The illegal building is an important cause of social contradictions, is the  focus and difficulty of the government work, the new characteristics of  the illegal building at the present stage: easy to build, hidden, difficult to  dismantle, so there is urgency and necessity to improve the efficiency of  law enforcement. The social harm of illegal building is relatively invisible, so the government's attention to the supervision of this kind of illegal  building should be relatively low. At present, the type composition of  illegal construction has changed significantly. At present, demolition is  still the main means of government departments to control illegal  construction. However, in the reality of law enforcement, faced with the  behavior of upgrading and expansion, the single demolition method is  not very effective. The problems of demolition and reconstruction and  weak supervision often occur. In the process of law enforcement practice, the characteristics, changing trends and forming characteristics of illegal  buildings have a great impact on the effect of control measures. The  digital rule of law has a good targeted way to solve the existing problems, so this paper tries to start from the digital rule of law, to explore the  strategy to optimize the efficiency of law enforcement of illegal buildings.
