「How Japanese Business Managers See the U.S.–China Rivalry: Balancing Economic and Geopolitical Stakes
⽇本企業の管理職層から⾒た⽶中競争: 経済的利害と地政学のはざまで」
Abstract: As U.S.-China tensions rise, businesses in middle-power countries like Japan face difficult trade and investment decisions. This study examines how Japanese firm managers weigh geopolitical risks, through a December 2024 survey experiment conducted during Donald Trumpʼs second presidential term. Results show firms are highly sensitive to the risk of U.S. retaliation when engaging with China, while Chinaʼs security threat itself is less influential. Although most oppose trade restrictions, many accept U.S.-led measures targeting China, even at their own expense, while rejecting Chinese-led restrictions. These findings highlight how private-sector actors internalize geopolitical alignments, offering insight into business decision-making amid great-power competition.

「Geopolitical Risks and Global Supply Chains: Evidence from Shipping Data」
Abstract: More than 90% of Japanʼs trade activities relies on maritime supply chains facilitated by vessels. In recent years, maritime logistics has been increasingly vulnerable to geopolitical risks, large-scale natural disasters, and the enforcement of new environmental regulations. This study plans to analyze how these developments affect shipments and global supply chains by using the AIS data. Eventually, the project aims to provide evidence to support the realization of stable and resilient maritime transportation.
