The study of the migration law and establishment of the migration model have great significance for stabilizing enterprises, coordinating development, formulating relevant park policies for the Government, and attracting enterprises into the parks. In this paper, an attitude space of logistics park and structure of logistics industry are set up, and a nonlinear dynamical model for park's enterprises is established. The gathering characteristics and law of the park's enterprises are also analyzed, on the basis of a case research on the migration of the park of logistics enterprises with Wuhan Danshuichi Logistics Park, which is laid out to prove the validity of the model. The method has great significance and reference for guiding the construction of urban logistics parks.
