「為民服務」是警察機關最主要的業務項目，在這個以「顧客至上」的服務時代裡，如何善用資訊科技，建立不受時空限制的高效能電子化政府服務，是每個警政單位努力的目標。然而從各國警政機關的網站觀察，在便民及宣導服務功能方面，仍有許多值得討論與改善之處。本文透過內容分析法，以民情與我國近似及全般刑案犯罪率1低於我國的日本為比較觀察對象，進行分析二國首都區警政機關網站服務功能之架構，歸納二者網站對便民服務功能提供之差異，做為彼此強化各項便民措施參考。從中發現我國警政網站在網路報案方面為日本所無，然而在兒童治安認識與宣導、網路犯罪分布地圖，日本則有較多值得我國深入了解及借鏡之處，惟兩國對Web2.0 創新服務應用，目前則都有進步空間。

Initialing an online and good-performance internet service portal is crucial for all police departments to achieve "Serving the people", and is also very helpful during practicing "Customer first" in service process. Through the literature review about many countries’ police department internet services, the paper points out that most of them still need many improvements. With Japan's low crime rate and low criminal cases, Tokyo’ police internet service is a good case study to be compared with Taiwan. Using content analysis as research method, this paper compares two police departments’ websites services and characteristics. The paper finds out that Tokyo website doesn’t provide the online crime reporting system like Taipei, but more in-depth research about Tokyo security awareness, advocacy for caring children and the network map of crime distribution is fully worthy of learning. However, the internet Web2.0’ innovative services are needed for both countries.
