摘要This study examined public support for disaster-related measures(risk awareness,memory transmission,prevention facilities,and information networks)in the long-term recovery phase of a disaster-affected municipality.Focusing on Rikuzentakata City,which was severely impacted by the 2011 Great East Japan Earthquake and Tsunami,a stated-preference survey was conducted and analyzed using discrete choice models.Three research questions were addressed:RQ1 on the main effects of disaster-related measures,RQ2 on the interaction effects among these measures,and RQ3 on the interaction effects between disaster-related measures and economic-livelihood measures(ELMs).Stand-alone disaster-related measures and their within-domain combinations reduced public support,indicating dilution effects.By contrast,support increased when they were integrated with complementary ELMs.The policy implications are threefold.First,disaster-related measures should be implemented with caution in the medium-to long-term recovery process,as pursuing them alone may generate dilution effects.Second,integrated policy packages that combine disaster-related measures with complementary ELMs should be prioritized.Third,shrinking-city municipalities can better overcome fiscal and human resource constraints and enhance sustainability by leveraging complementarities across policy domains.Overall,the findings provide quantitative evidence that disaster-related policy must be reconceptualized as part of a broader policy portfolio.This insight has broader relevance for hazard-prone regions worldwide and offers international implications for long-term disaster governance in line with the Sendai Framework,the Sustainable Development Goals,and the Paris Agreement.
