Abstract:The digital economy is a digital form of economic development,exhibiting characteristics such as platformization,chaining and non-regionalization. The integration and development of technologies such as artificial intelligence blockchain, and big data with economic development not only lead to the digital transformation of traditional crimes,but also form a huge network black and gray industry, which brings criminal security risks in finance,network and information,intellectual property,and other aspects,posing serious challenges to criminal law legislation and criminal justice. Criminal law theory needs to respond positively to this from both legislative and interpretive perspectives. From a legislative perspective, the active prevention of criminal law has its limits and should adopt a development model of “combining criminal law governance with diversified governance, synchronizing legal governance with technological governance, emphasizing both source governance and key governance,and integrating the clarity of the criminal law with the accusation of crime”. From the perspective of interpretive theory, the new forms of crime that have emerged in the digital economy era have raised new issues regarding traditional criminal law theories such as jurisdiction theory ,illegality theory,attribution theory, and accomplice theory. It is necessary to propose and construct a activism interpretive theory. This roughly includes four aspects:(1)The prerequisite for jurisdiction within the domain is to maximize the principle of facilitating the investigation and punishment of cybercrime, and a centralized and specialized jurisdiction model can be considered that is, the higher-level public security organs or people's courts can concentrate cybercrime cases and entrust them to specific public security organs or people?s courts for unified centralized jurisdiction.(2)With the development of the digital economy, the types of illegal behavior in cybercrime have been expanded, and the evaluation standards and focus of illegal results will shift. For the illegal evaluation of cybercrime and information crime,it is necessary to shift from “result without value” to “behavior without value”and this “ behavior without value” also needs to be further distinguished.(3) The joint accountability of individual responsibility and platform responsibility is different from other crimes in the attribution mode of online crime. Online platforms have important significance in crime prevention,and it is necessary to moderately strengthen the attribution of online platforms. For example,based on the principle of integrating platform,data ,and algorithms,it is necessary to reconstruct the purpose and system of liability based on standardized protection data flow and information security. From a legal perspective it is necessary to clarify the relationship between platform obligations and the crime of refusing to fulfill network security management obligations data flow and infringement of public personal information algorithm abuse and assistance in information network criminal activities,in order to solve the problem of liability determination for network crimes.(4)According to the theory of the constituent elements of chain type individual crimes,joint crimes should not be recognized based on the traditional theory of accomplice. The evaluation focus of network type joint crimes is on the illegal form of behavior,which requires changing the previous judgment standards of “conspiracy as the center responsibility as the center and contact as the core”,and developing the judgment methods and standards of “principal offender as the center,illegality as the center,and causality as the core” .
