Abstract:The digital public goods institutions are important foundations for promoting the development of an open source innovation ecosystem, which helps to break the key limitations faced by China’s open source innovation ecosystem, such as the lack of unity in technology routes and concentration of R&D power. Based on discussing the significance of improving digital public goods institutions, this study reviews the experience of major countries in the world in building digital public goods institutions and analyzes the prominent problems faced by the construction of China’s digital public goods institutions. This study points out that China’s open source innovation ecosystem faces problems such as a relative lack of digital public goods laws and regulations, insufficient improvement of the operation mechanism of digital public goods, and insufficient independent innovation of key digital public goods, which seriously impedes the high-level and sustainable development of the open source innovation ecosystem. It is urgent to accelerate the construction of digital public goods institutions from the construction of laws and regulations, the improvement of operation and management mechanisms, and the feedback of enterprises to the ecosystem and other dimensions to support the development of an open source innovation ecosystem.
