Recent works leverage export data to assess country production structure and ultimately country relative competitiveness. These works mostly rely only on the exported part of the total country output for reasons of data availability, homogeneity, and quality. Here we use the World Input-Output Database (WIOD), which offers cross-country harmonized data that accounts both for domestic production and export, to investigate to what extent export is a proxy for domestic production. We find that export mirrors remarkably well domestic production for manufacturing sectors or sectors related to physical goods. Conversely, this relation fades away for service related sectors. We found those relations consistently across most of the 40 countries for which data are available.

最近的工作利用出口数据来评估国家的生产结构，并最终评估国家的相对竞争力。由于数据的可用性，同质性和质量，这些作品大多仅依赖于国家总产出的出口部分。在这里，我们使用世界投入产出数据库（WIOD）来提供说明国内生产和出口的跨国协调数据，以调查出口在多大程度上可以替代国内生产。我们发现，出口反映了制造业或与实物相关的部门的国内生产情况。相反，对于与服务相关的部门，这种关系逐渐消失。我们在可获得数据的40个国家中的大多数国家始终保持着这种关系。
