Evaluation And Spatial Pattern Of Urban Logistics Competitiveness In Guangxi

Urban logistics is an important part of modern urban economy.Urban logistics not only greatly promotes the rapid development of regional economy,but also plays an significant role in urban spatial planning.With the advent of the modern logistics era,the traditional research has been unable to meet the needs of modern logistics development.Therefore,based on the big data background,this paper studies the competitiveness and spatial pattern of urban logistics in Guangxi,uses the relevant theories of urban geography and economic geography,collects the POI data and traffic network data of Guangxi in 2011,2015 and 2019,and uses the entropy method Cluster analysis,spatial interaction,weighted average travel time model and logistics gravity model are used to study the logistics competitiveness level and spatial distribution characteristics of cities in Guangxi.(1)The regional development of urban logistics in Guangxi is uneven.Taking Guilin Liuzhou Nanning line as the boundary,the density distribution of logistics enterprises varies greatly from east to west,and the POI data of logistics enterprises presents an "L" distribution as a whole.The logistics enterprises in the central region have a large agglomeration area,while the logistics enterprises in the western region are sparsely distributed as a whole,so a large-scale logistics agglomeration area with obvious agglomeration effect has not been formed.(2)Through the difference of traffic comprehensive weighted traffic time in Guangxi,we can reflect the advantages and disadvantages of traffic accessibility and the competitiveness of logistics infrastructure.The research shows that the four cities with the highest traffic accessibility and the best location conditions in Guangxi are Laibin,Guigang,Nanning and Liuzhou.Due to the influence of geographical spatial location,terrain and road density,the traffic accessibility intensity of Guangxi shows a spatial layout of high in the middle and low around.(3)According to the comprehensive evaluation index and cluster analysis results of urban logistics competitiveness in Guangxi,the 14 cities in Guangxi are divided into different grades,and the logistics competitiveness of all cities in Guangxi is divided into four regions,namely: Strong logistics competitiveness(Nanning),secondary logistics competitiveness(Liuzhou,Guilin,Yulin),logistics competitiveness in the middle(Qinzhou,Guigang,Fangchenggang,Beihai)and logistics competitiveness(Wuzhou,Baise,Hechi,Hezhou,Laibin,Chongzuo).Nanning’s logistics center position is unshakable,and in constant strengthening.At the same time,it is found that the competitiveness level of urban logistics in Guangxi is relatively scattered and the development is not balanced.The distribution pattern was high in the south and low in the northwest.The result of cluster analysis shows that most cities in Guangxi are located in the middle and weak areas of logistics competitiveness,which indicates that most prefecture-level cities in Guangxi have poor logistics development foundation and low economic development level,which leads to their weak logistics competitiveness.(4)Based on the logistics gravity model,the spatial interaction of various cities in Guangxi is analyzed,and it is concluded that the urban logistics spatial gravity value of Guangxi is low as a whole;The spatial relationship between cities in Guangxi is not close enough.There are 182 gravity values in 14 cities,and the total gravity value is only 100.53,which is in a relatively discrete situation,and the relationship between cities needs to be strengthened;Nanning has a prominent position in the center of the city,with remarkable characteristics of high primacy;The logistics development of some cities presents group development.(5)Guangxi city logistics competition ability difference and its formation reason.By means of weighted average travel time method,entropy method and space interaction method,the main factors affecting the competitiveness of guangxi city logistics are found.It is found that the level of economic development,infrastructure and location conditions,logistics enterprises and logistics personnel are the main influencing factors.The analysis of time series shows that the gap of logistics competitiveness of different cities has a tendency to expand,and we should strengthen the support to the competitive weak areas.(6)Suggestions about guangxi city logistics competitiveness and space optimization: based on economic development,promote industrial upgrading.Make a good function positioning in this region,give play to the leading role of government departments in logistics planning.Improve infrastructure and give play to regional advantages;Local governments should expand the scale of logistics infrastructure and adjust the layout of logistics infrastructure based on the current needs of the development of the logistics industry;attach importance to logistics talents and build high-quality logistics enterprises;build a hub-and-spoke logistics network to promote the coordinated development of urban logistics in Guangxi.
