Abstract: The open source ecology of cloud computing is gradually forming. Promoting innovation and managing risk have become important targets of open source operation and open source governance. Based on the evolutionary game theory, this paper builds the evolutionary game model among multi-stakeholders(cloud computing enterprises, industrial alliances and governments)under industry self-discipline mechanism and government supervision mechanism, and analyzes the key parameters influence on the strategies and benefits of the system. It is found that under the industry self-discipline mechanism, the liquidated damages and foundation subsidies will promote the cooperation of knowledge sharing, while the industrial alliances are more sensitive to the existence of risks. Under the government supervision mechanism, fines and subsidies can help participants balance risks and promote knowledge-sharing cooperation. The research results provide references for sustainable development of the open source ecology of cloud computing.
