policies. The diagram shows two main supply chains: the green supply chain and the conventional supply chain. The green supply chain consists of a green manufacturer and a green retailer, while the conventional supply chain consists of a conventional manufacturer and a conventional retailer. Arrows indicate the flow of goods from manufacturers to retailers and then to consumers. The government is shown to influence these supply chains through different subsidy policies: the no-subsidy policy, the price-subsidy policy, and the green-subsidy policy. These policies are directed towards consumers and affect their purchasing decisions.Competitive structure of green and conventional supply chains under green promotional subsidy policies
