证人证言是证据形式的一种,在刑事诉讼中起着十分重要的作用。数据显示，我国刑事案件证人出庭率较低的现状由来已久，其产生的原因是多方面的。既有立法缺陷、司法执行存在弊端等客观方面原因，也有民众法律意识薄弱和出于自身安全考虑等主观方面的原因。证人不出庭作证破坏了刑事诉讼贯彻的直接言词审理原则，使立法者加大庭审中控辩对抗力度的立法旨意无法实现，使法官难以查明案件真实真相，影响了他们作出公正的裁决。我国为了解决证人出庭作证难的现状，通过《刑事诉讼法》及相关司法解释初步建立了强制证人出庭作证制度：规定了证人出庭作证的条件，强制证人出庭作证的措施和豁免权，证人的保护等方面的内容。但从有关证人出庭的各项具体规定来看，仍存在着许多悬而未决的问题。强制证人出庭作证制度要得到有效的实施，还需要克服一些来自司法体制、诉讼程序和证据制度方面的困难和挑战。本文结合国内外法律制度、观点，以及国内司法现状，从强制证人出庭作证的概念、特征和具体类型入手，深入分析证人出庭作证的现状与不足，并对2012 年刑事诉讼法中制度修订等方面进行研究，以求能对强制证人出庭作证制度提出些许建议，以推动制度的完善。本文共分为四个部分，具体结构如下：第一部分：本文通过调查研究，了解我国证人出庭的司法现状。近一步引出强制证人出庭作证的必要性，以此为基础研究强制证人出庭制度。第二部分：通过对《刑事诉讼法》的法条及相关司法解释的分析，整理出我国强制证人出庭作证制度的整体框架及各项制度的立法意义。第三部分：通过对资料的查阅，结合国外立法，指出我国强制证人出庭作证制度存在的不足。第四部分：提出完善我国强制证人出庭作证制度的建议，包括明确证人出庭的范围、完善证人拒证权制度、明晰拒绝出庭作证证人书面证言的效力，以及通过立法明确司法机关强制证人出庭的执行程序。
