New public management and e-governance for administrative reformation permeate worldwide, and the concernment on securing effectiveness inpublic areas, promoting productivity, and increasing custom satisfaction increase. Inhabitants, primary customers, demand a variety of convenient services to the government, due to the development of IT technology, and their attitude and recognition of participating in public areas increase. Thesechanges help citizens demand information and public services through internet that they want, and the changesalso help the government converge public opinions and become important measures for citizens to participate in deciding governmental policies. So, this thesis makes an overture of a possibility for utilizing PCRM, a way for citizens to participate in police administrations, by utilizing IT technologies in which everybody can participate without difficulty. The utilization ways are, on a large scale, classified with a macroscopic aspect and microscopic aspect. One of the macroscopic aspects is, first, the consideration of access to services and convenience in utilization. Though service systems are well constructed, utilization can not display its function, if access is restricted, access objects are restricted, and utilization is inconvenient. Second, services should have a both-sidedproperty. Ultimately, citizens\'participation should have a positive mutual participation level. One of the microscopic aspects is, first,that the police organizations have to establish a strategy to analyze and fractionate customers. Second, the police organizations have to make an effort to develop policy services and P.R strategies. Third, police organizations have to make an effort to manage customers. Fourth, police organizations have to execute customer management in general. Respective police agencies establish citizen participation plazas. But, citizens may suffer from confusion, because the included details are differentfrom each other. So, all of the police organizations have to maintain unity, to some extent, about citizen participation plazas. In addition, at the same time, consciousness aspects have to be accompanied for the reasonable utilization of PCRM. Citizens have to cultivate citizen consciousness, ownership consciousness for society, and positive participation consciousness to solve social problems. The government, operator, has not to offer one-sided information or has not to participate in utilizing PCRM passively, but has to reform recognition continuously and make an effort to interchange positively.
