From the time when it came to power, the Chinese management mode has shifted to "ruling according to law." Domestic scholars have done a lot of discussion on the basic connotation and related concepts of governing by law. Most of these theoretical discussions are static and are an analysis and explanation of the actual situation. China's ruling turn is an inevitable choice of regularity within the ruling logic, and more of a dynamic choice. The study of the logic of governing by law can more clearly discover the law of development followed by China's way of governing. After this static analysis, the development route within the logic can be extracted. Combining the research results of academia, construct a dynamic mode of governing by law, find the subject, object and development path of governing by law, so as to clarify the reasonable boundary of civil rights, party power and country's power, coordinate the development relationship among the masses, parties and the state, and standardize the progressive process of the will of the people, the will of the party, and the will of the state.
