People have gradually realized that the world we live in,especially in the current times of the Internetand big data,includes not only a homogeneous Gauss world but also a heterogeneous Pareto world.Aiming at thedebates about the measurement of heterogeneity in the complex network circle,this paper first deals with the mea-ning,classification and basic measurement method of heterogeneity,and then regards the peer production communityof open- source software in the Internet as a new- type organization and hence reveal the heterogeneity of its organiza-tion structure through the heterogeneity meaning and relevant parameters of complex network,with a Codeplex C#community being taken as the example.Finally,the practical steps for analyzing the structural heterogeneity viacomplex network models are summarized,and the physical background and research significance of structural hete-rogeneity of organization are discussed.
