This article examined whether two prominent characteristic of Chinese self-construal, contingent orientation and constrained autonomy, were related to their prevalent buffet preferences. Findings in a panel survey revealed that participants' contingency was positively correlated with their buffet preferences, whereas autonomy was negatively correlated with this diet preferences. Moreover, the results showed that participants' prior contingency and autonomy could predict their subsequent buffet preferences over a half-year period. Data from an experimental study showed that the lower autonomy participants perceived; the higher buffet preferences evoked. The results provide insights into market segmentation and strategy innovation in the international diet market.
