Abstract: Under the Socialist System of Laws with Chinese characteristics, criminal law and commercial law are two important departments. For the regulation of the wrongful acts in the field of commercial transactions, it needs the "co-operation" between criminal law and commercial law. The internal theoretical logic and the related system structure of the two should be attached great importance. At present, there are still many problems in this area, it is necessary to reconstruct the relationship between criminal law and commercial law based on the idea of "Dimensional criminal law":At the theoretical level, it should evaluate the unlawful acts from the perspective of the overall legal order and establish an adaptive mechanism of criminal responsibility; at the institutional level, it should reconstruct the criminal law system, establishing its adjustment mechanism, strengthening the effective connection with commercial law and the flexibility of judicial interpretation.
