英文摘要：
This paper is a contribution to interweaving two lines of research that have progressed in separate ways: network analyses of international trade and the literature on African trade and development. Gathering empirical data on African countries has important limitations and so does the space occupied by African countries in the analyses of trade networks. Here, these limitations are dealt with by the definition of two independent bipartite networks: a destination share network and\\ a\\ commodity share network. These networks - together with their corresponding minimal spanning trees - allow to uncover some ordering emerging from African exports in the broader context of international trade. The emerging patterns help to understand important characteristics of African exports and its binding relations to other economic, geographic and organizational concerns as the recent literature on African trade, development and growth has shown.

中文摘要：
本文有助于将两条以不同方式取得进展的研究路线交织在一起：国际贸易网络分析和非洲贸易与发展文献。收集关于非洲国家的经验数据具有重要的局限性，非洲国家在分析贸易网络方面所占的空间也有很大的局限性。这里，通过定义两个独立的二部网络来处理这些限制：目的地共享网络和商品共享网络。这些网络及其相应的最小生成树，使我们能够在更广泛的国际贸易背景下揭示非洲出口中出现的一些排序。正如最近有关非洲贸易、发展和增长的文献所表明的那样，这些新出现的模式有助于了解非洲出口的重要特征及其与其他经济、地理和组织问题的约束关系。
