Artificial intelligence is gradually playing an important role in manyfields. With the development of artificial intelligence, the legal regulation ofartificial intelligence is extremely urgent. Because Artificial Intelligence does nothave the ability of declaration of will and the basis to bear tort liability, and thereis a conflict between the subject theory of Artificial Intelligence and the currentlegal system, the legal regulation of Artificial Intelligence should take the objecttheory. On this basis, attributing the tort liability of Artificial Intelligence toits producers can protect the rights of users and help improve the prudence ofproducers when producing. About the criterion of liability, according to thematurity of Artificial Intelligence technology in different periods, we shouldfirst adopt the principle of no-fault-liability and then take the principle of faultliability regulate Artificial Intelligence.
