According to the theory of data network effect, this study investigates the dual-pathway impact mechanism of a platform's artificial intelligence (AI) capability on the users' perceived value of tourism platforms through experienced user-centric design and perceived private privacy. A sample of 220 users from tourism platforms were surveyed using a two-wave survey method to test the hypotheses. The results indicate that the AI capability of a platform positively influenced perceived user value through experienced user-centric design, while negatively affecting perceived user value through perceived privacy risk. Additionally, the findings suggest that data stewardship strengthens the relationship between AI capability and experienced user-centric design. Unexpectedly, data stewardship also strengthens the relationship between AI capability and perceived privacy risk. We also discussed the theoretical and practical implications of the findings on the dual-pathway effect of platforms' AI capability, as well as suggestions for future research.
