Urban Event Tourism, also a Resource for Inhabitants. The Case of the Champs-Élysées Christmas Market. Increasingly, events are used by cities to attract tourists and encourage them to return. Their expenses allow inducing an economic dynamic that can benefit residents. Moreover, residents sometimes participate in the organization of these events. The purpose of this article is to show that if urban event tourism is a resource for tourism, it is also a resource for the residential system, making them mutually complementary. The analysis is illustrated by a survey conducted on the Champs-Élysées Christmas Market from December 7, 2015, to January 10, 2016. A total of 800 questionnaires were collected. Their analysis shows the significant presence of Île-de-France residents compared to international tourists and excursionists, in a period marked by terrorism. The analysis nevertheless highlights that motivations and practices relative to expenses are different, but complementary. It can thus be concluded that urban events cannot be conceived exclusively neither for tourists nor for residents.
