刑事制裁制度之目的主要在於應報、威嚇、隔離與矯正，矯正之最終理想則在於使犯罪者能夠復歸於社會，自我更生。惟，我國在近年所採行之「寬嚴併進的刑事政策」之下，基於嚴格之刑事政策，在未來所引發的長期監禁與收容人擁擠問題，已是不可避免的趨勢；在寬容之刑事政策下，所採取的轉向或替代措施，特別是導入社區處遇方式以替代刑罰之運用，雖然短時間內可以有效緩和監所擁擠問題，但是否可有效達到防止再犯與促其再社會化之目的，頗值探究。而對於近年來，社區處遇方式在我國刑罰制度上運用之成效，亦值探討。

them return to the society. The achievement of the adopting of community
corrections in the penal system in force will be examined finally.
