Based on a survey of 2343 rural residents in China, this paper adopts a binary logistic regression model as the analytical tool to study the impact of rural residents’ social network and sense of responsibility regarding their participation in environmental governance. The results show that the cost, frequency and scope of social network activities have positive and significant influences on resident participation in rural environmental governance. The cost of a social network is conducive to building a rural social network, enhancing the connection of interests and promoting the formation of a rural community. Extending social network objectives from family members to villagers can improve the cultural identity and emotional identity of rural residents. The increase in the frequency of social network activities can not only enhance trust among residents, but also reduce the cost of environmental governance mobilization. The scope of a social network acts as an inhibitor whereby social interaction beyond the scope of rural areas will reduce identification with rural emotions. The four dimensions, including responsibility cognition, responsibility will, responsibility emotion and responsibility behavior have significant influences on resident participation in rural environmental governance. Residents’ sense of responsibility plays the role of an introverted driving force for them to take part in rural environmental governance, which itself helps to overcome “non-participation” behaviors of “rational smallholders” to a certain extent. Furthermore, it endows rural environmental governance with resilience. So, it is of significance to enhance rural residents’ social networks and to improve rural residents’ cognition of collective responsibility.

After the outbreak of the COVID-19 pandemic, the importance of the Effectiveness of Community Epidemic Prevention and Control (ECEPC) which is directly related to the safety of people’s health and the stability of the society, is highlighted under abnormal circumstances. However, researches on Community Emergency Preparedness (CEP) and ECEPC in low and middle-income countries are of different quality. This study adopted the random sampling method. 2,250 residents from 150 communities in 140 municipalities in 20 provinces in Chinese mainland participated in the cross-sectional survey on ECEPC, with 2,112 questionnaires validly returned. Data were analyzed through descriptive statistics with optimal scaling regression model to explore the influencing mechanism of CEP and Resident Emergency Response Capacity (RERC) on ECEPC. The results revealed that 74.47% of respondents thought ECEPC was relatively good, and over 40% of respondents thought emergency risk awareness, emergency mutual-aid capacity, and psychological resilience were fairly good. Both CEP and RERC had positive and significant effects on ECEPC. The impact ranking showed the importance of emergency response system drills was ranked first at 0.165. Emergency response system could be revised and improved in practical drills. The results of the study provided new recommendations for different measures to be taken in the preparation, adjustment, and improvement phases of Emergency Response System Drills, which were conducive to building a resilient community-based epidemic prevention and control system.

The active participation of rural residents is crucial to the effectiveness of rural human settlement environmental governance. However, existing studies have rarely explored the connections between rural residents’ livelihood capital, policy perception, and their participation behavior. This study aims to reveal the relationship between rural residents’ livelihood capital and their participation in human settlement environmental governance, and clarify the mediating role of policy perception in this relationship. This study adopted the random sampling method. Using questionnaires as the data collection tool, we conducted a cross-sectional survey on rural residents’ participation in rural human settlement environmental governance among 2,460 rural residents from 25 provinces in Chinese mainland, with 2,362 questionnaires validly returned. Data were analyzed through a binary logistic regression model to explore the direct impact of livelihood capital on participation behavior, while the mediating effect of policy perception was evaluated through a mediation effect test. The results show that livelihood capital has a significant positive impact on rural residents’ participation in human settlement environmental governance, and policy perception partially mediates the relationship between livelihood capital and participation. The study indicates that improving rural residents’ livelihood capital and policy perception can effectively promote their participation in human settlement environmental governance. Accordingly, participation efficiency can be enhanced by optimizing livelihood capital and strengthening the perception of environmental policies. In the future, the research area can be further expanded to verify the universality of the conclusions, and panel data can be used to explore the dynamic evolutionary relationship among the three factors.
