Abstract: The tourism programs designed by the Department of Tourism were used to study the selection behavior of people. Our results showed that people's behavior did not reflect the full rationality assumed by economic theory, and people's behavior appeared an irrational choice under some circumstances. Economic factor is only one thing that affects human behavior, among a great deal of influencing factors such as income levels, consumer preferences, system design constraints and so on. Thus, great importance should be attached to the “People and their behavior” in the economics research.
