This paper investigates the impact of knowledge spanning and knowledge hierarchy on the appeal of questions in online knowledge markets. Using data from Zhihu.com, the authors find an inverted U-shaped relationship between knowledge spanning and question appeal, moderated by knowledge hierarchy. The inverted U-shape is more pronounced for questions with lower knowledge hierarchy (concrete questions), while it weakens and disappears for questions with higher knowledge hierarchy (abstract questions). The study contributes to knowledge recombination theories and offers practical implications for online knowledge market design.
