Background: It is of great practical significance to study the intrinsic relationship between cultural capital, digital divide, cognitive ability, and health of older adults in the dual social context of population aging and the digital era. Methods: We analyzed data from the 2020 China Family Panel Studies (CFPS) initiated by the China Center for Social Science Surveys at Peking University. Physical health, mental health, and memory health were set as indicators of older adults, and the relationship between cultural capital, digital divide, cognitive ability, and health of older adults was examined by hierarchical regression with moderated mediated effect methods. Results: Improvement in the health of older adults is associated with an increase in the level of cultural capital; cultural capital may bridge the digital divide faced by older adults, which in turn promotes the improvement of the health of older adults; the higher the level of cognitive ability, the stronger the effect of cultural capital on the digital divide, and at the same time, the stronger the mediating effect of the digital divide; cultural capital has a more pronounced effect on the health of older male adults living in the city. Conclusions: The results of the study show that cultural capital can have a positive impact on the health of older adults, but there is urban-rural heterogeneity and gender heterogeneity, in which the digital divide plays a mediating role, and the enhancement of the cognitive ability of older adults will be conducive to the improvement of their health, so the health of older adults should be promoted by improving the level of their cultural capital and the ability of older adults to use digital technology, thus provide references for the protection of health of older adults.

Disclosing environmental information is essential for listed firms to demonstrate social conscience. To fulfill government and public media supervision, Chinese listed firms are increasing the quality and quantity of disclosed environmental information. This elicits a new topic of interest: the correlation between media/government supervision and corporate environmental information disclosure (EID). The paper addresses this issue through data analysis and factor correlation study in data from some high-pollution firms in China during 2017–2019. The study first introduces a standardized definition for the quantification of media and government supervision, as well as the degree to which the corporation discloses the environmental information. Then, the correlations between the factors are isolated and refined to three sub-topics: (1) how public media and local government supervision affect the quality of corporate EID; (2) how is the interactive effect of public media and government supervision related to corporate EID; (3) how is the distinct ownership of corporate affect the government supervision on corporate EID. The concluding result from the above factor analysis could provide guidance for authorities to adjust certain laws and regulations so that the media and government supervision better motivates the corporate EID, and furthermore, better sustainable development of ecological environment.

The environmental pollution that accompanies economic growth has always been of widespread concern. The chemical industry is a highly energy-consuming industry in China, and the pollution this industry causes to the environment cannot be ignored. The paper is based on the Porter hypothesis and uses data from different regions of China. In this paper, we investigate the mediating role of different types of environmental regulation (divided into command-controlled, market-incentive, and voluntary environmental regulation) in positively affecting sustainability performance through green technology innovation (divided into green product innovation, green process innovation, and end-of-line management innovation). The results show that different versions of the Porter hypothesis can be accepted in Chinese chemical enterprises. This finding demonstrates that environmental regulation positively impacts both green technology innovation and sustainability performance. Green technology innovation plays a mediating role between environmental regulation and sustainability performance, especially in East China. However, the mediating effect of green product innovation is not significant. Further study shows that command-controlled environmental regulation has a more significant positive effect on sustainability performance. This suggests that the market-incentive and voluntary environmental regulation tools do not fully play their functional roles. Thus, the paper demonstrates the developmental shortcomings of environmental regulation, green technology innovation, and sustainability performance. This is more conducive to chemical enterprises improving green technology innovation and achieving long-term development and ecological environment protection.

Government supervision and media investigation play an important role in regulating manufacturing produce mode and reducing carbon emissions. In terms of theoretical implications, this study uses the tripartite evolutionary game model to investigate the dynamic decision-making process of stable strategies among three participating stakeholders: manufacturing enterprises, government regulatory departments, and media survey agencies. The payoff matrix and replicator dynamic functions of three parties are specifically calculated based on the evolutionary game theory. From a lower-carbon economy perspective, the main factors (revenue, subsidy, cost, and loss) that affect the stable strategies of three stakeholders are included in the sensitivity analysis. In terms of practical implications, this paper describes the evolutionary dynamic process of the stability condition using numerical simulation tests, and it proposes the promotion mechanism of four different supervision stages of manufacturing production mode. In the beginning and early stage, strengthened government supervision and active media investigation have a positive effect on reducing the heavy-polluting manufacturer proportion in China. Under this circumstance, the lower cost, in-creased revenue, and added subsidies all motivate firms to adopt the lower-carbon production mode. With the maturity of the supervision platform, public media will gradually reduce their investigations and interventions to the manufacturing business, and finally engage in no-investigation. This paper also demonstrates that lower penalties and subsidies are not related to the optimal strategy among three stakeholders, and the extravagant survey cost will reduce the enthusiasm of public media to investigate manufacturing firms.

The outbreak of the coronavirus disease 2019 (COVID-19) represents an alert for epidemic prevention and control in public health. Offline anti-epidemic work is the main battlefield of epidemic prevention and control. However, online epidemic information prevention and control cannot be ignored. The aim of this study was to identify reliable information sources and false epidemic information, as well as early warnings of public opinion about epidemic information that may affect social stability and endanger the people’s lives and property. Based on the analysis of health and medical big data, epidemic information screening and public opinion prevention and control research were decomposed into two modules. Eight characteristics were extracted from the four levels of coarse granularity, fine granularity, emotional tendency, and publisher behavior, and another regulatory feature was added, to build a false epidemic information identification model. Five early warning indicators of public opinion were selected from the macro level and the micro level to construct the early warning model of public opinion about epidemic information. Finally, an empirical analysis on COVID-19 information was conducted using big data analysis technology.

Purpose: Older adults are struggling in the digital age due to lower digital literacy and other reasons. The purpose of this study was to explore the relationship between digital social capital, digital divide, learning ability, and health of older adults. Methods: This study used data from the China General Social Survey (CGSS) to systematically analyze effects of digital social capital on the health of older adults using the moderated mediated effect test. Results: Digital social capital has a significant positive effect on the health of older adults and significant household and regional heterogeneity. Internet usage has a mediating impact between social capital and the health of older adults. Learning ability positively moderates the effect of internet usage on the health of older adults, but negatively moderates the impact of digital social capital on internet usage. Learning ability moderates the mediating effect of internet usage between social capital and the health of older adults. The stronger the learning ability, the stronger the mediating effect of internet usage between social capital and health of older adults. Conclusion: Digital social capital can promote the health of older adults, and internet usage and learning ability can play mediating and moderating roles in the process of digital social capital affecting the health of older adults, revealing that we should cultivate the digital social capital of older adults and improve the digital ability of older adults to improve their health.
