%X To characterize the scale-free feature of complex network quantificationally, the concepts of node-importance, network structure entropy and standard network structure entropy are proposed. The relation between the network structure entropy and the degree distribution is expounded. The network structure entropy of random graph and scale-free network is compared through the example of world trade web. Finally it is indicated that the network structure entropy will be an important tool to research the complex network.
