While quarantine has become a widely used control strategy during the outbreak of the 2019 novel coronavirus disease (COVID-19), empirical research on whether and to what extent quarantine and attitudes towards COVID-19 affect mental health is scant. Using a cross-sectional online survey, this paper is the first from the Chinese outbreak to investigate how quarantine experiences and attitudes towards COVID-19 are related to mental health, and how these relationships change across the distribution of mental health scores. Using quantile regression analysis, we found that home self-quarantine is associated with a decrease in depression and an increase in happiness, while community-level quarantine is associated with decreased happiness, especially for those in the lower happiness quantile. We also found that favorable attitudes towards COVID-19 regarding the credibility of real-time updates and confidence in the epidemic control are associated with lower levels of depression and higher levels of happiness. These effects are stronger in the upper quantile of depression and the median quantile of happiness.

In recent years, there has been widespread concern regarding the carbon footprint (CF) of food waste due to the key impact of CF on climate change, particularly as China’s food waste is rising with its economic development. China has the largest scale of higher education in the world, and the amount of food waste in university canteens is considerable and cannot be ignored. This study attempts to assess the carbon footprint (CF) of food waste at Chinese universities for the first time based on a national survey. It is estimated that 1.55 million tons of food were wasted in Chinese university canteens in 2018, based on 9,192 samples covering 29 provinces in China. The associated CF was 2.51 Mt CO2eq. The top two food categories contributing to the total CF were meat and grains, accounting for 46.28% and 36.52%, respectively. Furthermore, the location of the university was significantly associated with the CF of plate waste. It also indicated that household income, meal satisfaction, sex, education, meal days, and food-saving campaigns were important factors influencing the CF of food waste. This study highlights areas that can help reduce the environmental impact of plate waste. It also provides targeted measures to reduce the associated CF of food waste in Chinese universities.

This paper investigates the Chinese rural household food waste issue from the unique perspective of religious beliefs based on 1380 samples in 26 provinces in mainland China. By using the count regression approach model, it is found that about 2.30% of the home meal is wasted on average for Chinese rural households. The empirical results reveal that religion has a significantly negative impact on residents’ food wastage, and religious rural households waste less food than their counterparts. Taking into account the possible omission of variables and selection bias, the above conclusion is still valid. Additionally, male household heads, small household size, young families, bad food storage conditions, and the poorer convenience of buying foods are positively related to the higher food waste rate in rural China. Thus, the study provides evidence that religiosity plays a positive role in reducing food waste in rural China. As most of the world’s population is religious to some extent, the finding may also apply to other countries or regions, and it implies that religion and sustainable food consumption are closely related.

With the full implementation of poverty alleviation resettlement (PAR), the restoration and improvement of the comprehensive living standards of relocated households have received increasing attention from policy researchers. The measurement of resilience and its determinants provides new ideas for PAR at the community level. This article proposes a method for examining community resilience in the context of PAR through a survey of 459 relocated households in western China and uses regression analysis to identify the determinants of community resilience. The results showed that the four dimensions of community resilience, in descending order, included: environmental resilience, economic resilience, management resilience, and social resilience. Income level and livelihood diversification were positively correlated with the community resilience index. Relocation time, relocation type, and resettlement mode were all essential determinants of the community resilience of relocated households. Finally, some suggestions were put forward, such as the need to build an interpersonal relationship network, guide pure farmers and non-farmers to transform into diversified livelihood households, and formulate a unified community action plan and interest protection mechanism so as to provide a reference for decision-making among managers to make decisions.

Under the “dual carbon” strategy, innovation driving has become the core force for corporate green transformation, with human resources, a key element of green innovation, increasingly gaining attention. This study utilizes data from A-share listed companies to evaluate the impact of China’s urban talent introduction policies on corporate green innovation, focusing on the three dimensions of green product, process, and management innovation. The results reveal that urban talent introduction policies significantly promote corporate green innovation in three areas: green product innovation, green process innovation (end-of-pipe pollution control), and green management innovation. The influx of high-quality talent and optimization of the labor structure represent vital pathways for achieving this impact. Different talent types play different roles in different dimensions of green innovation. Heterogeneity analysis indicates that talent introduction policies have a stronger promoting effect on the green innovation performance of large enterprises, technology-intensive industries, and enterprises in relatively weak regional economies. For enterprises with public–private partnerships, talent admission policies have a more pronounced impact on their green product innovation and process innovation (end-of-pipe pollution control). Furthermore, the impact of talent policy on corporate green innovations in products and processes varies with the intensity of local government intervention. This study emphasizes the key role of talent introduction policies in promoting green innovation, providing theoretical foundations and policy references for implementing sustainable development strategies and environmental protection objectives.
