Research Of Urban Freight Logistics Park Hierarchy

With the hot rise of logistics,logistics parks,ushered in the booming period of construction and development of gold in recent years.According to a 2015 promulgated “the fourth national logistics park survey results” show that our country existing logistics park(base)1210,increased by 60% compared with 2012.Has been put into operation the park 857,1.5 times than net three years ago.Bohai rim region,the Yangtze river delta and pearl river delta region are invested to speed up the planning and logistics nodes at all levels,including construction of logistics park planning is the key.But the construction of logistics park neglected the development of logistics node must be economy,the logistics market demand and transportation infrastructure limitations.Part of the large and medium-sized cities logistics park planning and construction area with regional economic development,planning and construction of optional the gender is big,caused the logistics resources can do its use.To begin a logistics park 1210,more than one-third of the park think facilities can't keep up with has become one of the bottleneck of the development;Nearly a third of the park there are irrelevant to the development of the local economy caused by the problem of insufficient capital;A quarter of the park is not allowed in the initial planning and scale hierarchy defines the garden,planning randomly,reserved to the problem of inadequate;22% of the park don't think its strategic position clear to its development.The question boils down to city level definition of logistics park is not reasonable.Li Ming,the President of the China federation of logistics and purchasing,said,in our country the concept of 'logistics park in logistics standard do not make clear definition and classification,around in the actual work is still a big different.Understand and grasp some of the local wholesale market,commodity distribution center,freight yard also eagerly with " logistics park hat".Therefore,this paper argues that for urban hierarchy of logistics park research is necessary.Reference literatures,in the “shallow discussion Guangzhou regional comprehensive logistics park planning and construction ”,put forward the logistics park can be divided into international hub of logistics park,regional distribution logistics park,xiamen city distribution logistics park,three kinds of logistics park corresponding to the level of the first,second and tertiary logistics park.Existing logistics node on the concept of generalized belong to the category of logistics park,therefore,in this paper,the research of unified logistics node to be classed as logistics park,its level according to the above ideas.However,evaluation criterion of divided city logistics park levels,there is no detailed study.Past research more concentrated in one province in China,the cities within the province of logistics the hierarchy of the city,the influence of the selected indicators are mostly macro,such as urban per capita GDP,per capita consumption expenditure,such as import and export trade and urbanization level indicators.In this article,based on city logistics park as the research object,the selected indicators has its particularity,such as surrounding the park road congestion,cargo throughput level,land availability,prudent degree of regional added value of service industry,traffic and the convenience of multimodal transport accessibility,is applicable to the hierarchy of in this paper.And road congestion is introduced in this paper,innovation index,the calculation of traffic access degree also abandon past road network density measure,the use of special way of calculation,this is due to the density of road network is generally city level indicators,and each park near within the scope of the road network density is difficult to estimate.This basis,this paper determines the index of 16,and have chosen Guangzhou representative 13 logistics park(part not currently named park,but it doesn't affect its hierarchical classification),according to the specific data index after the screening to select 14 indexes.Using domestic multifunctional DPS data processing system software,fuzzy clustering analysis and divided into four types of the most appropriate,and test the clustering results.Classification can not see the rank of each category accurately,this paper in the third chapter introduces the logistics contact strength between the nodes as a supplementary analysis after the classification,according to the size of the contact strength calculation and middle and the logistics development of the comprehensive score values determine the hierarchy of each class of separate zone height,will be the first and the second node to return for the level of logistics park,the third type of nodes as the secondary logistics park,the fourth class nodes classified as level 3 category of logistics park.Refer “the development of modern logistics in Guangzhou layout planning(2012-2020)”related content,this paper is verified logistics park general feasibility and applicability of hierarchy evaluation standard.
