全球甚多民主國家，例如英、美、日、加拿大等刑事司法體系
中已存在著很多的民間化機構。其中英、美、加、愛爾蘭、盧森
堡、波蘭等國之私人警衛甚至超出警察的總人數。除此之外，一些
非營利性之民間組織、志願團體、義工等亦如私人警衛一般大量的
存在於民主社會，來協助警察或刑事司法機關，共同維護社會安
寧。
作者引述警政策略發展之各類新趨勢，以及民間化治安策略各
國實例，暨保全業與私人警衛之發展現狀，論述民間化治安體系之
發展確實在治安維護效率與效果方面，有其一定之時代需求與優
勢。最後，以新竹市警察局在此方面之革新實驗為例，說明我國警
政在此方面發展進程以及未來賡續研發之方向。

Privatization is a global trend in the criminal justice institution and its
managerial practices. Nowadays, the number of people working in the private
security has exceeded that in the public security, i.e. the police force, as
can be seen in U.K., Canada, Ireland, Luxemburg and Poland. In addition,
the Non-Governmental Organization (NGO), volunteer and neighborhood
watch of various private sectors are booming with the rapid development of
the private security. And these new social protection institutions have greatly
boosted the police and Criminal Justice agencies in their efforts to safeguard
society.
The authors describe the new development of this trend and cite various
nations’ privatization practices to explain this trend, showing that privatization
of social protection really works in terms of maintaining community
safety and stability. Further, this paper uses Hsinchu City Police Bureau as
an example of successful experimentation of this new strategy.
