Evolution and Current Landscape of Chinese Domestic Operating Systems
This article traces the early emergence of Chinese Linux‑based operating systems, analyzes the reasons for their limited market impact, outlines the recent ecosystem improvements and policy support, and reviews key players, CPU developments, and the unified strategy behind modern domestic OS solutions such as UOS and Kylin.
The 1990s saw the first Chinese Linux distributions—Red Flag, Xteam, Blue Point, and others—emerging shortly after the global rise of open‑source kernels, but most failed to achieve lasting market influence due to fragmented ecosystems and limited resources.
Four major shortcomings hindered earlier domestic OSes: immature hardware/software ecosystems, insufficient market mechanisms, lack of sustained innovation, and a fragmented industry landscape, leaving only a few survivors like Kylin, Deepin, and UOS.
Since 2015, policy initiatives such as the "Nuclear‑High‑Base" project have strengthened the hardware foundation, enabling CPUs like Loongson, Phytium, and Huawei Kunpeng to reach usable performance levels and support a growing OS ecosystem.
Key companies now drive the market: UnionTech (UOS) promotes a unified "six‑unified" strategy covering version, platform, app store, interfaces, standards, and documentation; Deepin (by Wuhan Deepin Technology) offers a user‑friendly desktop and strong open‑source contributions; and Kylin Software (merged from China Software and Tianjin Kylin) delivers enterprise‑grade OS, cloud, and high‑performance‑computing solutions.
These vendors emphasize security, standardized development interfaces, and comprehensive service ecosystems, positioning Chinese operating systems for broader adoption in government, finance, and industry while fostering a more consolidated and competitive market.
