突发公共卫生事件中政务微博影响力分析

Analysis on the Influence of Government Microblogs in Public Health Emergencies

每一次突发性公共卫生事件,都会对社会经济民生造成巨大影响。在应对突发性公共卫生事件时,确保信息畅通尤为重要,政务微博在此环节中发挥了重要作用。针对公共卫生事件爆发期间政务微博数据进行分析讨论,构建了政务微博影响力评价体系,提出了政务微博在应对公共卫生事件时的工作建议。基于国内最大的微博平台——新浪微博,以28个省级行政区新闻办公厅微博账号为研究对象,利用python爬取了相关数据,通过主成分分析法构建了政务微博影响力评价体系,由创造力指标、推动力指标、互动性指标和传播力指标四个一级指标,二级指标则由关注数、粉丝数、原创微博数量等12个指标构成。针对主成分分析结果通过聚类分析法对28个政务微博影响力进行评价和比较。发现我国政务微博水平整体呈金字塔结构,发展存在不均衡不全面的问题,未来在应对公共事件时,要加强政务微博之间的信息互通以及和受众之间的互动。

Every public health emergency will have a huge impact on the social economy and people′s livelihood.In response to emergencies of public health,it is particularly important to ensure the smooth flow of information,and government microblogs have played an important role in ensuring the accurate and timely disclosure of information.After analyzing and discussing government microblog data during the epidemic period,we build the influence evaluation model of government microblogs and make suggestions for government microblogs in response to public health emergencies.Based on Sina Weibo,the largest microblog platform in China,we studied 28 provincial government microblogs during the epidemic,used python to crawl relevant data,and constructed the influence evaluation model of government microblogs through principal component analysis.The influence evaluation model consists of four primary indicators:creativity indicator,motivation indicator,interactivity indicator and spreading indicator.The secondary indicators include the number of followers,the number of fans,the number of original microblogs and many others.28 government microblogs are evaluated and compared through cluster analysis according to the results of principal component analysis.We find that most government microblogs have low influence and the current development of government microblog is uneven and incomplete.It is necessary to strengthen the information exchange between government microblogs and the interaction with users.
