Based on comparative analysis of the similarities and differences of each Auxiliary Police System among countries and areas such as England, U. S. A. Mainland China, Hong-kong and Taiwan, this article try to explore the possibility of using the full-time paid Auxiliary Police manpower to replace regular police engaged in non-enforcement work to allow more regular police can engage in law enforcement, and to reduce the work load of the regular police. The results of the comparative analysis found that each Auxiliary Police System has positive features and functions, while there are some difficulties to be overcome.
