从全球范围来看，2021年，开源整体呈现高速发展的趋势，越来越成为跨越国界和语言的共识。各国纷纷制定政策法规推动开源发展，依托开源构建广泛技术融合，形成开放发展模式，开源生态也逐步完善，开源也成为资本市场的新风口。开源蓬勃发展一方面推动了技术创新，另一方面考虑到国际竞争关系错综复杂，开源软件安全作为软件供应链安全的重要环节，面临着软件断供、安全漏洞、知识产权等问题与挑战。在现阶段积累的政策基础、技术基础、生态基础之上，开源将形成开放、平等、协作、共享的发展模式，加速软件迭代升级，促进产用协同创新，推动生态完善，成为软件技术创新的主导模式。
From a global perspective，in 2021，open source shows a trend of rapid development，which has increasingly become a consensus across national boundaries and languages. Countries have formulated policies and regulations to promote the development of open source，relying on open source to establish extensive technology integration and form an open development model. The open source ecology has been gradually improved，and the open source has become a new opportunities in the capital market. On the one hand，the vigorous development of open source promotes technological innovation. On the other hand，considering the complex relationship of international competition，the open source software security，as an important link of software supply chain security，is facing challenges such as software supply interruption，security vulne-rabilities，intellectual property rights and so on. Based on the policy basis，technological basis and ecological basis accumulated at this stage，the open source will form an open，equal，cooperative and shared development model，accelerate the iterative upgrading of software，promote the collaborative innovation of industry and application，promote the improvement of ecology，and become the leading model of software technological innovation.
