To study the impact of decision sequences on supply chain pricing and revenue,a supply chain system consisting of a supplier and two retailers is constructed.In this model,two types of decision sequences regarding wholesale prices between the supplier and the retailer are considered,namely supplier-led and retailer-led.And there are four pricing decisions between retailers regarding retail prices,namely,simultaneous pricing,pre-emptive pricing,subsequent pricing,and joint pricing.The results show that vertical competition between the supplier and the retailer affects the optimal wholesale price and does not affect the optimal decision of the retailer.For the retailer,joint pricing strategy is the dominant strategy,which is also a choice in the interest of the supplier and the supply chain in a complementary product market,but in a competitive product market the supplier prefers the retailer to choose simultaneous pricing.The results of the numerical experiments show that the supplier's returns are higher than the retailer's returns in most cases,and the retailer's returns are higher only in a complementary product market and when the retailer is the leader.
