Knowledge spillovers is regarded as one of the main advantages of the open source community. However, the factors that affects the effectiveness and efficiency remain unexplored. By studying a large dataset covering 13,000,000 open source projects from Github, I document evidence supporting both the numbers of collaborators and social network structure of the developers drive the success of a project, which suggests the existence of both direct and indirect channels of knowledge spillovers. Meanwhile, I also find that the level of developer activity (as measured by number of comments) is critical for indirect spillovers.
