Abstract:Team is one of the two greatest hot issues in management in 90's.Agents reward system is critical to incentives in teams,which is one of the most important problems in incentive mechanism designing theory,and the relative performance evaluation in a group is the base of incentive mechanism designing theory.The authors optimally design the system for share of profit among agents,and also develop a relative performance evaluation system for agents in a group,and have some conclusion to guide the practice.
