With the rapid progress of digital technology and new business models’ development, the platform ecosystem has not only penetrated every sector in society but also revealed various problems. Platform governance researchers have highlighted its significance, but failed to adequately consider ecosystem participants’ behaviour. This paper aims to explore platform governance’s effects on enterprises’ behaviour in a multiorganisational platform ecosystem context. The tripartite evolutionary game is chosen to construct a mathematical model that integrates the government, platform organisation, and internal enterprises to analyse formal and informal governance’s influence on enterprises’ behaviour in the platform ecosystem. It was discovered that both formal and informal governance can decrease internal enterprises’ opportunistic behaviours. Furthermore, formal governance has stronger effects than informal governance, although informal governance’s effects are more stable. Additionally, self-organisation in the platform ecosystem is another important area of focus. This paper enriches an understanding of platform ecosystems while formulating insights relevant in using platform governance to develop small and medium-sized enterprises.

平台生态系统中企业行为的三方进化博弈分析

随着数字技术的飞速发展和新业务模式的发展，平台生态系统不仅渗透到社会的各个领域，而且还暴露出各种问题。平台治理研究人员强调了它的重要性，但是没有充分考虑生态系统参与者的行为。本文旨在探讨平台治理在多组织平台生态系统环境中对企业行为的影响。选择三方进化博弈来构建一个数学模型，该模型将政府，平台组织和内部企业集成在一起，以分析正式和非正式治理对平台生态系统中企业行为的影响。人们发现，正式和非正式治理都可以减少内部企业的机会主义行为。此外，尽管非正式治理的影响更为稳定，但正式治理的影响要大于非正式治理。此外，平台生态系统中的自组织是另一个重要的关注领域。本文丰富了对平台生态系统的理解，同时形成了与使用平台治理发展中小型企业有关的见解。
