This study aimed to validate a structural model of smart Tourism by examining the impact of multiple technological, behavioral, and managerial constructs on the development of smart Tourism in Kish Island, Iran. The research employed a quantitative design using a descriptive-correlational strategy and structural equation modeling (SEM) to evaluate the proposed model. A two-stage sampling method was applied: first, cluster sampling was used to randomly select 30 hotels from 51 active establishments in Kish Island,second, simple random sampling was used to select tourists from these hotels. Out of 311 distributed questionnaires, 273 were deemed valid and analyzed. A 45-item smart Tourism scale developed by the researchers was used for data collection, with its content validity confirmed by experts (CVI = 0. 82). Cronbach’s alpha, composite reliability (CR), average variance extracted (AVE), and discriminant validity tests were conducted to ensure measurement reliability and validity. Data were analyzed using SPSS-24 and SmartPLS-3. All eight independent variables—perceived value, economic development, smart technology, tourist behavior, complementary activities, destination capability, information management, and smartification—had statistically significant effects on smart Tourism. Smart technology (β = 0. 269, p < 0. 001) and economic development (β = 0. 199, p < 0. 001) showed the strongest influences. model fit indices, including AVE (>0. 50), CR (>0. 70), and goodness-of-fit (GOF = 0. 725), confirmed the model’s validity and predictive power. Discriminant validity was also established using the Fornell-Larcker criterion. The validated smart Tourism model demonstrates that technological infrastructure, managerial readiness, and tourist-centered strategies are essential for developing smart Tourism destinations. These findings offer both theoretical insight and practical guidance for enhancing Tourism innovation, competitiveness, and sustainability in similar regional contexts.
