摘　　要：在对大众生产特征进行归纳的基础上,对大众生产的稳定性进行了分析,并进一步刻画了大众生产系统在不同结构下的临界特性。采用基于复杂网络的Ising模型,对大众生产系统的稳定性采用均场理论的方法推导了不同复杂网络结构下的系统临界点。采用Monte Carlo方法对图书推荐网、校内网等大众合作生产网以及经典的BA网络进行仿真,验证了均场理论关于系统临界的一些结论,并证明了系统临界态的出现与网络拓扑和外部因素密切相关。Based on the summary of peer production characteristics,the system stability was analyzed.And then,critical characteristics under different network structures were depicted.Critical points under different complex network structures were deduced by network-based Ising model,which take advantage of the mean field theory for certainty of peer production system.Monte Carlo method was used to perform simulation on three different peer production collaboration networks.Then,some conclusions of mean field theory relating to system critical points were verified.It also revealed that the system critical state was closely related to network topology structure and external factors.
