Platform designers create and implement incentive systems to encourage users to contribute content to online communities. This article examines the effect of a multidimensional incentive hierarchy in motivating users to engage in competitive and prosocial activities. Utilizing an external change observed in the data science community, Kaggle, and applying a quasi-experimental design, we compared users’ engagement levels before and after introducing a multidimensional incentive hierarchy. We found that implementing a multidimensional incentive system directed users from submitting answers to Kaggle competitions to participating in Kaggle’s online forum discussions. However, our additional analyses suggest that the most and the least motivated users may be less likely to be impacted by such incentives.

包容性激励制度是否鼓励在线社区中的亲社会或竞争行为？

平台设计者创建并实施激励系统，以鼓励用户向在线社区贡献内容。本文研究了多维激励层次在激励用户参与竞争性和亲社会活动方面的效果。利用在数据科学社区 Kaggle 中观察到的外部变化，并应用准实验设计，我们比较了引入多维激励层次结构前后的用户参与度。我们发现，实施多维激励系统会引导用户从提交 Kaggle 竞赛答案到参与 Kaggle 在线论坛讨论。然而，我们的额外分析表明，最积极和最不积极的用户可能不太可能受到此类激励措施的影响。
