The use of the Internet by older adults will contribute to the sustainable development of society. Existing studies have extensively investigated the influencing factors that affect older people’s use of the Internet, but ignored the behaviors of the people around them. Using data from China Family Panel Studies, we investigated the influence of peer effects on the Internet use of older people. It was found that, the stronger that peer effects are, the higher the level of Internet use among older adults. This conclusion still holds after a robustness test. The peer effects are more obvious in rural areas, due to closer community interaction. In addition, this study proves that peer effects promote Internet use by increasing the perceived importance of the Internet through mediation tests. The findings highlight the positive effects of social interaction on the Internet among older people, which is conducive to the improvement of policy practice.

Relieving the emotions of the public through government response is an important part of government emergency management. How governments respond in different situations can avoid stimulating negative emotions during emergencies? This paper analyzes the problem from the perspective of configuration; that is, this paper explores the combined effects of multiple factors on emotions. We construct the theoretical framework “Situation-Responder-Content” from situation, responder and response content, and use the government microblogs (n= 1517) from 23 major production accidents in China for the discussion with the use of fuzzy set qualitative comparison analysis (fsQCA). According to the results, the effective response types of different agencies in emergencies are summarized. Local authorities can respond in ways that include “Measures type” and “Measures-Emotion type”. Functional agencies can respond through “Measures type”, “Measures-Emotion type” and “Government feature-Driven” type. This study emphasizes that government response in emergencies is a systematic process. Responsive agencies need to release effective information on the basis of fully considering the situation and other factors. Configuration analysis should also be an important direction in government response research, which is helpful to the practice of government response in emergencies.
