The influence of returning stolen goods on sentencing is mainly manifested in the following aspects: first, returning stolen goods and paying back compensation to reduce the property losses caused by crimes and reduce social harm; Second, returning stolen goods and compensation can reflect the penitent attitude of criminals; Third, returning stolen goods and compensation can save the victim's material losses; Fourth, not all types of crimes can reduce or make up for the social harm and losses; Fifth, we should pay attention to combining the return of stolen goods with other sentencing circumstances for comprehensive consideration.
