Study of evolutionary mechanism of peer production community based on complex network

The paper reveals the preferred mechanism is a significant evolution characteristic of peer production virtual community by the analysis on static structure and dynamic evolution of virtual community.It builds the cooperation network of peer production virtual community based on Wiki voting administrators behaviors.It analyzes the in-degree and out-degree distribution.The result shows that the out-degree follows power law distribution and the in-degree follows two-stage power law distribution.It applies the link prediction method to sort the potential connection of the network,and it finds that PA index has higher scores than any other indices and the preferred mechanism plays an important role in the network formation process.
