摘　　要：We propose investigating the node strength connectivity correlation by a resource-allocation method and the traditional multiple edge method, respectively. A rough analysis suggests that the resource-allocation node strength connectivity correlation is always negative, which is different from the connectivity correlation of the traditional multiple edge node strength （it can show either positive, negative or no correlation）. As examples, empirical investigation results for two rea/ world cooperation-competition networks （the 2004 Athens Olympic Games network and the mixed drink network） are presented. We believe that the resource-allocation node strength connectivity correlation can serve as a description of the relative crackajack distribution, which is a complementarity of the traditional multiple edge one.We propose investigating the node strength connectivity correlation by a resource-allocation method and the traditional multiple edge method, respectively.
