Based on researches aiming at volunteer teams in 5 museums，this paper studies on museum volunteers' essential feature，incentives，motivation and satisfaction in many ways. The study finds out that，on the whole，volunteers are in a high degree of satisfaction on the environment and the chance to learn and train in the museum；and they are positive towards improving abilities and public-spirited. Recently，most museums use “hard incentives” in voluntary work，which helps to create many professional，stable and efficient volunteer teams. However，it also has limitations. The incentive mechanism needs to be improved in creating a more unhindered communication access and a better platform for volunteers to express their emotions.
