Consumers are increasingly adopting mobile apps to make hotel reservations. Apart from attracting new users, hoteliers and Online Travel Agents (OTAs) devote great efforts to motivate customers’ continuous use of the apps. This study introduces Implicit Theories of Intelligence (ITI) as an antecedent of the intention to continue the use of apps and explores the underlying mechanism. This study draws from an online survey administered to 459 Chinese respondents to link ITI with continuance intention (CI). The findings show that incremental theorists of intelligence exhibited higher hedonic motivation (HM) and lower perceived risk (PR) in the use of apps than entity theorists of intelligence. HM positively predicted CI, whereas PR negatively predicted CI. Contrary to our expectation, the mediating role of effort expectancy was not supported. These findings offer meaningful implications to hoteliers and OTAs.
