Cooperation sharing distributions in some cooperation-competition systems

This online supplement mainly presents the details of empirical investigations of so-called "cooperation sharing" distributions in 12 real world cooperation-competition systems, which will be used for building an evolution model that will be reported elsewhere. All the distributions obey a function form P(\omega)(\omega+\alpha)^(gamma). The heterogeneities of the cooperation sharing distributions in different systems can be described by two distribution parameters,\alpha and \gamma. The empirically determined system evolution durations are also presented.
