- 研究成果概要
- I have made substantial progress on the project by completing two large-scale survey experiments in Japan and South Korea, each designed to examine how allied publics react to uncooperative U.S. security behavior and how justification framing moderates these reactions. These surveys were fielded with nationally representative samples using quota-based online panels, yielding more than 3,000 respondents across the two countries. The experimental design closely follows the preregistered protocol, including six treatment conditions capturing alliance undermining, direct abandonment, indirect abandonment, and strategic rebalancing justifications. The core outcomes, namely trust in the United States, support for the bilateral alliance, preferences for alternative security cooperation, and defense spending attitudes, were measured using the preregistered 7‑point scales. As specified in the preregistration, I am currently conducting OLS models to estimate treatment effects and structural equation modeling to assess the mediating roles of trust and alliance support.
In addition to the preregistered components, I expanded the survey instrument to incorporate a detailed battery of questions on how respondents evaluate major powers and the reputational attributes they assign to them. Drawing on the theoretical framework developed in the KAKENHI proposal, this battery measures domain‑specific reputations—economic, security, normative, and technological—of the United States, Japan, China, and the European Union. Respondents evaluated each actor on reliability, trustworthiness, compliance, and benevolence, enabling analysis of whether reputations are compartmentalized across domains or whether halo effects emerge. These items also allow me to examine how exposure to U.S. uncooperative behavior reshapes broader reputational assessments, providing a bridge between the alliance‑specific experiment and the larger theoretical agenda on great power reputation formation.
