Abstract:

The development of the regional logistics industry plays an important role in the development of economic in the area around the Poyang Lake, and how to reduce logistics cost is the key of the industry. Thus, scientifically constructing a logistics network has a significant impact on the economic spatial pattern there. According to the characteristics of logistics system around lake, this paper puts forward the methods about hubandspoke logistics network based on traffic cost, and proposed the scientific analysis method considering the various transportation factors . The grid network analysis method is more scientific, and the method of potential energy is improved than the traditional model. In this paper,  thirteen indicators were selected to establish a logistics network evaluation index system, and identify for each research unit of corresponding logistics comprehensive strength index with two main factors was identified. According to the index,  the different levels of hub city were sorted and determined. Moreover, based on the weighted average travel time, the time cost for radiation limits of a hub city was measured by the potential energy model. Thus, it enabled the construct of hubandspoke logistics network in the area around the Poyang Lake. This study indicated that the logistics network had been formed in area around the Poyang Lake, with Nanchang for the first level hub city, Jiujiang, Nanchang County, Jingdezhen, Fuzhou, Zhangshu for the second level, and other counties for the third level. The space pattern of logistics network looked like Nanchang as the nuclear, and Jiujiang, Nanchang County, Jingdezhen, Fuzhou, Zhangshu as the five hearts in the area around the Poyang Lake. The radiation scope of Nanchang included all of the area around the Poyang Lake, and other five hub cities included the area around themselves. From the incidence of the logistics network, four main logistics axis had formed, such as Nanchang to Jiujiang, Nanchang to Jingdezhen, Nanchang to Fuzhou, and Nanchang to Zhangshu. It is concluded that the radiation limits of second and third level hub city matched well with their administration boundary. For overall distribution of different region, the level of logistics network showed that the north and western region was high, the south and east region was low, the central region was outstanding in the area around the Poyang Lake. Otherwise, the logistics network indicated that north area was not balanced, part of east area and south area was weak. Lastly, this paper puts forward optimizing policy suggestions to the development of hubandspoke logistics network for the area around the Poyang Lake
