Research On The Relationship Of Logistics Industry And Industry Structure Based On System Dynamics

In recent years, logistics based on modern technology has become a dominated industry in Chinese national economic structure. As learning from developed countries' experience, mutual reinforcement relationship exists between the development of logistics industry and overall economy. Rapid developing in economy accordingly would bring an urgent demand for civil logistics, and thus stimulate growth in the relevant industries, such as transportation, warehousing, distribution, communication and postal. On the contrary, as being in the forward part of the industry chain, the development of logistics industry will change the mode of economic growth, as well as the strong association with the insurance industry, information industry, tourism and so on. Thus, it is critical to make to logistics industry as a pillar position to fully development.From an overall perspective, a complex feedback system is shaped between logistics industry and regionally optimized industrial structure. Logistics industry, as an integral part of the industrial structure, is coherently stricted by other industries as well as plays a crucial role in promoting and adjusting industrial structure. In this system, there are factors like individuals, government environment and others, all of which are bonded to affect each other. The system can not develop into the better direction only when all of these internal factors coordinate well. Based on that, system dynamics, which is considered smart at dealing with complex systems problems, has been chosen as methodology in the paper to build system dynamics model of regional logistics industry and industrial structure optimization.Due to possess characteristic of heavy industry, the northeast region in China has been selected as the research object in the paper, which is aimed at verifying the model built on the logistics industry and structurally optimized industry by the method of system dynamics. By model simulation, the issue of development in regional logistics is able to be analyzed, as well as the calculation for the diverse contribution to GDD from various transportation investments is achievable. Thus, strategic recommendations are proposed on how to enforce the investment proportion in land transport, warehousing, postal infrastructure in order to stimulate the regional economy.
