该研究探讨了众包竞赛中明星选手的参与对接包群体规模的影响。根据社会传染理论，实证结果显示明星选手的参与显著促进了竞赛者的参与和提升了接包群体的规模。这表明社会传染是众包竞赛中群体形成的主要机制。然而，在涉及多位明星选手的竞赛中，当我们考虑了竞赛参与者在技能水平、参赛经验（即与明星选手共同参赛经历）和文化背景方面的异质性时，明星选手的参与对群体规模产生了负面影响。此外，这种负面影响会随着明星选手与同一竞赛中其他接包方之间的技能差距、同场竞技次数和文化相似度的增加而加剧。该研究为发包方和众包平台管理者在设计竞赛任务以及管理竞赛的群体规模等方面具有一定的指导意义。

This paper examines the impact of superstars’ participation on the crowd size in crowdsourcing innovation contests. Based on social contagion theory, empirical results reveal that superstars’ participation positively affects the crowd size of a contest in general. This finding suggests that social contagion is a fundamental mechanism underlying crowd formation in crowdsourcing contests. Our results also indicate that in contests involving multiple superstars, superstars’ effect on crowd size becomes negative when we simultaneously consider other solvers’ heterogeneity regarding skills, exposure, and cultural background. This negative effect will be intensified by increases in the skill gap, extent of exposure, and cultural proximity between superstars and other solvers in the same contest. Our research is meaningful for sourcing managers and platform supervisors to design contests and supervise crowd size in crowdsourcing contests.
