A political analysis model by American political scientist D. Easton. Easton viewed politics as the "authoritative distribution of values," and was influenced by systems theory such as physiology and physics, and created a theory centered on the relationship between the input and output of systems and the environment. Almond and others later accepted this theory and used structural functional analysis to build a more sophisticated model. Easton's model is made up of the political system and the environment, input and output to the system, and feedback. He states that the political system is a device that converts input into output, with input = demands/support and output = decisions/policies.

アメリカの政治学者 D.イーストンの政治分析モデル。政治を「価値の権威的配分」と考えたイーストンは,生理学,物理学などのシステム論の影響を受け,体系と環境のインプットとアウトプットの関係を中心に理論をつくった。アーモンドらは後にそれを受容しつつ,構造機能分析を用いて,より精緻なモデルを構築している。イーストンのモデルは,政治システムと環境,システムへの入力と出力,フィードバックにより構成される。政治システムは入力を出力に変換する装置であり,入力=要求・支持,出力=決定・政策である,としている。
