This chapter tries to solve the following issues:as theconscious awareness of law-makers,the penalty-crimerelationship determines how to make law;as the form ofideas,the penalty-crime relationship regulates and guidesthe process of law-making and judicature;penalty andcrime as provided by law is nothing but the model for thepenalty-crime relationship presupposed and defined bylawmakers;the presupposition and definition of thepenalty-crime relationship is the value-based evaluativeactivity on the grounds of cognition;the change invalue-based criteria and the inherent contradiction of theobjective to beevaluated is the fundamental precondition for the definitionof the penalty-crime relationship;the change in classcontradiction is the basic cause for the change inevaluative criteria;the change in the objective to theevaluated reflects the demands and interests of the rulingclass to a certain extent,and lastly;as the evaluativeform of negating crime,penalty and its effectiveness dependheavily on the unity of compulsiveness and justice.

文章论述了刑罪关系作为立法者的自觉意识决定着刑事立法；刑罪关系作为观念的形式，规束并引导着立法和司法，法律中规定的犯罪与刑罚，是立法者设定的刑罪关系范式；刑罪关系的设定是以认识为基础的价值评价活动，价值标准的变动性和评价对象的内在矛盾性，是刑罪关系设立的根本前提，指出了阶级矛盾的变化是导致评价标准不确定的根本原因；评价对象的转移，在一定程度上反映出统治阶级利益的需要。刑罚作为对犯罪否定评价的方式，其有效性在于强制性与正义性的统一。

In chapters 1-3, some typical models of western school change in the 20〓century are commented on. The author analyses emphatically the characteristics oftheories for change and strategies in Dewey's Chicago experimental school,Montessori's Children's Home and Neil's Summer Hill School in the upper halfcentury. The methodology on change in that period are summarized as changing theschools in the way of innovation, enriching the strategies for change with theexperimental methodological thoughts, surpassing the antithesis between twoextremes with the thinking principle of continuity.
