Public concern over major agricultural product safety incidents, such as swine flu and avian flu, can intensify financial losses in the livestock and poultry industries. Crawler technology were applied to reviewed the Weibo social media discussions on the African Swine Fever (ASF) incident in China that was reported on 3 August 2018, and used content analysis and network analysis to specifically examine the online public opinion network dissemination characteristics of verified individual users, institutional users and ordinary users. It was found that: (1) attention paid to topics related to "epidemic," "treatment," "effect" and "prevent" decrease in turn, with the interest in "prevent" increasing significantly when human infections were possible; (2) verified individual users were most concerned about epidemic prevention and control and play a supervisory role, the greatest concern of institutional users and ordinary users were issues related to agricultural industry and agricultural products price fluctuations respectively; (3) among institutional users, media was the main opinion leader, and among non-institutional users, elites from all walks of life, especially the food safety personnel acted as opinion leaders. Based on these findings, some policy suggestions are given: determine the nature of the risk to human health of the safety incident, stabilizing prices of relevant agricultural products, and giving play to the role of information dissemination of relevant institutions.
公众对重大农产品安全事件（如猪流感和禽流感）的关注会加剧畜禽产业的经济损失。运用爬虫技术回顾了2018年8月3日报道的中国非洲猪瘟（ASF）事件的微博社交媒体讨论情况，并采用内容分析和网络分析具体考察了认证个人用户、机构用户及普通用户的网络舆情传播特征。研究发现：（1）对“疫情”“治疗”“影响”“预防”相关话题的关注度依次递减，在可能出现人感染情况时对“预防”话题的兴趣显著增加；（2）认证个人用户最关注疫情防控并发挥监督作用，机构用户和普通用户最关注的分别是农业产业相关问题和农产品价格波动问题；（3）在机构用户中媒体是主要意见领袖，在非机构用户中各界精英尤其是食品安全人员充当意见领袖。基于这些研究结果，给出了一些政策建议：确定安全事件对人类健康的风险性质；稳定相关农产品价格；发挥相关机构的信息传播作用。
