Demarcation,Circulation and Integration:Three Functions of Interface in Public Adminis-tration
Despite the growing importance of interface there remains in public administration studies a lack of consensus regarding its definition origins characteristics and functions,leaving the definition of interface in a state of little consideration but much self-expression.This paper aims to clarify these aspects by comparing related concepts and proposing that the core attributes of an interface include such as the calibration of heterogeneity,distinctiveness from and reaction to original subjects,and sustained effects.Three primary functions of interface in public ad-ministration are identified:demarcation,circulation,and integration.In interactions between the public and the government,for example,the demarcation function is evident both offline and online.Even if the specific pattern of the public-government interface is under constant re-construction,the interface acts as a boundary stone and consistently serves the purpose of dis-tinguishing between the public in the front and bureaucrats in the back.Within the spatial field of the interface,various elements circulate in one or two directions among subjects.The circu-lation,especially in public administration,often has a purpose and is subject to various rules.Multiple subjects not only make mechanical contact or simple encounters at the interface,but also undertake some form of integration,through which different subjects communicate with each other,share resources,unify standards,enhance capabilities,and gradually move toward a cooperative state.Bringing the concept of interface into the studies of public administration,we can set up a unique analytical perspective for such issues as public-government interaction and inter-department collaboration.
