解説
問 17
Incorrectア
“The value or satisfaction felt at first consumption gradually declines as the quantity consumed increases” is an explanation of the economic law of diminishing marginal utility, and is unrelated to the innovator’s dilemma.
Incorrectイ
“One’s own new product takes share away from one’s own existing product” is an explanation of cannibalization. It is competition between old and new products — a concept distinct from the dilemma, which concerns failure to respond to disruptive technology.
Incorrectウ
“A state in which a small number of customers account for the majority of total sales” is the state of sales concentration shown by the Pareto principle (the 80-20 rule), not a description of the innovator’s dilemma.
- エ
正解 The innovator’s dilemma is a concept proposed by Clayton Christensen. The more excellent and well-managed a large company is, the more it concentrates its management resources on “sustaining innovation” — responding to the voices of existing customers and steadily improving existing technology. As a result, its response to “disruptive innovation,” which initially performs worse, falls behind, and it loses its market to emerging firms and fails to secure share. Choice エ states exactly that “an excellent large company focuses on improving existing technology rather than pursuing innovative technology, and as a result fails to secure market share,” which precisely matches this definition, so it is the correct answer.
ここがポイント
- The innovator’s dilemma = a phenomenon in which an excellent large company prioritizes sustaining innovation (improving existing technology), falls behind in responding to disruptive innovation, and loses market share.
- Distinguishing confusable management and economics terms: use definitions to separate diminishing marginal utility (ア), cannibalization (イ), and the Pareto principle (ウ).
