functions and powers of the state

State function is a state machine, which is the direction of activities to achieve the general task and purpose of the state, or the general direction and role of state activities. Western political scholars usually call the national function as the national function, or describe the activities, specific tasks and forms of national activities of each component of the country as the national function.

If someone says that the state function is the function of individual state organs, it is said that the state has the functions of legislation, justice and management. There are at least three purposes to describe the national function as the specific purpose of national activities: ① to protect the country from infringement by other countries; ② to protect everyone in the country from infringement and oppression by others; ③ to hold events that individuals or a few people should not or cannot hold.

Others say that the country has four purposes: security, rule of law, economy and culture, or five purposes: security, order, morality, freedom and welfare. Marxism holds that the function of the state is the concrete embodiment of the essence of the state and serves to solve the basic contradictions of the society.
