System dynamics analysis on the evolution of logistics cluster

Based on the theory of system dynamics, a dynamic model of various factors affecting the evolution of logistics cluster is established through the casual loop diagram. seven model variables have been identified. To this end, the entry, exit and growth of firms within logistics cluster is modeled and studied with the help of simulations. At last, the paper makes a preliminary numerical experiment. The results reveals the validity of the model which better understands the evolution of logistics clusters in the logistics networks and nodes in the Yangtze River Delta of China.
