This study attempted to confirm the effect of the user's characteristics on perceived ease of use, perceived usefulness, willingness to pay, flow and addiction to OTT service platform iQIYI users. Researchers believe that as the number of OTT service users who are willing to pay increases, research on the influencing factors and the cause of addiction is needed. As a result of the study, first, it was found that perceived usefulness affects willingness to pay, second, use intention and willingness to pay affect flow, and third, willingness to pay and flow affect addiction. This study considered that it has theoretical and practical value in that the route to flow and addiction of OTT service users was set and tested with intention to use and pay. Researchers hope that the study will expand in terms of willingness to pay and use experience of OTT services in the future.
