Restrictions on travel and quarantine on arrival are typical strategies imposed by public health authorities during pandemics. While much research has analyzed the consequences of policies about global public health emergencies including COVID-19, to date there has been little discussion of the social consequences of these policies. We undertook an exploratory study using qualitative research to understand the social impacts experienced by travelers as a result of the restriction policies implemented in China following its implementation of a zero-COVID policy. Using online sources and 40 interviews with quarantine hotel staff, government officials, and arrivees to China, we found that the people with a strong justification for travelling during the pandemic were significantly affected by the restrictions, resulting in them experiencing a wide range of negative social impacts, including on their: psychosocial health and wellbeing; family cohesion; social networks; the experience of unexpected and unpleasant circumstances; and a sense of persecution. These outcomes were partly a consequence of the characteristics of Chinese society and the returnees themselves, and were influenced by the government's COVID management strategies. With medical experts having dominated the battle against the virus, ordinary people's feelings and concerns were ignored. We argue that these also need to be understood and considered in the planning of public health strategies. To improve outcomes in future situations, much can be learned from the field of Social Impact Assessment (SIA), especially in terms of understanding how people are affected, and to achieve acceptance and a social licence for pandemic management strategies, the importance of meaningful community engagement, ongoing monitoring, adaptive management, and an effective grievance redress mechanism. Our paper enriches the understanding of SIA when applied in the policy arena, and it demonstrates the value of a SIA perspective for improving social outcomes in public health emergencies. It also adds to understanding the consequences of pandemics and restriction policies on people. • The concerns of arrivees have been ignored in management of the COVID pandemic. • Restriction policies have significantly affected people other than just travelers. • Although various elites dominate the battle against virus, people's feelings matter. • National policies should consider the unintended consequences of actions. • A Social Impact Assessment perspective helps analyze the social impacts of policies.

• Innovate the "structural response sensitivity weight" interdisciplinary model. • Breakthrough in research on super statically indeterminate microscopic lattice. • Assessing 100 years of sustainability data for China's construction industry. • Provides a paradigm for United Nations and regional assessments. Sustainability research in the construction industry is of great strategic significance to the ecological environment of countries worldwide. This paper innovates theoretical models such as "structural response sensitivity weight" through interdisciplinary research on advanced mathematics, engineering science, computer science, environmental management and economic sociology. The model solves the limitations of multi-factor, multi-discrete, multi-constraint and low coupling iteration accuracy. The article shows the robustness of the model through case studies. The research data shows that the construction industry in China will reach its highest life cycle assessment emission peak of 2.73 GT in 2030 and will have harmful emissions of -2.78 GT between 2061 and 2098. The social impact assessment will peak at 4.26 GT in 2048 and harmful emissions of −3.75 GT per year from 2061 to 2098. This research provides a comprehensive research theory system and reference standards for scientific calculation and accurate assessment of the sustainable development of the construction industry in various countries around the world.
