Study on the relationship between port cluster and regional economic development with SD

In the context of integration and network in port development, the relationship between port and city extends to be the ports and its region. Regional economic development will inevitably affect and promote its port development. At the same time, the role that port cluster play in regional economy growth will be increasingly strengthened for its rapid development. Besides, it more effectively promote regional economic development So it is necessary to study the relationship between port cluster and regional economic development. This paper first studies this interactive relationship qualitatively, then chooses system dynamics model, analyzing the characteristics of their coordinated development quantitatively in Zhejiang province. By changing three system parameters-the investment ratio in port, the collaboration coefficient and ROR in port cluster, we do the simulation between the economic development and port cluster in Zhejiang province, in order to make port cluster develop more rapidly. Finally, we put forward the corresponding proposals and countermeasures.
