犯罪构成作为刑法中入罪的重要范畴,其本质是一种模型,这里的模型是指自然法意义上的、完美的、抽象的、开放的模型.本文认为法定说,理论说只是反映了犯罪构成的一个侧面,只是一些学者自己关于犯罪构成构建的一种现实模型,最终经过不断的完善只是无限接近于自然法中关于犯罪构成本质意义上的模型. As an important category of criminal offense, criminal constitution is essentially a model, in which the model refers to a perfect, abstract and open model in the sense of natural law.This paper holds that statutory theory says that theory only reflects the crime One aspect of the composition is only a scholar’s own model of the construction of crime composition. Ultimately, through continuous improvement, it is only infinitely close to the model of natural law that constitutes the essence of crime.
