Based on the content of part 1 , the author of this paper respectively deals with it from three aspects : ( 1 ) the aim and choice of this field is to balance the profits between society and individual , not only to encourage inventer " s creation but also to make the level of social science advance ; ( 2 ) criminal law starts only when laws except for criminal law have lost function to wrong conducts on intellectual property rights ; ( 3 ) the legislator shall pay close attention to the question weather the departments of justice execute the criminal law on the crimes of intellectual property rights 该部分主要是沿着第一部分的逻辑推演，在认定刑法应该介入的前提下，在理论上追问刑法介入的深度和广度。分别做了三方面的探讨：一是价值目标限制，即个人利益与社会利益的衡平、鼓励创新与科技进步的衡平；二是法律性质限制，即后盾法的刑法应是最后制裁法；三是刑法介入的纵向程度限制，即适度观念下的注重实证效果。
