noun
semi-monopoly; quasi-monopoly
Refers to a market situation where a single entity does not have a full monopoly but holds a dominant position, often used in economics and business contexts.

半独占状態では、価格競争が限定的になることがある。

寡占 (oligopoly) refers to a market dominated by a few firms, whereas 半独占 suggests a single firm with overwhelming but not total dominance.
Compound of 半 (half, semi-) and 独占 (monopoly). The exact historical derivation is uncertain, but the term follows a common pattern for describing partial or quasi- market structures.
