This article aims to investigate the cross-cultural differences of moral intensity and upward influence strategies by comparing 344 usable responses of tourism MBA students from India, Korea, and Taiwan. The MANOVA results demonstrate the existence of significant differences on some dimensions of self-oriented moral intensity and the choice of upward influence strategies across the three groups. Specifically, Korean informants are more likely to apply various influence strategies and reveal moral intensity than the MBA students from the other two countries. We also utilized canonical correlation analysis to examine the effect of cultural background on the relationship between the dimensions of moral intensity and the choice of upward influence strategies. The results indicated that the sets of moral intensity measures and upward influence strategy measures are correlated in Indian and Taiwanese groups. However, this relationship was not supported by the data collected from Korean participants. This study has confirmed the moderating effect of cultural background on this relationship, but more research for further exploration is required in the future.
