合理限定過失犯的歸責范圍是規范保護目的理論產生的原因,歸責的規范化與實質化是該理論產生的基礎。規范保護目的理論將歸責判斷從模糊的生活經驗標準轉到規范標準上來,對現代刑法歸責體系的建構發揮了決定作用,對不法構成要件的成立也有重要限制功能。在這方面,社會相當性理論具有不徹底性,容許危險理論的運作也需要規范保護目的理論的協助。規范保護目的理論有助于說明過失不法,借助該理論,客觀歸責理論"重構"了過失犯。確定規范的保護范圍,一方面應以規范保護目的為起點,另一方面應與單純的反射性保護效果劃清界限。就規范保護范圍的義務基礎而言,目前存在形式義務說、實質義務說和規范限制說的爭論。對我國來說,在罪刑法定原則框架下建構規范限制型的規范保護目的理論具有妥當性。在該理論的適用范圍上,既要反對以偏概全的"虛無論",也要反對不切實際的"萬能論"。

The protective purpose of rules theory aims to limit the scope of attribution of negligent crime.The basis of this theory is to normalize the attribution of consequences.With its help,the judgment of attribution moved from the fuzzy life experience to normalized standards,thus playing a decisive role in the construction of modern criminal law attribution system as well as helping to restrict the establishment of illegal elements.In this aspect,the operation of permissible risk theory requires the assistance of the protective purpose of rules theory,which has an advantage over the incomplete theory of social equivalence.Moreover,the protective purpose of rules theory helps to explain the illegality of negligent crime.Specifically,this theory assists objective attribution theory to reconstruct the negligent crime.To determine the protective scope of rules,on the one hand,we should use the protective scope of rules as a starting point,on the other hand,we should differentiate it from a simple reflective effect.On the other hand,several theories debate on the obligation basis of the protective scope of rules including the formal obligation theory,the substantive obligation theory,and the normative limitation theory.For our country,in the framework of the principle of legality,it is appropriate to construct the protective purpose of rules theory with the model of the normative limitation theory.In the scope of application of the protective purpose of rules theory,it is necessary to oppose the overgeneralized "nihilism"and unrealistic"omnipotence"
