Outline of Research at the Start

本研究では、新たな価値を顧客に提供することで顧客層を分断する「分断的イノベーション」がもたらす産業構造変化に着目する。分断的イノベーションは、当該製品市場だけでなく、川上・川下に位置する関連業界も含めた、産業構造変化を引き起こすことがある。たとえば、デジタルカメラの普及によって、フィルムカメラが代替されただけでなく。フィルム・印画紙は不要となった。
本研究では、分断的イノベーションがもたらす産業構造変化のプロセスにおいて、競争力を獲得し、高収益を確保している企業と、既存の事業基盤すら危うくなっている企業とでは何が異なっているのかを検討する。

Outline of Annual Research Achievements

本申請研究では、デジタルカメラがスマートフォン内蔵のカメラ機能に代替されてきた事例のように、従来製品にはない新たな価値提案を行う「分断的イノベーション」が、関連業界の構造をどのように変化させるかを理解することを目的としている。
本申請研究では、先行する助成研究「分断的イノベーションによる競争優位実現プロセスに関する理論的・経験的研究」(課題番号:17K03954)での研究アプローチを引き継ぎ、事例研究による経験的知見を蓄積し、それに基づいてより一般性の高い数理モデルを構築し、理論・経験の両面から、新たな価値を創造するイノベーションによる業界構造変化のプロセスを考察する。業界構造変化のプロセスについて、本研究ではa)様々なイノベーションによって生み出された満足(知覚価値)が、消費者の支払い意欲(留保価格)をどのように形成するのか、b)イノベーションによって新たな価値を生み出すべく協力することが期待される「プレイヤー」間で、付加価値がどのように分配されるか、の二面から検討している。
令和2年度には、先行研究のレビューを行うとともに、事例研究のためのデータ収集、数理モデルの一般化程度を高めていく方策を検討した。令和3年度には、前年度に引き続き、事例研究のためのデータ収集、数理モデルの一般化程度を高めていく方策を検討した。令和4年度には、引き続き事例研究のためのデータ収集、数理モデルの一般化程度を高めていく方策を検討した。令和5年度および令和6年度には、引き続き事例研究、数理モデル分析に取り組んだ。
