The illegal behavior refers to the violation of the provisions of the current state law, endangering the social relations protected by the legal institutions of the law. According to the severity of the situation is divided into general violations and serious violations (i.e., criminal acts). According to its violation of the law, can be divided into administrative violations, civil violations, criminal violations and unconstitutional acts. Violation of the law is the violation of existing laws, causing some harm to society, the behavior of fault. Violations of the law are divided into general violations and serious violations (i.e., criminal acts) according to the severity of the situation. According to the violation of the law, can be divided into administrative violations, civil violations and criminal violations.

The concept of violation of the law has a broad and narrow sense. Violation of the law in the broad sense refers to all violations of existing legal provisions, including general violations and crimes. In the narrow sense, it refers to acts that seriously violate the law but do not constitute a crime. We are here discussing offenses in the broad sense.

The link between violation of law and crime is that crime is necessarily a violation of law and violation of law is not necessarily a crime. The difference is that the degree of social harm of the crime is more serious than that of the offense, most of the criminal acts are criminally liable, and the illegal acts bear administrative or civil liability.

There are differences between illegal behavior and some other behaviors. First of all, illegal behavior is different from the violation of morality. Many illegal acts, which are criminal acts, are also violations of morality. However, not all offenses are moral violations. Similarly, some moral violations do not constitute infractions. Second, an offense is different from a legally invalid act. Of course, a violation of the law can not occur when the perpetrator of the violation of the law for the law of the legal institutions of the validity of the desired result. However, can not be considered legally invalid behavior are illegal. Some legally invalid acts have no legal effect, but also does not constitute a violation of the law.

Administrative violation refers to the administrative subject of administrative law norms, infringement of administrative relations protected by law has not yet constituted a crime of the fault of the administrative act.

Administrative violation of law in a broad and narrow sense, the narrow sense of the administrative law only refers to the administrative subject of the law, the broad sense of the administrative law also includes the administrative relative to violate the law. We adopt the narrow sense. Accordingly, the administrative violation refers to the administrative subject violates the administrative legal norms but has not yet constituted a crime and is subject to administrative liability according to law. This concept reflects the three major features of administrative law:

1. Administrative law is the administrative subject of illegal. Unlike civil and criminal violations, administrative violations are administrative subjects in administrative law. Any organization and individual can constitute an administrative violation only when they appear as administrative subjects or in the name of administrative subjects.

2. Administrative violation is a violation of administrative law norms has not yet constituted a crime. First of all, the administrative violation of law, it violates the administrative laws and regulations, infringement of administrative relations protected by administrative law, and thus has a certain degree of social harm; Secondly, the administrative violation of law in the nature of the general law, the social harm is small, has not yet reached the level of crime.

3. Administrative violation is the law must bear administrative responsibility. Administrative law is a violation of administrative law norms and in accordance with the provisions of the law should bear administrative responsibility.
