2. Because fake and shoddy products themselves mean fraud, the case of signing a contract to buy qualified products, but the other party actually delivered fake and shoddy products involves two charges of contract fraud and selling fake and shoddy goods. The mainstream view is that this belongs to the imaginative concurrence in criminal law theory, and it is convicted by a key judgment mentioned in 1. However, there are also views that concrete analysis is needed to find out the subjective intention of the suspect and make a targeted conviction. For those who have real business conditions and facts, they are convicted of selling fake and shoddy goods only on the grounds that they adulterate the business process and obtain excess profits. For employees who are not in the industry at all, who obviously fabricate false facts or false qualifications and identities and commit fraud under the cover of selling goods, they are convicted of contract fraud. Convicting according to this view is difficult to operate and grasp in practice.
