UN Comtrade — Reporter–World TradeUN Comtrade 报告国对世界贸易

Directed reporter–World trade values from UN Comtrade for 13 major economies, 2015–2022. Export flows point reporter→World, import flows point World→reporter, and the weight is total trade value in USD (all HS chapters summed).

Note: this extract was pulled against partner = World only (no country-to-country partners), so it represents each economy's total trade with the world rather than true bilateral flows. It supports supply-chain exposure analysis at the economy–world level.

来自 UN Comtrade 的报告国对世界（World）有向贸易额，覆盖 13 个主要经济体，2015–2022 年。出口流向为 报告国→World，进口流向为 World→报告国，权重为美元计总贸易额（各 HS 章节加总）。

说明：本次抽取仅以 partner=World 拉取（无国家对国家伙伴），因此反映的是各经济体与世界的总贸易，而非真正的双边流向，可用于经济体—世界层面的供应链依赖分析。
