In recent years, juvenile delinquency has become a social phenomenon that cannot be ignored. Takingthe social control theory as the analysis perspective and applying the research method of criminal economics,this study analyses the influence of the ratio of per capita disposable income of urban and rural families, the grossenrolment rate of high school, the detection rate of public security organs, the exemption rate of the court, and theproportion of the juvenile population to the total population on juvenile delinquency by setting up a cointegrationmodel using the juvenile delinquency data from the period of 1997 to 2021. The results show that the grossenrolment rate in high school, the detection rate of public security organs and the juvenile crime rate changepositively, the court exemption rate and the juvenile crime rate change negatively, and the proportion of juvenilepopulation in the total population does not have a significant effect on the juvenile crime rate. According to theconclusion of the model analysis, in order to reduce the juvenile crime rate, it can be achieved by optimising thesocial distribution system, improving the education level of juveniles, and insisting on the leniency and severity ofjuvenile justice.
