京津冀农产品物流网络构建——基于引力模型和轴-辐网络分析

The Construction of Beijing-Tianjin-Hebei Agricultural Products Logistics Network:Based on gravitational model and Hub and spoke network analysis

为进一步优化京津冀农产品物流网络建设,基于2018年京津冀农产品物流相关统计数据,运用因子分析法、引力模型和轴辐网络分析法,实证分析了京津冀农产品物流网络构建方案。结论如下:1)京津冀农产品物流供需空间分布呈现不均衡特点:中东部地区消费需求强而供给能力弱,中南部地区供给能力较强而消费不足,北方地区供需能力都相对偏弱,区域农产品物流需求较大;2)按照各城市农产品物流综合发展水平聚类结果,确定了北京、石家庄、天津、唐山四个轴心城市;3)基于隶属度函数和轴幅网络分析,划分了以轴心城市为中心的四大农产品物流圈。4)构建了以轴-轴主干线及轴-点支干线为主,点对点支线通道为辅的京津冀农产品物流网络,并提出了优化产业布局,因地制宜发展产业优势,协调区域发展,避免同质化竞争的发展建议。

In order to further optimize the construction of the Beijing-Tianjin-Hebei agricultural product logistics network,this article empirically analyzes the Beijing-Tianjin-Hebei agricultural product logistics network construction plan based on the relevant statistical data of Beijing-Tianjin-Hebei agricultural product logistics in 2018,using factor analysis,gravity model and hub-and-spoke network analysis.The conclusions are as follows:1)The distribution of the supply and demand of agricultural products logistics in Beijing-Tianjin-Hebei is uneven:the central and eastern regions have strong consumer demand but weak supply capacity,the central and southern regions have strong supply capacity but insufficient consumption,and the northern regions have relatively weak supply and demand capacity.The demand for agricultural product logistics is relatively large;2)According to the clustering results of the comprehensive development level of agricultural product logistics in each city,four agricultural product logistics circles centered on the axis city are divided.;3)Based on the membership function and the axis-width network analysis,four agricultural product logistics circles centered on the axis city are divided.4)It has constructed the Beijing-Tianjin-Hebei agricultural products logistics network based on the axis-axis trunk line and the axis-point branch trunk line,supplemented by the point-to-point branch line channel.And suggestions are put forward as to optimizing the industrial distribution,developing the industrial advantages,coordinating the regional development and refraining from homogenous competition.
