意味（1）

(political science) The principle that plurality-rule elections (such as first past the post) structured within single-member districts tend to favour a two-party system, and that "the double-ballot majority system and proportional representation tend to favor multipartism."

Out of that work emerged Duverger’s Law, which holds that single-member districts tend to produce two-party systems. […] And in the long run, the inexorable machinery of Duverger’s Law will ensure that the Patriot Party is folded back into the Republican Party.
