The Development Research Of Qinhuangdao City's Port And City System Based On System Dynamics

"City is prospered by port, and port is used by city", which is a universal law in the development of port cities within the world, that is, both developments of the port and city are complementary. Thus, people pay more attentions to handle the relationship between the port and city. The aim of this paper is to find ways to improve Qinhuangdao City's Port and City System (PCS). And through this research, this paper can provide theoretical guidance and decision support for the better coordinated development of Qinhuangdao City's PCS.Firstly, this paper comprehensively elaborated domestic and foreign scholars'research status on two aspects: the one was the relationship between the port and city, the other was the comprehensive evaluation of the port economic development. Based on these research results, this paper enriched and perfected the Theory of PCS. Then this paper outlined the PCS'definition and features, and also specified the PCS'structure and functions.Secondly, this paper inspected the development status of Qinhuangdao City's PCS. Then it plotted out internal subsystems of Qinhuangdao City's PCS and chose operable performance indexes to set up an integrated performance indexes system which suited Qinhuangdao City's PCS.Thirdly, this paper used a method of System Dynamics (SD) to establish a simulation model of Qinhuangdao City's PCS, then, it took three different policy programs to dynamically simulate this model. Under the conditions of the three different programs'dynamic simulations, this paper comprehensively compared and analyzed different variables which mainly existed in Qinhuangdao City's PCS. Then this paper got the better programs to promote the coordinated development of Qinhuangdao City's PCS under the limited conditions.Finally, according to results of the model and the actual development status of Qinhuangdao City's PCS, this paper found ways and means to promote the better coordinated development of Qinhuangdao City's PCS, which was mainly from six aspects, that is, watercraft investment,lingang industrial,industrial structure,interim trade,port resources,port management information and people-oriented management.
