Analysis of mutualism between Tianjin port and Shij iazhuang dry port
摘要
Abstract
In the Beijing,Tianjin and Hebei integration background,in order to explore how should the port make its develop-ment strategy,the symbiotic relationship between Tianjin port and Shijiazhuang dry port is studied.Based on the basic theory and method of population ecology,the general population ecological model is improved,and the dynamic model which can reflect the relationship between Tianjin port and Shijiazhuang dry port is established.By using the nonlinear system stability theory,the condition for the existence of the positive equilibrium point of the system and the condition for the stability of the positive equilibrium point are analyzed.Then the condition for long-term stable development of Tianjin port and Shijiazhuang dry port is obtained.Combining with the actual situation of Tianjin port and Shijiazhuang dry port,the numerical simulation is carried out,and the simulation results are explained.The simulation results verify the correctness of the theoretical analysis. The research result is also suitable for the long-term stable development between other ports and their dry ports,and is the theoretical basis for the government and relevant departments to make decisions.关键词
