As a common social network, the SNEM plays an important role in emergency management. Magnitude emergencies are characterized by high complexity and uncertainty, and it is impossible to rely on the government for emergency management alone. We should absorb multiple subjects to build the SNEM and carry out extensive emergency mobilization in the whole society. The SNEM can integrate resources, gather consensus, promote participation, and reduce risks. The analysis of the types, generation mechanism, subject behavior, and strategy selection of the SNEM aid in adopting appropriate mobilization strategy based on magnitude emergencies, achieving the adaptation of the SNEM and emergency scenarios. By constructing the evolutionary game model of the SNEM for magnitude emergencies, taking China as an empirical sample, this paper explores the behavior evolution law and stable strategy of the government, social organizations, and the public. The results showed that the symbiotic SNEM with a positive response of social organizations and the public under the path of high-intensity mobilization by the government is the best strategy combination, and it is conducive to maximizing the emergency joint force.
Social networks are social structure constituted by a set of social actors with embedded relationships, which has a significant impact on both perceptions and behaviors among individuals and groups. The influence of the social networks on citizens’ willingness to participate in social governance is manifested in two aspects: one is that social networks directly affects the citizens’ willingness to participate; the other is the social capital made up by social networks, social trust, and social norms affects the citizens’ willingness to participate. Drawing on a transprovincial survey regarding citizen participation in the social networks, this paper uses the Ordered Logistic model to explore how does social networks affect the citizens’ willingness to participate. The results show that (1) social networks have a significant impact on citizens’ willingness to participate in social governance, specifically, the stronger the social networks are, the higher level of the citizens’ willingness to participate will be; (2) social networks, together with social trust and social norms constitute social capital, and the social capital has a significant impact on the citizens’ willingness to participate in social governance, which is manifested; the higher the social capital stock is, the higher level of the citizens’ willingness to participate will be; and (3) from the lens of demographic characteristics, those who are male, high educated, CCP members, or from the eastern region of China are more willing to participate.
Emergency cooperative social networks (ECSNs) play a very important role in emergency management for magnitude emergencies in China recently. Based on the data set of cooperative fight against COVID-19 of the Beijing-Tianjin-Hebei region in China, using social network analysis (SNA) and asymmetric evolutionary game model, this study finds that the asymmetry between regions is comprehensively determined by resource endowment, administrative level, geographical distance, regional vulnerability, political pressure and other factors; vertical control is still the main operating mechanism of ECSNs; network derivation is caused by the superposition of multiple factors, of which political factors are very important, and asymmetry may become an obstacle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
