This study examines the association among relationship types, their strength, and contribution behavior in reward crowdfunding. We analyzed data on 568 relational dyads between fundraisers and backers from successful campaigns on KarolinaFund. We collected data from fundraisers and classified the relations they had with backers before the campaign, and their strength. Our findings show that pre-existing relations contribute to a greater extent than previously unknown backers. Among backers with whom relations exist prior to the campaigns, those that have stronger relations with the fundraiser make higher contributions. Strength of relations negatively moderates the association between purely private relations and contribution extent, and positively moderates the association between professional relations and contribution extent. When comparing sub-samples of early and late contributors, we find that private relations contribute to a significantly greater extent at earlier stages, and professional relations contribute to a significant lesser extent in later stages.

关于关系类型、其强度和奖励众筹支持者行为

本研究探讨了奖励众筹中关系类型、关系强度和贡献行为之间的关联。我们分析了 KarolinaFund 成功活动中筹款人和支持者之间 568 个关系二元组的数据。我们收集了筹款者的数据，并对他们在竞选前与支持者的关系以及他们的实力进行了分类。我们的研究结果表明，预先存在的关系比以前未知的支持者的贡献更大。在活动之前就存在关系的支持者中，与筹款活动关系密切的支持者会做出更高的贡献。关系强度负向调节纯私人关系与贡献程度之间的关联，正向调节职业关系与贡献程度之间的关联。当比较早期和晚期贡献者的子样本时，我们发现私人关系在早期阶段的贡献程度显着更大，而职业关系在后期的贡献程度显着较小。
