摘要：证人出庭作证制度是现代中内外国家不可或缺的重要司法制度。证人出庭作证是现代司法制度中的普遍原则和庭审制度的基本要求。同时也是《中华人民共和国刑事诉讼法》对庭审方式规定所要求的。证人出庭作证，有利于控、辩双方对证人证言的质证，查清犯罪事实，打击犯罪活动；有利于增强案件审理的透明度，减少或者防止错案的发生；有利于庭审方式的改革，推动社会主义法制建设等。然而，证人作证难问题却长期以来一直困扰着我国的立法和司法部门。我国刑事诉讼的举证质证过程，基本上就是公诉人长时间宣读大量证人证言，书面证言使用太多。刑事诉讼法第150条对“主要证据”的规定比较抽象，主要证据材料又没有一个明确的标准。上海市黄浦区法院统计表明，今年来该法院审理的刑事案件中证人出庭率只有5%。另有数据表明受贿罪、涉黑案件、有组织犯罪等几类案件的证人出庭率几乎为零。

　　本文试图通过对刑事诉讼中证人出庭作证的现状、原因、以及中外法律之间对该制度规定的差别、试针对现存的问题，为完善我国证人出庭作证制度，提出、形成个人的观点与看法。
