移动的生态系统的模式正在迅速变化，特别是自智能设备的普及以来。新的重要参与者正在涌现，移动的生态系统的范围正在扩大，并侵蚀其他IT生态系统的技术边界。然而，鉴于现有的研究很少，我们对移动的生态系统的了解有限。因此，本文通过对移动的产业的专利引用分析，对企业间的技术知识流动进行计量，实证研究移动的生态系统的网络结构。我们发现，平台提供商正在成为生态系统中知识流活动的中心。通过引入一个新的网络指数，网络集中度指数，它测量了一个企业的知识集中率向子行业，我们还发现，每个平台提供商显示出独特的变化模式，在他们的技术知识网络，每个正在形成自己的子网络与关联企业的影响力增加。
The paradigm of the mobile ecosystem is rapidly changing, especially since the uction of smart devices. New important players are emerging, and the scope of the mobile ecosystem is expanding and encroaching on the technological boundaries of other IT ecosystems. However, our understanding of the mobile ecosystem has been limited given the few existing studies. Therefore, in this paper, we empirically examine the network structure of a mobile ecosystem by measuring the technology knowledge flows between firms based on a patent citation analysis of the mobile industry. We found that platform providers are emerging as the center of the knowledge flow activity in the ecosystem. By introducing a new network index, the Network Concentration Index, which measures a firm’s knowledge concentration ratio toward subsectors, we also found that each platform provider shows distinctive changing patterns in their technology knowledge network and that each is forming its own sub-network with increased influence on affiliated firms.
