报告人简介：

      陈晓梦于2023年毕业于康奈尔大学SC约翰逊商学院并获得应用经济与管理博士学位，现为匹兹堡大学商学院的助理教授。她的研究聚焦于网络平台，特别是知识分享型平台，聚焦不同平台策略和组织架构对平台整体结果（用户贡献、知识分享效率等）的影响。研究运用计量经济学方法和实验，来识别平台决策的因果效应，并评估特定的平台选择是否能带来积极的结果。

报告内容简介：

    This paper studies platform bifurcation, where a subgroup of users from the original platform launches an independent spin-off platform. We identify the effects of bifurcation using a DID approach, which exploits the introduction of spin-off platforms in an online platform incubator. We find that bifurcation leads to a strong overall increase in contributions. While contributions in the home platform decline, the two bifurcated platforms generate more combined user contribution and attract more new users compared to a single united platform. We further explore how interconnectivity and platform differentiation affect users’ platform choice. Our evidence indicates that users are less likely to migrate from an incumbent platform to a new specialized platform when the interconnectivity is strong. However, users are more likely to migrate when the specialized platform enables more differentiation. This paper is the first to empirically analyze the strategic implications of new platform emerge at scale and to document the moderating role of interconnectivity and platform differentiation.
