Abstract: In order to reveal occurrence mechanism of work safety accidents, coupling and risk transmission features of accident causation factors were analyzed from a perspective of complex system. Then, a causation network model in a district of Beijing was constructed by complex network theory. Distribution characteristics of nodes were studied by calculating statistical indexes such as node degree and modularity, and key factors and community structure with close connections among factors in the network were identified. The results show that a few key factors play an important role in network structure, including lack of safety education and training, illegal operation and unsound construction plan, etc, and there exists obvious community structures. Safety management can be improved effectively and accident rate reduced by taking targeted control measures for key factors and high-density sub-networks to obstruct transmission of risks in the network.

Key words: complex network, work safety accident, accident cause, risk transmission, modularity
