近年来，我国强奸未成年人犯罪案件的数量持续增长，该类案件成为社会广泛讨论的话题。针对未成年人的强奸犯罪，不仅对未成年人及其家人造成了严重的身心伤害，而且也造成了社会秩序的混乱。熟人强奸未成年人犯罪是指犯罪人与未成年被害人相互认识，犯罪人违背未成年被害人的意志与未成年被害人发生性关系的行为。对于这类犯罪，以往研究得不够。基于当前熟人强奸未成年人犯罪的态势和相应理论研究的不足，本文认真归纳了这类犯罪的特点，总结了这类犯罪的原因，并提出了相应的犯罪预防对策，以便为准确认识和科学治理这类犯罪做出努力。

本文包括绪论和正文。在绪论中，论述了研究背景及意义、文献综述、研究思路及方法。正文主要包括三个部分。

第一部分是熟人强奸未成年人犯罪概述。首先，界定了熟人强奸未成年人犯罪的概念，并通过对240个熟人强奸未成年人案例样本的分析，总结这类犯罪的主要特点。通过分析案例样本发现，此类犯罪主体多为青壮年未婚男性，文化程度较低且多数无固定职业，犯罪人往往单独犯罪，多数犯罪人与未成年被害人较为熟悉；未成年被害人大多为在校学生且有早恋现象；从犯罪行为来看，多数犯罪发生在夏季夜间的室内私密性场所中，预谋型犯罪与突发型犯罪比例相当，犯罪方法以暴力胁迫为主；从犯罪后果来看，此类犯罪对未成年人的心理、生理和日常生活都造成了较大伤害。

第二部分是熟人强奸未成年人犯罪的成因分析。影响熟人强奸未成年人犯罪的因素包括社会因素、个人因素和情境因素。其中，社会因素表现为传统性文化的负面影响、网络监管不力、家庭功能缺位和学校管理制度与教育内容不健全。个人因素包括犯罪人因素和被害人因素。情境因素包括地点因素、时间因素和酒精因素。

第三部分是熟人强奸未成年人犯罪的预防建议。结合熟人强奸未成年人犯罪的特征和成因，提出“社会预防+个人预防+情境预防”的熟人强奸未成年人犯罪预防体系。其中，社会预防分别从促进家庭良好互动、健全学校性教育与法治教育、加强社会法治教育力度、加强网络监管等多个角度展开。个人预防则主要从犯罪人预防和被害人预防两个方面展开。情境预防则从加强特定场所监管、时间预防和禁止未成年人饮用酒精饮料方面展开。

In recent years, the number of acquaintance rape crimes against minors in China has continued to grow, and such cases have become a widely discussed topic in society. Acquaintance rape crimes against minors not only cause serious physical and psychological harm to minors and their families, but also cause chaos in the social order. The crime of rape of a minor by an acquaintance is an act in which the offender and the minor victim know each other and the perpetrator has sexual relations with the minor victim against the will of the minor victim. This type of crime has not been studied enough in the past. This paper seriously explores this type of crime and proposes corresponding crime prevention countermeasures based on the analysis of the characteristics and causes of this type of crime in order to make efforts for the accurate understanding and scientific management of this type of crime.

This paper includes an introduction and a body. The main text consists of three main parts.

The first part is general information about acquaintance rape cases against minors. First, the concept of acquaintance rape crimes against minors is defined, and the main characteristics of such crimes are summarized through the analysis of a sample of 240 acquaintance rape cases against minors. Through the analysis of the case samples, it was found that the subjects of such crimes are mostly unmarried males of young and strong age, with low education level and most of them have no fixed occupation; the perpetrators often commit the crimes alone, and most of them are familiar with the minor victims; the minor victims are mostly school students and have puppy love in early age; in terms of criminal behavior, most of the crimes occur in indoor private places at night in summer, the number of premeditated crimes and sudden crimes is almost equal. In terms of the consequences of the crime, these crimes cause great harm to the psychological, physical and daily life of minors.

The second part identifies the causes for the acquaintance rape crimes against minors. The factors affecting the acquaintance rape crimes against minors include social factors, personal factors and situational factors. Among them, social factors are manifested as the negative influence of traditional sexual culture, poor network supervision, lack of family function and unsound school management system and educational content. Personal factors include offender and victim factors. Situational factors include location, time and alcohol.

The third part is the prevention suggestions for the acquaintance rape crimes against minors. Combining the characteristics and causes of rape of minors by acquaintances, the prevention system of "social prevention + personal prevention + situational prevention" is proposed. Among them, social prevention is implemented in different aspects, including having a good family interaction, improving sexuality education and law education in schools, strengthening social education on rule of law, and enhancing network supervision. Individual prevention is mainly carried out from two perspectives: perpetrator prevention and victim prevention. Situational Prevention starts with strengthening site-specific supervision, time prevention, and prohibition of alcohol consumption by minors.
