We can see that community correction can recollocate the limited judicial resource which is in favor of saving the cost of execution from a series of data, on the other hand, it is propitious to rebuild the light criminals. See from the penal base, the goal of the criminalistics in the 20th transfered to the criminal from the crime, the idea of correction was advanced on the base of going deep into the personality causation, because of which parole, probation and other community correction appeared and developed. See from the policy base, the popular international penal policy "polarization policy" also take a moment to community correction. It must divert some burden to the community if the country want to focus the strength into beating these terrorist, the fearful criminals. See from the environmental base, the developed country apply the community correction above 50%, which offers abundant experience and upstanding international surroundings to us, it also provide a largo flat roof for intercourse.

从一系列的数据可以看出，社区矫正既有利于行刑成本的节约，促进有限的司法资源的优化配置，也有利于对轻刑犯的改造，是符合行刑经济化的原则的；从刑事基础而言，近代刑事学派关注的目标发生了从犯罪行为到犯罪人的转变，在深入探究了犯罪的深层个性原因之后，提出了矫正刑的思想，并促进了假释、缓刑、保安处分等一系列现代刑法制度的出现与发展，这些都为社区制度的发展奠定了坚实的基础；从政策基础而言，目前国际比较流行的两极化刑事政策也为社区矫正的发展提供了契机，要集中有限的司法力量去打击那些恐怖犯罪、严重侵犯公民人身权利等犯罪，就必须将对轻刑犯的改造等部分负担转移到社区方面来；从环境基础而言，西方法治发达国家适用社区矫正的比例基本达到了50%以上，这为我国实行社区矫正提供了良好的国际环境和丰富的经验，并为我国和西方的法治对话提供了更宽广的对话平台。
