Outline of Final Research Achievements

We have explored how data-driven explorations could break a new ground in the study of international relations. Having attempted a few other projects, we have focused on the analysis of corporate ownership and control through equity investment as a new approach to power politics in international political economy. We have developed a series of theoretical models of how a shareholder may convert ownership shares into the power of corporate control as well as algorithms and methods to implement the models on large-scale databases. The analysis reveals that the rise of index, passive investing strategies and digital-transformation have expanded the size of the global capital market, that the added complexity of the market allows for some shareholders to hide their corporate influence, and that hidden influence allows for “silent” cross-border takeovers of the critical economic infrastructure and production resources.

Academic Significance and Societal Importance of the Research Achievements

本研究が開発した株式保有を通した企業支配の構造を検出する技術は、学術的には軍事力に代わる国際政治経済の新しい力の行使の実態を解明し、FDIに代わる対外投資の指標を提供し、ESG投資における責任の所在を記述するなど新しい地平を描く。企業の隠れ株主など経済安全保障のリスク検知、ESG投資の具体的なガイドライン、企業のサプライチェーン身体検査など企業や政府機関から協力要請を受け、社会実装が進んでいる
