自首作为刑法的一项量刑制度,对鼓励犯罪人积极投案、促进司法机关尽早侦破案件具有重要的作用。自首制度源远流长,虽然其欲体现的价值有相似之处,但是形式早已不尽相同。笔者试图比较古代自首制度(以较为典型的唐代自首为例)与现代自首制度之差异,以期对理解自首制度有所裨益。 As a sentencing system of criminal law, surrender voluntarily has an important role in encouraging criminals to surrender aggressively and promoting the judiciary to detect cases as soon as possible. The system of surrender has a long history. Although its values ​​are similar, the forms have long been different. The author attempts to compare the differences between the ancient system of surrendering (with a typical case of surrendering the Tang Dynasty as an example) and the modern system of surrendering, in the hope of helping to understand the system of surrendering.
