Yangtze River Policy Research Based On Systems Dynamics

Yangtze River is a waterway channel which passes our country through east to west, it contains huge transport capacity resources, has the huge water transport scale. Although the Yangtze River shipping promoted our country economic development, but the Yangtze River shipping market has some problems. How to guide development of the Yangtze River shipping in highly effect, order and use existing resources reasonably, satisfy the need of state economy development, is the key question to Yangtze River shipping policy research.The Yangtze valley is distributing our country's important industry belt, the river the economic region has big transportation demand. With the further economical development and quickening global economic integration process, the Yangtze River basin formed obvious region characteristic industrial layout, this ensures the Yangtze River shipping has sufficient source of goods, provides safeguard for the Yangtze River shipping's development. The Yangtze River shipping becomes bigger and bigger function in the economical layout and development, also in our country's west big development, middle rising and eastern's realizing in the modernized strategy. It will become core area where economical layout and the economy is soaring. Our country is in the initial stage of market economy development, the trade management department's function has some transformation, but it still fells behind transports market development in the macroscopic management. At present, the Yangtze River shipping is facing a significant change in route improvement, ships standardization, shipping mechanism and so on. With the in-depth development of market economy and increasing competition, the State made the "12th Five-Year Plan", development to the Yangtze River. At the same time, all local governments along the Yangtze River have formulated a series of local policies to promote the development of local shipping, on the basis of which the Yangtze River will become into a smooth and efficient transport system of river and sea. As the basis of the unified planning and effective coordination, the Yangtze River shipping will present a unified, open, competitive and orderly market environment. Researching related shipping policy will help enterprises reduce operating costs and improve operational efficiency and make full use of a variety of shipping resources to achieve maximum economic benefits.This article introduces development process and the present condition of the domestic and foreign shipping policy, summarizes basic connotation to the Yangtze River shipping policy research, limites the scope to Yangtze River shipping policy research, determines this article's research method basing on the Yangtze River shipping system's characteristic. Takeing the systems dynamics theory as the foundation, analyzes the Yangtze River shipping system's essential factor and characteristic, constructes dynamics model to the Yangtze River shipping systems through analyzing system causal relation. It simulates the shipping policy's influence to the Yangtze River shipping by the study object Wuhan Yang Sigang port, obtains the feasible harbor development policy plan. It proposes the related Yangtze River shipping policy suggestion that has provided certain reference value for the Yangtze River shipping's development.
