西宁市开发区企业的供应销售物流网络结构特征

借助Ucinet社会网络分析工具,构建企业供应销售两类网络,尝试分析内陆高原城市开发区供应销售物流网络的结构特征。研究表明:①供应物流网络在国内呈"U"型结构,即东西部强,中部弱;国际上供应商较少。供应货物流动结构呈地方化、非全球化的特征,表现出显著的地方资源导向。②销售物流网络格局跟供应物流网络大致相似,国内总体也呈"U"型结构;国际上呈现全球化销售较弱。销售货物流动结构呈地方化、弱全球化的特征,表现出企业主要服务青海省内需求的基本特征,同时也表现出东部化、全球化的趋势。③医药卫生、轻工食品及服装纺织行业,产业链完整,可提升地区产业结构;冶金矿产、石油化工及机械电子电工行业,在产业链中处于中游阶段,对产业升级影响较弱;交通运输行业,在产业链中处于下游阶段,一定程度上能促进产业结构的优化升级以及经济发展方式的转变。

The Characteristics of Supply and Sales Logistics Network Structure of Enterprises in Xining Development Zone

With the help of Ucinet social network analysis tools,we built two types of networks for enterprise supply and sales,and tried to analyze the structural characteristics of supply and sales logistics networks in inland plateau urban development zones.The research shows that:1)The supply logistics network has a"U"structure in the country,that is,the east and west are strong,the central part is weak;there are fewer suppliers in the world.The supply cargo flow structure is characterized by localization and non-globalization,showing significant local resource orientation.2)The sales logistics network pattern is similar to the supply logistics network.The domestic overall is also a"U"-type structure;international sales are global.Weak.The flow structure of sales goods is characterized by localization and weak globalization.It shows the basic characteristics of the main services of enterprises in Qinghai Province,and also shows the trend of easternization and globalization.3)Medicine and health,light industry food and clothing textile industry.The industrial chain is complete,which can enhance the regional industrial structure;the metallurgical,mineral,petrochemical,and mechanical,electrical,and electrical industries are in the midstream stage of the industrial chain,and have a weak impact on industrial upgrading;the transportation industry is in the downstream stage of the industrial chain.To a certain extent,it can promote the optimization and upgrading of industrial structure and the transformation of economic development mode.
