下游

• 병음: xià yóu
• 한자 분석: 下 = lower, below; 游 = 氵+ 㫃 (water + flowing — the act of flowing or a section of a waterway)

뜻

하류; (공급망) 다운스트림

Two main senses: (1) geographic — the portion of a river nearer to the sea, where the river is wider and flows more slowly; (2) economic — downstream industries process or sell finished goods derived from upstream raw materials. For example, in petroleum: refining and retail are downstream; extraction is upstream. Pairs with 上游 (upstream/upper reaches) and 中游 (midstream).

올바른 표현

피해야 할 표현

• 下游 in formal supply chain analysis without clarifying the industry context — upstream and downstream positions differ significantly by sector; always contextualise when the industry type is not self-evident from the surrounding discussion
