Abstract: The street-level bureaucracy researches ignore the assistants (xie guan yuan) group who are in almost every government departments in China, which can be called quasi-street-level bureaucracy. The urban-management assistants' anomie behaviors such as seeking personal gain, impeding law enforcement robbing formal authority have made a very bad influence on city regulatory, team construction and the government image. In the past decade, the local governments and the street-level bureaucracy individuals have made great efforts and try in the governance of the quasi-street-level bureaucracy, however, due to the urban-management multifarious affairs, formal staff and grassroots governance resources are scarce, the governance of xie guan yuan falls into the dilemma of "throwing sth. at a rat, but being afraid to break the vase" because they are both necessary and difficult to manage. The local government should focus on cultivating normal power and introduce market incentive mechanism in the reward of "quasi street bureaucrats" (xie guan yuan) groups, and strengthen the joint liability between the front-line law enforcement and xie guan yuan.
