B2B模式下中国批发企业供应等级的空间分异及影响因素

基于阿里巴巴网站提供的批发企业信息,运用Zipf位序-规模法则、泰尔指数及主成分回归等方法,对B2B模式下批发企业供应等级的空间分布、位序规模及差异特征进行分析,并对其影响因素进行探讨。结果表明:①B2B批发企业的经营模式以生产厂家为主,且钻级、皇冠级等高级别企业较少;东部沿海地区批发企业较为集中,企业数量呈现出由东向西、自南向北逐级递减的特征。②综合及不同经营模式的批发企业供应等级呈现出东、中、西的梯度分布特征,且不同经营模式下供应等级表现出不同的空间分布特征。③省区之间及省区内部,批发企业供应等级的集中分布特征明显,首位地区的垄断性较强,且不同供应等级的地区之间出现明显的分层现象。④不同经营模式下批发企业供应等级的区域差异有所不同,且差异主要来自于四大板块内部城市之间的差异,板块间差异不显著。⑤城市B2B批发企业供应等级的高低与城市的基础规模实力、信息通讯水平、文化教育水平、物流设施水平及批发业的发展基础密切相关。

Spatial Differentiation of Supply Level of Wholesale Enterprises under B2B Mode and Its Influencing Factors in China

Based on the information of wholesale enterprises provided by Alibaba website,this paper analyzes the spatial distribution,rank-size and difference characteristics of wholesale enterprises’supply level under B2 B mode by using the methods of Zipf rank-size rule and Theil index,and applies principle component regression to detect the influencing factors of supply levels.The main conclusions are as follows:1)B2 B wholesale enterprises’operation modes are mainly manufacturer-based,and there are fewer high-level enterprises such as diamond-grade and crown-grade.The wholesale enterprises in the eastern coastal areas are relatively concentrated,and the number of enterprises is gradually decreasing from the eastern China to the western and from the southern to the northern.2)The supply levels of wholesale enterprises under different operation modes show the gradient distribution characteristics from the eastern China to the western.And the supply levels under different operation modes show different spatial distribution characteristics.3)Both at the provincial and city level,wholesale enterprises’supply levels show the characteristics of concentrated distribution.The monopoly of area ranking in the first is strong,and there is obvious stratification among different supply levels.4)The regional differences of wholesale enterprises’supply levels under different operation modes are different,which mainly come from the intercity differences of the four major plates,and the differences between the plates are not significant.5)The supply level of B2 B wholesale enterprises is closely related to the basic scale of the city,the level of information and communication,the level of culture and education,the level of logistics facilities and the development basis of the wholesale industry.
