地理与地理信息科学

电子商务与传统产业的关联关系是探究区域电商发展能力的重要视角，企业地理共聚是产业间关联的重要体现。该文利用2004—2022年河北省石家庄市跨境电商企业和制造业企业数据，采用核密度、区位熵、地理共聚指数分析县区尺度下两类企业的集聚特征及地理共聚特点。结果表明：(1)石家庄市跨境电商企业空间集聚特征明显，呈现出由单核心向多核心结构演化的空间裂变式增长，东中西部优势企业类型多且差异显著。(2)石家庄市制造业企业集聚态势明显且集聚范围不断扩大，呈现集中连片式增长；制造业企业集聚优势类型以劳动密集型为主，资金技术密集型企业主要集聚在中部，资源密集型企业集聚程度最弱且主要位于西部。(3)石家庄市两类企业地理共聚水平差异明显，中东部县区共聚水平整体高于西部且大多数县区呈现波动发展；中东部县区五金工具类、纺织服饰类、工业设备类和冶金化工类的跨境电商企业与相应制造业企业共聚程度较强，而西部县区仅以纺织服饰类和工业设备类企业共聚为主。探究跨境电商企业与制造业企业地理共聚对于分析两者关联关系及电商发展能力对区域产业外向性影响具有一定指导意义。

The association between e-commerce and traditional industries is an important perspective to explore the development capability of regional e-commerce, and the geographic co-agglomeration of enterprises is an important embodiment of inter-industry association.Based on the data of cross-border e-commerce enterprises and manufacturing enterprises in Shijiazhuang, Hebei Province from 2004 to 2022,this paper analyzes the agglomeration level and geographic co-agglomeration characteristics of the two types of enterprises at the county scale by using the kernel density method, location entropy method and geographic co-agglomeration index.It is found as follows.(1) The spatial agglomeration characteristics of cross-border e-commerce enterprises in Shijiazhuang are obvious and the number of agglomeration areas is increasing, showing the spatial fission growth from a major centre to the multi-centre structure.The central counties and districts have the most obvious advantages in the agglomeration of industrial equipment enterprises, while that in the eastern counties and districts are textile and clothing, hardware and tools, and light industry and daily-use enterprises, and in the western counties and districts are textile and clothing enterprises.(2) The agglomeration of manufacturing enterprises is equally obvious and the scope of agglomeration is expanding, showing a concentrated contiguous growth.The advantage types of agglomeration enterprises in each county and district are mainly labor-intensive enterprises, capital and technology-intensive enterprises are mainly concentrated in the central counties and districts, resource-intensive enterprises have the weakest agglomeration degree and are mostly in the western counties and districts.(3) The geographic co-agglomeration level of the two types of enterprises in each county and district of Shijiazhuang is obviously different.The geographic co-agglomeration level in the central and eastern counties and districts is higher than that in the western counties and districts as a whole.In the central and eastern counties and districts, the cross-border e-commerce enterprises of hardware and tools, textile and clothing, industrial equipment and metallurgy and chemical industries have a high level of co-agglomeration with the corresponding manufacturing enterprises, while the western counties and districts are only dominated by the co-agglomeration of cross-border e-commerce enterprises and manufacturing enterprises in textile and clothing and industrial equipment industries.Exploring the geographic co-agglomeration of cross-border e-commerce enterprises and manufacturing enterprises has certain guiding significance for analyzing the relationship between the two types of enterprises and the impact of e-commerce development on regional industrial outward orientation.
