As in every field, the impact of artificial intelligence on legal relations and disputes is inevitably increasing day by day. Commercial Law, which deals with commercial relations, closely follows this impact in many branches. This section addresses the relationship between the basic concepts and institutions of Commercial Enterprise Law and artificial intelligence. In particular, it will be attempted to explain how artificial intelligence affects the concepts of commercial enterprise, commercial transaction, merchant, their provisions and consequences, dependent merchant assistantship, current account contract and unfair competition relationship with a normative legal approach. In this context, theoretical explanations and discussions regarding the definition and nature of artificial intelligence and its applications, which are explained in detail in the book chapters, are not included. Our explanations have been enriched by taking into account both national and foreign legal literature and court decisions. Issues where conceptual conflicts exist in national and foreign law comparisons have been excluded.
