Outline of Research at the Start

本研究は、藤本隆宏教授の「設計情報転写論」および、柊紫乃・上總康行の「現場改善会
計論(Gemba Kaizen Costing, 以下GKC)」を理論的基盤としながら、従前より日本の製造業における強みとされてきた改善実践やトヨタ生産システム(Toyota Production System, 以下TPS)について、会計的視点から理論化することを目的とする。
また、理論化と同時に、様々な業種業態に適合可能な実務導入の方法論を創出する。現場改善会計論のこれまでの基礎理論研究に基づいた、「学際的・実践的・応用研究」である。

Outline of Final Research Achievements

We continued action research based on the basic theory of Gemba Kaizen Costing (GKC) to verify its practical application. The number of cooperating companies has expanded as follows.
(1) Housing material processing company (reported by the Japanese Association of Management Accounting). (2) Automobile and medical parts manufacturing company (reported by the Japan Cost Accounting Association, to be published in the 5th volume, 1st issue of Management Accounting Review in fiscal 2025). (3) Plating company (to be published in the above journal).
Overseas, we presented our findings at the 18th New Zealand Management Accounting Conference (NZMAC 2024). Based on a working paper that is an English translation of each chapter of Kazusa and Hiiragi (2023), “Gemba Kaizen Costing: Visualizing Kaizen Effects,” we are currently compiling a paper that compares accounting theories in three global regions with overseas researchers, which will be submitted to an overseas journal.

Academic Significance and Societal Importance of the Research Achievements

上總(2010)によれば,管理会計の研究領域は会計実務・経営実践からの「問題摘出」から始まり,調査研究,理論研究,応用研究,会計処方研究を経て,実務適用で完了する。本研究では,現場改善効果の金額測定の困難さという問題について,原価計算構造と改善効果との因果関係を究明した基礎理論に依拠しつつ,実務におけるアクション・リサーチを継続して実証した点に社会的意義がある。
また,本研究における実践研究から,現場改善からその会計的成果測定,さらに余剰生産能力のマネジメントにつながるプロセスについての新たな仮説を得た点に学術的意義がある。
