Supervisor-subordinate guanxi is an informal leader-member relationship that is of utmost importance in Chinese organizations. This paper explores Chinese employees' motives for building supervisor-subordinate guanxi through two studies. Study 1 develops an indigenous scale of motives for supervisor-subordinate guanxi. Four motive types (i.e., career advancement, team concern, personal life, and impression management) are identified, and the scale's convergent and discriminant validity is established. Study 2 examines the predictive power of these motive types. The results indicate that they, as a whole, account for unique variances in supervisor-subordinate guanxi. Furthermore, as single motive types, they have unequal impacts on this relationship and its dimensions. This research enhances understanding of what underlies supervisor-subordinate guanxi from a motivational perspective and has implications for Chinese indigenous research of guanxi.
