【摘要】 跨境电商作为国际贸易新形式迅速崛起，一定程度上重塑了国际贸易格局。为探究这一现象，基于2016—2023年跨境电商平台亚马逊21个站点的中国品牌手机销售数据，以点、线、网顺序探究商品流空间结构特征。结果表明：(1)商品流数量经历快速增长、缓慢增长到小幅下降的阶段性变化。(2)从点要素看，商品流节点形成“大扩散，小集聚”空间格局，多数节点商品流联系类型增加，少数节点保持单一。(3)从线要素看，高流量路径主要集中于同一大洲节点间，少数低流量路径跨越洲际；商品流整体以欧洲为重心以“先西后东”方向扩散。(4)从网要素看，商品流网络全球化和组团化趋势并存，组团化更明显，欧洲和美国构成网络核心；网络社团由“欧洲—美洲”双社团破碎为“欧洲—美洲—英国”三社团。(5)经济规模、对外开放水平和互联网信息化水平等国家主体因素具有促进作用；国家间关系因素方面，地理距离具有抑制作用，贸易协定的签订具有促进作用，共同语言的影响相对弱化。更多还原

【Abstract】 Cross-border e-commerce has rapidly emerged as a new form of international trade, to some extent reshaping the global trade pattern. To explore this phenomenon, based on the sales data of Chinese brand mobile phones on 21 Amazon sites from 2016 to 2023, this study investigates the spatial structure characteristics of the commodity flow in the order of point, line and network. The findings are as follows:(1) The volume of the commodity flow has undergone a phased change from rapid growth to slow growth and then a slight decline.(2) From the perspective of point elements, the commodity flow nodes form a spatial pattern of “wide diffusion and small concentration”. The majority of nodes have an increasing number of types of commodity flow connections, while a few nodes remain single.(3) From the perspective of line elements, high-traffic paths are mainly concentrated among nodes within the same continent, with a few low-traffic paths spanning continents; the overall commodity flow diffuses in a “west first, then east” direction with Europe as the center.(4) From the perspective of network elements, the commodity flow network shows a coexistence of globalization and clustering trends, with clustering being more prominent. Europe and the United States constitute the core of the network; the network communities have fragmented from a “Europe-America” dual community to a “Europe-America-UK” triple community.(5) National-level factors such as economic scale, openness to the outside world, and the level of internet informatization have a promoting effect; in terms of inter-state relationship factors, geographical distance has an inhibitory effect, while the signing of trade agreements has a promoting effect, and the influence of a common language is relatively weakened.更多还原
