Objective: The introduction of the “Broadband China” strategy significantly boosted internet access for older adults in China. This study examines the association between improved internet usage on the psychological well-being of older adults in China and explores the mediating role of intergenerational interactions, focusing on economic and emotional exchanges between older adults and their children. Method: A difference-in-differences analysis was employed to evaluate the effectiveness of the “Broadband China” strategy in enhancing internet access. Additionally, fixed-effect regressions were used to examine the relationship between internet use and psychological well-being for older adults (aged 60 and above, male and female, all of Chinese ethnicity). Results: Internet use is positively associated with psychological well-being. Mobile use and concurrent use of mobile and computers devices show particularly strong benefits. An inverted U-shaped relationship is observed between usage duration and well-being. Moderate use enhances well-being while excessive use diminishes the effect and may even lead to negative outcomes. Internet-based learning, social, and entertainment activities are beneficial, whereas the associations of internet-based work remain inconclusive. Economic interactions such as online shopping and digital transfers are positively associated with well-being, while increased reliance on virtual communication may reduce face-to-face interactions, weakening emotional connections. Conclusion: The “Broadband China” strategy played a significant role in promoting internet use among the country's older adults. While our results suggest many positive associations between internet use and mental well-being, increased internet usage is also associated with decreased face-to-face contact frequency and lower contact quality between older adults and their children. Policy Implication: Digital inclusion policies should not only expand access but also promote balanced internet use while encouraging meaningful offline interactions between older adults and their families.

This paper attempts to explore the role of non-cognitive abilities in explaining the apparent phenomenon of female advantage in Chinese universities. The results showed that female students significantly outperformed their male counterparts in both academic and non-academic performance. This advantage is robustly present in samples among different majors or level-tiered universities, and especially large in samples from humanities and social majors as well as non-key universities. Compared to male students, female students have higher levels of non-cognitive ability in conscientiousness, achievement motivation, extroversion, and emotional stability; but they have lower levels of self-confidence and lower return rates of conscientiousness, achievement motivation, and self-confidence about educational achievement. Non-cognitive abilities have been shown to play a mediating role in the formation of female dominance in school performance. The decomposition results suggest that higher levels of non-cognitive ability are the main cause of educational advantage for women, especially in terms of non-academic performance. The findings provide a new perspective on understanding the phenomenon of gender stratification in higher education and have practical implications for optimizing university policies.

We utilized the China Genuine Progress Indicator Survey, a unique national survey data from China, to explore the effects of individuals’ perceived pollution on their migration interests. Results show a significantly positive effect of perceived environmental pollution on an individual’s migration interests. A higher level of perceived pollution increases the possibility of migration by 6.5%. Meanwhile, adaptive behaviours such as using facemasks, air cleaners, or water cleaners could not be alternatives to migration. In particular, well-educated, young, high-income groups, as well as those engaged in professional and technical work, are more affected by perceptions about environmental pollution. They are likely to show higher levels of perceived pollution, which could possibly lead to the brain drain effect. Moreover, people’s environmental attitudes have moderating effects on the migration interests triggered by pollution. Our focus on potential population outflow can bear new implications for the formulation of forward-looking environmental policies.

The increasing amount of waste produced has been a challenge for human health and the environment, causing a call for effective waste management measures in which household waste separation is of great significance. Although an expanding body of literature has examined the impact of social capital on individual waste-separation behavior, few studies have explicitly discussed the endogeneity problem and the influence mechanisms. Accordingly, our study investigates the effect of social capital on waste-separation behavior and corresponding mechanisms using a national survey dataset of China. The study also reveals the heterogeneity of the influence of individual characteristics on waste-separation behavior. Our results demonstrate that social capital casts a significant positive impact on waste-separation behavior, providing opportunities for individuals’ social learning and strengthening the reputation effect. The heterogeneous effects of social capital reveal that women, higher-educated individuals, and political party members present better waste-separation behavior. Besides, the impact of social capital varies between urban and rural areas and among different age groups. Our study provides empirical evidence for policy making of household waste-separation management in developing countries from the perspective of informal institutions.

This study analyzes the causal effect of education on consumers' cognition and attitudes toward genetically modified (GM) foods. The authors propose an analytical framework to clarify the role of education levels and education content in the formation of attitudes toward GM foods and utilize education reforms in China as natural experiments to test the theoretical predictions empirically. For education levels, the authors use Compulsory Education Law's implementation to construct the instrument variable. For education content, the authors utilize the revision of the biology textbook in the Eighth Curriculum Reform to implement staggered difference-in-difference estimation. The authors use two national household surveys, the China Genuine Progress indicator Survey (CGPiS) and the China Household Finance Survey (CHFS) of 2017, combined with provincial-level data of education reforms. The education level, instrumented by the Compulsory Education Law's implementation, has an insignificant effect on consumers' cognition and attitudes toward GM foods, whereas the acquisition of formal education on genetic science, introduced by the Eighth Curriculum Reform, has a statistically significant and positive influence. This is the first study to investigate the causal effects of education level and content on consumers' cognition and attitude toward GM foods using national representative data. It is also the first to evaluate the long-term effects of the biology textbook reform in China. The findings help open the black box of how education shapes people's preferences and attitudes and highlight the significance of formal biology education in formulating consumers' willingness to accept GM foods.
