Study On The Interactive Relationship Between Sichuan Exit Section Of The Yangtze River Shipping And Port Industry

To build golden waterways and Yangtze River economic belts is being paid more and more concern and attentions, while the main factors that affect its development are inland shipping and port industry. There are so many port industries both in domestic and abroad, and they have proved that the concentration and correlation effect have played a great role in promoting development of inland shipping during the development of port industry. Meanwhile, the further optimization of inland shipping is also a great push to port industry. In short, there exists a mutual influence and promotion between the inland shipping and port industry.Based on the research goal of mutual relationship between the inland shipping and port industry, this paper is trying to reveal the development mechanism of them, which including four subsystems such as the port industry, inland shipping, regional economy and employment. This paper also analyzes the endogenous power and external environment of the entire system to explore the relevance of inland shipping and port industry under the help of system dynamics, and by the software VENSIM, the results of inland shipping and port industry can be explicit and quantified.This paper is divided into three parts. Firstly, it makes theoretical and empirical analysis toward the development of inland shipping and port industry, then constructing the frame of dynamical systems with four individual modules, which contains the port industry, inland shipping, regional economic and employment aspects, researching system’s feedback loop of each module; finally, based on data and related theory in area Yangtze River of Sichuan, then studied each variable quantitative equation, building inland shipping of Sichuan area and port industry system dynamics model with VENSIM software, take 2013 as the starting year of the model, the object of study’s key variables economy, port handling capacity, temporary and fixed assets investment are predicted by the model, and on this basis of the investment from inland shipping, design policy from inland shipping investment, industry investment, economic growth, then simulating and analyzing different regulation of the results policy measures by the model, finally get the relationships of shipping and port industry.
