Poor forecasting of the results of improving administrative and criminal legislation in terms of criminalization / decriminalization of criminal acts, imperfection of the administrative-tort and criminal policy of the state leads to the assumption of unjustified criminalization of similar socially dangerous acts, the establishment of excessive administrative and criminal law prohibitions on the implementation of certain activities, as well as to incorrect decriminalization of previously established criminal law prohibitions. The study of the influence of socio-economic factors on the formation of the administrative-tort and criminal policy of the government, acting as interrelated parts of a single punitive-legal policy, is due to the need to identify the directions of its implementation, the result of which is a change in administrative and criminal legislation. The analysis of the current administrative and criminal legislation, the systematization of the theoretical provisions of the problems of criminalization / decriminalization of acts, comparison of the factors that act as their causes, made it possible to identify the grounds for the legislative changes, which include: the emergence of new types of socially dangerous human activities; unfavorable dynamics of certain types of human behavior dangerous to society, which were regulated in administrative legislation or were not considered at all as offenses; the need to strengthen the protection of constitutional rights and individual freedoms; mistakes of the earlier decriminalization of criminal acts.
