Logistics service outsourcing is a key part of professional logistics, and this review looks at how it works in the market. The researchers analyzed existing studies on logistics outsourcing, market operations, and coordination management. They focused on how companies work together when one provides logistics services to the other, especially when there is unequal information. They found that before signing a contract, companies use signal transmission and screening models to deal with information differences. After signing, they use multi-task incentive contracts to manage the relationship. The review suggests that more research is needed in this area.
