Abstract:Open source, as an innovative production model characterized by openness and sharing, has become a core driving force for innovation, openness, sharing, and sustainable development in the digital economy. This study explores the significant value of open source from four dimensions:technological innovation, industrial development, economic contribution, and social sustainability. The current global open source ecosystem is showing a positive development trend, with a continuous increase in the number of open source projects and the scale of contributors. In China, open source efforts are gradually gaining momentum in emerging technology fields. Looking ahead, open source projects are expected to follow the spiral law of technological development, establish de facto global standards for both software and hardware, promote the application of open source models across industries, and take solid steps in risk governance. Finally, this study provides recommendations for the development of the open source ecosystem, including enriching open source operation models, strengthening international cooperation, and promoting the social application of open source to sustain the prosperity of the open source ecosystem.
