ObjectiveInterpersonal coopetition is characterized as simultaneously competing and cooperating towards the same social target. Growing evidence has suggested that competition and cooperation at the interpersonal level involve social comparison. The current study aimed to model the interplay between competitiveness, cooperativeness, and social comparison orientation (SCO).MethodWe implemented graphical Gaussian models across facet- and item-level to characterize the network structure and influential nodes using cross-sectional data from 1073 Chinese participants. We then estimated a directed acyclic graph to examine the probabilistic dependencies among the facets. In addition, we compare the gender differences of the facet-level GGMs.ResultsThe converging evidence demonstrates the significance of Surpassing and Willingness in the interpersonal coopetition network, with Ability facet of SCO playing a potential hub bridging competitiveness and cooperativeness. Furthermore, we found significant gender effects on competitiveness and cooperativeness and the relationship between their facets.ConclusionsThese findings provide a first coherent view of the interpersonal coopetition network and comprehensive insight into the symbiosis of competitiveness and cooperativeness within the framework of social comparison. Surpassing and Willingness are promising targets for preventing hypercompetition and require further evaluation.
