In retail competition, coordination between suppliers and retailers to match the supply and demand is the key to increasing the overall supply chain profits. To ensure the achievement of the coordination objectives, a mechanism is needed that can guarantee profits for all members of the supply chain. This paper will provide an overview of the supply chain coordination mechanism when there is competition between retailers. This review will focus on two things, namely, supply chain coordination and competition between retailers that are influenced by promotional strategies and customer preferences. This study can provide information related to the existing supply chain coordination literature and retailer competition so that it can provide an overview of the limitations of research on supply chain coordination in retail competition.
