Announcement of "The Evolution of Business Strategy <Theory Edition>" Book Reading Session

Shosukabu.com Co., Ltd. (Headquarters: Nerima-ku, Tokyo; Representative Director and Chairman: Yutaka Yamanaka; hereinafter "the Company") will host a book reading session themed on "The Evolution of Business Strategy <Theory Edition>" (authored by Masahiro Kotosaka), co-organized with the Nerima Political Research Group and the Civil Affairs Division 8 Oversight Committee. According to an introduction by Toyo Keizai, this book traces the lineage of business strategy theory from antiquity, through the theoretical development of external and internal environmental analysis, to the new trends that emerged after the 2010s, presenting them as a continuous flow.

A major feature of this book is that it does not simply organize strategy theories since Michael Porter and Jay Barney as standard theories, but rather reconstructs them from the question, "Where is business strategy theory headed now?" The publisher's introduction presents four modern new trends: "Business Strategy as Practice and Action," "Strategy of Multilayered Boundaries," "Non-Market and Institutional Strategy," and "A New Era with Algorithms and Robotics," creating a structure that connects the classical with the cutting-edge.

Furthermore, this book is significant in that it regards strategy not merely as a search for a company's winning formula, but as a "frame of reference" for building sustainable competitive advantage in an uncertain environment. In new book introductions and related seminars, it is positioned as a valuable resource for corporate planners and business leaders to learn what assumptions they should make when formulating strategies in an era where rehashing past successes is no longer effective.

At this book reading session, discussions will focus on the historical development of business strategy theory, the intersection of external environmental analysis and internal resource theory, the meaning of the four new trends, and how companies should build competitive advantage in the AI and robotics era. It aims to be a valuable learning and dialogue platform for those interested in business strategy, business development, corporate planning, organizational transformation, technology, and competition.
