The basic principle of system theory is the overall concept of the system, that is, treating the object studied and processed as a system.

any system is an organic whole, it is not a mechanical combination or simple addition of all parts, and the overall function of the system is a property that all elements do not have in an isolated state. He used Aristotle's famous saying that "the whole is greater than the sum of parts" to illustrate the integrity of the system, and opposed the mechanistic view that the performance of elements is good and the overall performance must be good, and the whole is explained by parts.

By analyzing the structure and function of the system, studying the interrelation among the system, elements and environment, and optimizing the system viewpoint, everything in the world can be regarded as a system, which is ubiquitous. The vast universe, the tiny atoms, a seed, a swarm of bees, a machine and a factory are all systems, and the whole world is a collection of systems.

The emergence of system theory has profoundly changed the way of thinking of human beings. In the past, when studying problems, things were generally broken down into several parts, and the simplest factors were abstracted, and then complex things were explained by the nature of some parts.

System theory reflects the development trend of modern science, the characteristics of modern socialized mass production and the complexity of modern social life, so its theories and methods can be widely used. System theory provides a methodological basis for solving various complex problems in politics, economy, military affairs, science, culture and so on in modern society, and the concept of system is infiltrating into every field.
