This study focuses on the trend of "foreignization" of domestic snack brands and the upgrading of health consumption. It incorporates nutritional labels into the research framework of brand foreignization and adopts a discrete choice pre-experiment combined with eye-tracking to break down multidimensional foreignization attributes and generate choice tasks based on a zero-prior experimental design. The aim is to explore the interactive effects of visual attention, verify the feasibility of the experimental paradigm, and lay a methodological foundation for subsequent formal research.
