外来未成年犯罪人是指从外地流入本地，不具有本地城市户籍，犯罪时已满14周岁未满18周岁的人。外来未成年犯罪人是我国未成年犯罪人中不可忽视的群体。在我国未成年人犯罪案件中，外来未成年人犯罪案件占有很大比重。外来未成年犯罪人兼具“未成年犯罪人”和“外来犯罪人”的特点。作为“未成年犯罪人”，一方面，他们处于身心发展不平衡的阶段，身体发育迅速，心理发展缓慢，情绪不稳定，逆反心理强，辨别是非能力差，自我控制能力和心理承受能力都比较弱，容易激化矛盾；另一方面，他们犯罪史较短，犯罪恶习不深，易于接受教育、感化，可塑性较强，因此，对他们实行社区矫正是十分必要的。但是，作为“外来犯罪人”，与本地犯罪人相比，他们流动性较强，成长经历往往复杂，心理状况特殊，行为特征显著，家庭教育缺位，文化水平较低，法律意识淡薄，劳动技能欠缺，生活环境、交往环境混乱。因此，在对他们进行社区矫正时，开展监督管理、教育矫正和帮困扶助工作都面临极大的困难。目前，学界对外来人口犯罪、未成年人犯罪以及未成年人社区矫正的问题进行了一定的研究，但是对于外来未成年犯罪人社区矫正还没有进行较为系统、深入的研究。因此，分析外来未成年犯罪人社区矫正的问题及原因，提出完善建议，对于健全相关立法，完善配套机制，落实监管帮教措施，提高外来未成年犯罪人社区矫正的适用率和效果，帮助他们顺利回归社会等，都具有十分重要的意义。 本文的正文包括五章，具体内容如下： 第一章绪论，论述了选题背景和研究意义、文献综述。通过搜集国内文献，对我国外来未成年犯罪人社区矫正的研究现状进行了总结和分析。 第二章对我国外来未成年犯罪人社区矫正相关内容进行了概述。第一部分先是分别介绍和分析了“未成年犯罪人”和“外来犯罪人”这两个词语的含义，在此基础上，对“外来未成年犯罪人”的概念进行了界定和分析。第二部分从犯罪数量、犯罪主体、犯罪类型、犯罪形式四个角度概括了外来未成年人犯罪的特点。第三部分在深入分析了地方实践情况的基础上，概括出外来未成年犯罪人社区矫正存在审前调查流于形式、差别适用普遍存在、监管帮教难度大以及矫正效果不理想的问题。 第三章分析了我国外来未成年犯罪人社区矫正问题形成的原因。本章分为三个部分。第一部分从法律制度层面进行了分析，认为当前存在的问题与现有法律制度不健全、法律内容不完善有关。其中，在法律内容方面，着重探讨了现有法律规定中审前调查制度和管辖制度存在的问题。第二部分从配套机制层面进行了分析。一是讨论了缺乏审前非羁押支持机制与外来未成年犯罪人审前羁押率过高的关系，进而分析了审前羁押率高对外来未成年犯罪人社区矫正适用率低的影响。二是探讨了社会力量参与程度不足与外来未成年犯罪人社区矫正问题产生的关系。首先，分析了当前专职工作力量严重不足的现状，提出了社会力量参与外来未成年犯罪人社区矫正的必要性。其次，探讨了社会力量参与程度不足的现状以及对外来未成年犯罪人社区矫正的影响。第三部分从个人身心原因和家庭社会原因两个角度分析了这些因素对外来未成年社区服刑人员监管帮教工作的影响。在个人身心原因方面，分析了外来未成年社区服刑人员的生理特征、心理特征和行为特征给监管帮教工作带来难度的原因。在家庭社会原因方面，分析了家庭因素、观念因素、教育因素和环境因素为监管帮教工作带来困难的原因。 第四章提出了我国外来未成年犯罪人社区矫正的完善建议。首先，在法律制度层面论述，从法律体系、法律内容两个角度提出了健全法律制度的相关建议。其中，在法律内容方面，重点论述了对审前调查制度和管辖制度的完善建议。其次，在配套机制层面探讨，一方面提出构建以观护基地、合适成年人参与制度为代表的审前非羁押支持机制，以降低外来未成年犯罪人的审前羁押率；另一方面，提出促进社会力量的有效参与，以提高外来未成年犯罪人社区矫正的效果。最后，在监管帮教层面分析，针对外来未成年社区服刑人员的身心特征和家庭社会因素提出了六项具体措施。一是针对外来未成年社区服刑人员的身心特征，建议提供恰当的心理帮助并落实行为监督；二是针对家庭社会因素，提出开展强制性亲职教育、更新公众观念、开展有效的教育矫正以及改善交往、生活环境四项举措，以便更好地落实对外来未成年社区服刑人员的监管帮教措施，提高社区矫正的效果，帮助外来未成年社区服刑人员顺利复归社会。 第五章结论，对全文进行总结，指出本研究的不足，并呼吁社会对外来未成年犯罪人社区矫正给予必要的关注。

Migrant juvenile offenders are the ones who moved from other places and do not have local urban registration. When they commit the crimes，they have reached the age of fourteen but not the age of eighteen. Migrant juvenile offenders are a group of juvenile offenders that can not be ignored in China. Among the cases of juvenile offense，migrant juvenile criminal cases account for a large proportion. Migrant juvenile offenders have two characteristics which are “juvenile offenders” and “migrant offenders” . As juvenile offenders, they have two different characteristics. On the one hand, their physical and mental development are unbalanced. Their physical development is faster than psychological development and they are moody. They have a strong reverse psychology and are poor of cognitive ability，self-control，psychological endurance. They are very easy to intensify conflicts. On the other hand, they are easy to be educated and influenced because their criminal history is short and criminal habits are not serious. Therefore, community corrections are quite necessary for migrant juvenile offenders.However，as “migrant offenders”, due to their strong mobility and complex growth experience, migrant juvenile offenders have more special mental status, more obvious behavioral characteristics，less family education，lower level of education，less legal awareness，limited skills and more chaotic living environment and communication environment than local offenders. Thus it is difficult to implement supervision and administration，educational corrections, and assistance of migrant juvenile offenders in community correction.At present, there are some academic research on migrant population crime, juvenile offense and juvenile offenders community corrections, but still there is no systematic and in-depth research on community corrections of migrant juvenile offenders. It is significance to analyze the causes of the problems of migrant juvenile offenders community corrections and propose suggestions. It is conducive to improve relevant legislation and support mechanisms. It is also necessary to strengthen supervision，education and assistance, and increase the rate of application, enhance the effects of migrant juvenile offenders community corrections. Helping them successfully return to and integrate into the society is the ultimate goal. This thesis includes five chapters, as following： Chapter One introduces the background, significance and literature review of the thesis. The thesis summarizes and analyzes the research status of community corrections of migrant juvenile offenders in China through collecting domestic literatures. Chapter Two gives an overview of community corrections of migrant juvenile offenders in China. The first part introduces and analyzes the meaning of two words, “juvenile offenders” and “migrant offenders”. This part defines and analyzes the concept of migrant juvenile offenders based on the two words. The second part generalizes the characteristics of migrant juvenile offense from four aspects: the number of crimes, the subject of crimes, the types of crimes, and the forms of crimes. The last part makes an in-depth analysis of the local practices and then generalizes the problems about pre-disposition investigation system on migrant juvenile offenders, the different application of community corrections, the difficulty of supervision, education and assistance and the unsatisfactory effects of corrections. Chapter Three analyzes the reasons of the community corrections of migrant juvenile offenders in China. This chapter is divided into three parts. The first part analyzes the reasons from the legal system aspect and the author considers that the current problems are related to the imperfect legal system and legal contents. In terms of legal contents, it focuses on the problems existed in the pre-disposition investigation system and jurisdiction system in the current legal provisions. The second part analyzes the reasons from the supporting mechanism aspect. Firstly, it discusses the relationship between the lack of pre-trial non-custodial supporting mechanism and the excessive pre-trial detention rate of migrant juvenile offenders, and then analyzes the impact of high pre-trial detention rate on the low rate of application of community corrections of migrant juvenile offenders. Secondly, this part investigates the relationship between the insufficient participation of social forces and the problems about migrant juvenile offenders community corrections. It analyzes the current situation of serious shortage of full-time work forces and puts forward the necessity of social forces to participate in the community correction of migrant juvenile offenders. Besides，it discusses the current situation of insufficient participation of social forces and the impact of migrant juvenile offenders community corrections. The third part analyzes the influence of physical，mental，family，social factors on the supervision，education and assistance work of migrant juvenile offenders in community correction. In terms of personal physical and mental reasons, this thesis analyzes the physical characteristics, mental characteristics and behavioral characteristics of migrant juvenile offenders in community correction，and the reasons why these factors bring difficulties to supervision，education and assistance. From the family and social aspect, this thesis analyzes the reasons why family factors，concept factors, education factors and environment factors bring difficulties to community corrections. Chapter Four puts forward the suggestions for the community corrections of migrant juvenile offenders in China. First of all, from the aspect of legal system, the author puts forward relevant suggestions on the improvement of legal system and legal contents. Secondly, from the aspect of supporting mechanism, on the one hand, the author proposes to construct a pre-trial non-custodial supporting mechanism represented by the care and education bases and appropriate adult participation system to reduce the pre-trial detention rate of migrant juvenile offenders. On the other hand, this thesis proposes to promote the effective participation of social forces in order to improve the effect of migrant juvenile offenders community corrections. Finally, from the aspect of supervision, education and assistance, the author puts forward six specific measures for the physical and mental characteristics of migrant juvenile offenders in community correction. Firstly, according to the physical and mental characteristics of migrant juvenile offenders in community correction, it suggests to provide appropriate psychological help and implement behavior supervision. Secondly, according to family and social factors, this thesis puts forward four measures including compulsory parental education, updating the public concept, carrying out effective education and improving the communication and living environment. These measures can implement the supervision, education and assistance for migrant juvenile offenders in community correction，improve the effects of community corrections and help them successfully return to and integrate into the society. Chapter Five is the conclusion of the thesis and the author points out the shortcomings of this study, and appeals to give necessary attention to community corrections of migrant juvenile offenders.
