Abstract: In response to the urgent need for large-scale open collaboration and resource sharing between distributed enterprises under the cloud manufacturing mode， this paper combines evolutionary game theory to establish an incentive mechanism for resource sharing in a distributed environment， and analyzes the evolutionary game trend of resource sharing in different situations. It can be known through theoretical analysis and simulation experiment that total shareable resources， resource sharing level， resource utilization capacity， synergy benefit coefficient， evaluation benefit coefficient， sharing incentive coefficient and speculative penalty coefficient play positive roles in promoting the resource sharing， while the shared cost coefficient plays a negative role and direct benefit level has no effect. There is an inverted U-shaped relationship between the allocation coefficient of synergy benefit and the stable state of resource sharing evolution. This study provides references for promoting distributed resource sharing and accelerating industrial innovation in the future cloud manufacturing mode.
