Platform ecosystems have captured a variety of markets, enabling coordination, transactions, and value co-creation between independent actors. A focal platform constitutes the central nexus of e-commerce ecosystems and fosters the interaction among ecosystem participants through their boundary resources. Standardizing these interfaces simplifies ecosystem entry for developers and increases the number of participants propelling the network effects, and thus the overall value of the ecosystem. Currently, there is a lack of prescriptive design knowledge guiding platform owners in designing successful e-commerce ecosystems. Addressing this issue, we followed a dual approach, reporting on a systematic literature review in which we identified design requirements and complemented these with a multiple-case study on selected e-commerce ecosystems. Aggregating the requirements resulted in six meta-requirements and 19 design principles that foster the standardization of focal e-commerce platforms. Our design principles simplify the development of complements and enable multi-homing for developers due to possible standardization across ecosystems.

平台生态系统已经占领了各种市场，支持独立参与者之间的协调、交易和价值共同创造。焦点平台构成电子商务生态系统的中心节点，并通过其边界资源促进生态系统参与者之间的互动。标准化这些接口简化了开发人员进入生态系统的过程，并增加了推动网络效应的参与者数量，从而增加了生态系统的整体价值。目前，缺乏规范的设计知识来指导平台所有者设计成功的电子商务生态系统。为了解决这个问题，我们采用了双重方法，报告了系统的文献综述，其中我们确定了设计要求，并通过对选定的电子商务生态系统的多案例研究来补充这些要求。汇总这些要求产生了 6 项元要求和 19 项设计原则，这些原则促进了重点电子商务平台的标准化。由于跨生态系统的可能标准化，我们的设计原则简化了互补的开发并为开发人员实现了多宿主。
