Promoting shared leadership in teams and enhancing team creativity is aided by complementarity between leader and team member characteristics. We integrate insights from social learning theory and dominance complementarity perspective with the team leadership and creativity literature to explore the facilitating role of formal participative leadership for enhancing team creativity indirectly by promoting shared leadership. The relationships among formal participative leadership, shared leadership, and team creativity are bounded by team voice behavior and team creative efficacy. To test our theoretical model, we collected multisource and multiwave survey data from 382 members of 73 teams. Results revealed a significant positive relationship of participative leadership with shared leadership in teams, which in turn was positively associated with team creativity. Team voice behavior and team creative efficacy moderated these relationships, respectively, by strengthening the positive relationships. We discuss the theoretical contributions, practical implications, and future directions of our findings.

In the context of social commerce, the influence of culture on consumers’ behavior and attitude is more significant. This paper empirically analyzes the influence of social interaction (perceived risk, trust, and intimacy) on consumers’ purchase intention in social commerce, and the antecedent effect of cultural dimensions (uncertainty avoidance and individualism/collectivism) on social interaction is also explored. Data were collected in China and France from consumers who had prior online shopping experience on social commerce websites. The results show that the impact of perceived risk on subsequent purchase intention in social commerce will be transferred by trust and intimacy to a certain extent. The intimacy between users contributes to trust-building, and both of their positive impacts on purchase intention would show distinct effects in different cultures. Besides, cultural dimensions are proved to have a significant effect on users’ social interaction. Although high uncertainty avoidance brings perceived risk, it can promote subsequent trust-building. These findings help provide managerial insights for social commerce community to establish effective trust mechanism in a multicultural context.
