Abstract The research aims to find the key causes and their relationships of express safety accidents. Based on the complex network theory, the Express Safety Accident Causation Network (ESACN) was constructed by setting factors as nodes and their relationships as arcs. There are 40 factors nodes extracting from personnel, express, equipment, environment, management and results. This study found that the ESACN is a small world network. Meanwhile the intermediary centrality is obvious and there is a 3-core high-density cloud in ESACN. The result indicates that casualties, express fire, express damage, property loss and transportation vehicle problems are the key factors in ESACN. Among these factors, the accumulation and damage of express have the most significant effect on accident risk transmission. The high-density correlation among the 15 factors plays a core role in the occurrence of accidents.
