Abstract

Abstract: In order to comparatively analyze the basic building blocks of national emergency management systems across different countries,the NEOCN of China and of the U.S. (i.e., NEOCN-CHN and NEOCN-US) were constructed. The homogeneous and heterogeneous building blocks were comparatively investigated using the network motif method. Results show that the building blocks in the NEOCN of China and of the U.S. are characterized by homogeneous types of (anti-)motifs, as well as heterogeneous distribution of (anti-)motifs, and that the optimization of emergency organizational collaboration system needs to take into account both the identity in connotation between emergency network motifs and the difference in construction mechanism between emergency networks.

Key words: national emergency organizational collaboration network (NEOCN), building block, emergency management, network motif, complex network
