近年来，未成年人犯罪频发，已成为公众普遍关注的社会热点之一。检察机关作为国家法律监督机关和唯一参与未成年人司法保护全过程的政法机关，不仅仅要履行审查逮捕、公诉、犯罪预防、诉讼监督、法律监督的职能，按照法律规定办理未成年人刑事案件，更要贯彻“挽救 教育 感化”的方针，帮助涉罪未成年人走好未来的路。探究未成年人犯罪的原因很复杂，涵盖自身、家庭、社会等多方面，不是单纯的司法途径就能决，需要规范化、专业化、配套体系化建设。 司法社会工作者通过运用社会工作专业方法服务涉罪未成年人，起着涉罪未成年人与检察机关、社会之间的“桥梁”作用，承担着监督、沟通、教育和调查等职责，弥补了司法工作中的“硬”特性，进一步推动涉罪未成年人认识错误、改正错误，找准并解决根源性困境，保障未成年人的合法权益，达到矫正行为降低犯罪的目的，同时让未成年人刑事检察工作更有温度。从当前我国司法实践来看，社会工作者作为主体参与的社会调查制度是未成年人刑事检察工作必不可少的一部分，对检察机关提供量刑建议和审判机关量刑起着十分重要的参考作用。 本研究在梳理文献的基础上，通过跟踪社会工作介入检察机关未检案件社会调查制度具体实务，探究社会工作介入未检案件社会调查环节存在的问题和不足，在如何提升社会调查质量、提高司法社工专业能力、完善司法机关工作机制等方面提出可操作性的意见建议，进一步发挥社会调查报告对检察机关提供量刑建议和审判机关量刑的参考作用，促成检察机关和社工机构双方实现对对方角色的合理期待，并为实现司法社会工作与检察机关未成年人综合司法保护更加有效衔接方面提供理论与实践参考。

In recent years, the frequent occurrence of juvenile delinquency has become one of the social hot spots of public concern. As the national legal supervision organ and the only political and legal organ involved in the whole process of judicial protection of minors, the procuratorial organ not only performs the functions of reviewing arrest, public prosecution, crime prevention, litigation supervision, and legal supervision, but also handles juvenile criminal cases in accordance with the law. It is also necessary to implement the policy of "saving education and probation", and help the minors involved in crimes take a good future. Exploring the reasons for juvenile delinquency is very complex, covering many aspects such as self, family, and society. It cannot be resolved through judicial means alone, but requires standardized, professional, and supporting systemic construction. Judicial social workers serve the minors involved in crimes by using professional social work methods, play the role of "bridge" between the minors involved in crimes and the procuratorial organs and society, and undertake supervision, communication, responsibilities such as education and investigation make up for the "hard" nature of judicial work, further promote the minors involved in crimes to recognize and correct mistakes, identify and solve the root causes of dilemmas, protect the legitimate rights and interests of minors, and reduce correctional behaviors. The purpose of crime, and at the same time make the work of juvenile criminal prosecution more warm. Judging from the current judicial practice in my country, the social investigation system in which social workers participate as the main body is an indispensable part of juvenile criminal procuratorial work, and plays a very important reference role for procuratorial organs to provide sentencing suggestions and judicial organs to send sentences. On the basis of sorting out the literature, this study explores the problems and deficiencies of social work intervention in the social investigation of juvenile criminal procuratorial cases by tracking the specific practice of social work intervention in the social investigation system of juvenile criminal procuratorial cases by procuratorial organs.It puts forward practical opinions and suggestions on how to improve the quality of social investigations and the professional ability of judicial social workers, and further play the role of the social investigation reports to provide sentencing suggestions to the procuratorial organs and reference for the sentencing of the judicial organs, so that both the procuratorial organ and the social work organization can realize their reasonable expectations for the role of the other party. It also provides theoretical and practical references for realizing a more effective connection between judicial social work and the comprehensive judicial protection of minors in procuratorial organs.
