Partner selection has been a vital factor for the success of collaboration in platform-based innovation ecosystems, but few studies examine how to select in such ecosystems. Based on three cases, this study proposes a conceptual framework of two-stage partner selection for platform-based innovation ecosystems toward servitization. The analysis shows that: the stage I is a preliminary selection and aims to form an open “Resource Pool”, based on individual candidate's basic operation capability, platform compatibility and collaborative risk; the stage II is a combined selection of partners based on customers' demands, focusing on candidates' collaborative capability and sustainability capability. This study not only expands the scenario of partner selection in PIEs toward servitization but also appeals to how to select partners in PIEs, and it also offers guidance for manufacturing enterprises to implement the strategy of PIEs for servitization.

合作伙伴的选择一直是基于平台的创新生态系统中成功合作的关键因素，但是很少有研究探讨如何在此类生态系统中进行选择。基于三个案例，本研究为基于平台的创新生态系统向服务化提出了两阶段合作伙伴选择的概念框架。分析表明：第一阶段是初步选择，旨在根据候选人的基本操作能力，平台兼容性和协作风险，形成一个开放的“资源库”；第二阶段是根据客户需求组合选择合作伙伴，重点是候选人的协作能力和可持续性能力。这项研究不仅将PIE合作伙伴选择的场景扩展到服务化，而且还呼吁如何在PIE中选择合作伙伴，
